2.2.2.2. IntroductionIntroductionIntroductionIntroduction

Separation vessels contain products such as Gas, Foam, Oil, Emulsion, Water, and Sand which naturally gravitate into

different phases as shown in Figure 1. Each phase has a different density.

The Tracerco ProfilerTM is an advanced Specialist Measurement instrument used to identify different phases within

multiphase systems. Employing award winning and patented techniques it measures the gamma absorption of the

process material. This enables a meaningful and accurate measurement of the vertical density distribution within vessels

to be made.

The instrument uses a vertical array of sources and

detectors (Geiger Müller Tubes), to measure and map the

different process phases with respect to vessel height.

Reliable assessment of both the interface quality and the

level of the interfaces present within the vessel are

achievable.

Measurements can be separated into a maximum of up

to ten different density bands or phases. The elevation of

the various phases can be calculated and outputs given

with respect to the instrument height.

The information provided can then be used to give

outputs to control oil and water interface levels, control

and monitor the effects of chemical additives or establish

effective sand washing regimes.

2.1. Principle of Operation for a T240 Profiler

The T240 Profiler can support either 1 or 2 separate detector arrays depending upon the application. On occasion 2

detectors are required so that the power level in each is low enough to meet the requirements of intrinsic safety over

longer measurement ranges.

Each detector may contain up to 75 Geiger Müller tubes giving a maximum of 150 for this instrument although again, the

number of actual tubes specified and their configuration depends upon the application.

With sources loaded and the arming rod in the open position the process material present between the source and

detector will attenuate the radiation. The amount of attenuation measured by the Geiger Muller is then used to calculate

the density of the intervening material.

The T229 controller collects information from each individual GM tube, and through a series of calculations determines

the density of the material. This enables a density or interface profile of the vessel to be constructed. Density bands are

allocated for each of the phases (typically Gas, Foam, Oil, Emulsion, Water and Sand). Up to 6 interfaces may be

configured. The top level of these phases can then be calculated with respect to instrument height.

2.2. A Typical Instrument General Arrangement

A diagram of a single detector system is shown below. The Profiler is typically located on a flange at the top of a vessel

and consists of 3 main components that make up the outer instrument housing. These are the dip-pipes, neck and dome.

Figure Figure Figure Figure 3333 –––– Typical RepresentationTypical RepresentationTypical RepresentationTypical Representation

The dip-pipes project into the separator through the vessel flange and consist of a source assembly and detector probe(s).

The source assembly holds the source rod in the collimator. This source rod contains a series of sources distributed

along its length. The rod is attached to an arming mechanism allowing the user to isolate the sources within the device.

The collimator has a series of small holes, which align with each source position when the rod is in the open position.

This allows narrow beams of radiation to be directed towards the detectors in the adjacent detector tube(s). When the

arming mechanism is locked in the shut position the alignment of the sources and the collimator is such that the sources

are isolated and the radiation from the gauge is at a safe level.

The dip-pipes are effectively a sleeve and datum for the instrument components and provide the pressure seal with the

vessel flange.

2.3. Detector Configuration

Each detector probe is populated with Geiger Müller tubes positioned along its length and encased within a protective

sleeve. Each probe assembly is housed within the detector dip pipe(s).

A pulse-shaping amplifier, mounted on the detector probe circuit board, is

used to produce a useable pulse signal for each Geiger tube output. The

output of these amplifiers is connected to the signal processing board via a

multi-way cable.

The number and spacing of sources and detectors is configurable and

governs the range and resolution of the instrument.

The tubes are distributed over the range of the instrument to provide the

required range and resolution of the application. On multi-detector systems

the tubes may be offset such that a better resolution is achieved.

3.3.3.3. InstallationInstallationInstallationInstallation

There are two main aspects of the profiler installation:

1. Mechanical

2. Electrical and Communications

The mechanical components are generally shipped as the following components:

1. Assembled Profiler unit consisting of probes, dip pipes, neck, dome, collimator

2. Support bracket

3. Communications breakout boxes.

4. Source, in arming rods and A type container

3.1. Installation of Support Bracket (Optional)

The support bracket is not used in all profiler applications. Where required the project will be issued with job specific

mechanical drawings that include a general arrangement drawing and a lower support arrangement drawing (if required).

Affix bottom support to suitable internal clips or local internal support at the height shown on general arrangement

drawing. Ensuring the arrows on the base are positioned in the direction of liquid flow.

Insert the dip-pipe(s) in to the vessel following review of installation information below. Pass the dip-pipe(s) through the

annulus of the bottom support, tightening the bolts fix the dip pipe in place.

Torque the dip-pipe flange to correct settings. Please refer to project specific pressure vessel calculations for suggested

gasket type and bolt torque settings.

3.2. Mechanical Installation (By Site)

All dip-pipe assemblies will be dispatched packed into a wooden crate(s). Each wooden crate containing a dip-pipe

assembly will be suitable for handling by fork-lift truck and slings and can be stored in a normal store. It is essential the

dip pipes are kept dry. If the crate is opened during storage for inspection then Tracerco recommend the crate is re-

sealed to prevent moisture ingress.

To install carefully remove the lid of the crate, where lifting equipment is required and fix lifting shackles through the lifting

lugs fitted to the titanium flange. It is recommended that the lifting shackle is a 2te rated large 'D' shackle (BS 3032 1958).

For internally mounted dip-pipes, ensure that the flange face of vessel nozzle is clean and place the joint gasket on the

nozzle flange. Using a suitable hoist lift the dip-pipe assembly out of its crate and into position above the vessel nozzle.

Carefully lower the dip-pipe assembly through the nozzle and into the vessel. When the dip-pipe is approximately 200mm

from the vessel nozzle carefully remove the fixing bolts that hold the profiler neck and dome to the titanium flange. With

the neck and dome supported continue to lower the dip-pipe assembly until it mates with the vessel nozzle, ensuring that

the dip-pipe passes through the bottom support bracket as above, if fitted.

The integrity of the titanium dip-pipe assembly must be protected by a suitable sized relief valve fitted to the vessel.

3.3. Bolt Torqueing Procedure:

Please refer to project specific pressure vessel calculations for suggested gasket type and bolt torque settings.

1. All nuts to be capable of being run down their respective bolts by hand.

2. Ensure threads are suitably lubricated.

3. Assemble the joint and secure all nuts by hand.


4.4.4.4. Radiological SafetyRadiological SafetyRadiological SafetyRadiological Safety

It is our normal practice to supply all equipment as specified except the radioactive sources. These will normally be

shipped to site prior to commissioning by Tracerco Services engineers. The sources will be shipped in a suitable type

“A” container. This ensures that the sources are safely packed and shielded for transport. When shipped to site, the

sources should be kept in a safe area (e.g. Radiographer’s store) until the arrival of Tracerco Services commissioning

engineers, who will install the source array into its dip-pipe. Prior to arrival of the sources, the site registration should be

amended to include the additional sources. Tracerco’s Radiation Protection Advisor (RPA) may be contacted for advice

with regard to licenses, registration, etc.

4.1. Source Isolation, Vessel Entry and Controlled Areas

The sources are contained within a single arming rod which can be locked with the sources in place. The lock must not

be removed by unauthorised persons.

For vessel entry during shutdown the arming rod must be locked shut to isolate the sources. This is achieved by pushing

down on the lever at the neck of the profiler (as shown in Figure 5) and inserting a padlock into the hole provided.

For UK applications a controlled area is mandatory around the Profiler, vessel or any area where a dose of dose > 7.5

micro-Sieverts/hr is measured. For non UK applications limits may differ depending on local regulations.

4.2. Cesium Profiler Variant

These sources emit a high energy (662keV) gamma ray. When entering the vessel a controlled area is required even when

isolated. The application specific radiological operating procedures must be used when dealing with this type of profiler.

The T229 does not perform multiple retries at the same time if there is more than 1

instrument connected to the same port. If it gets no response then it will try and

communicate with the other detector(s) in the system before retrying.

This ensures that a faulty channel does not cause missed updates on the other instrument.

Therefore the amount of time that it takes for a detector to register a communications

error is related the timeout period and the number of instruments on that port.

3 Failing Zeros

The number of successive updates where the value has returned zero. With an update

interval of 3 seconds, a value of 3 in this field would mean that it would take 9 seconds to

register a tube as failing.

6 Failed Zeros

The number of successive updates where the value has returned zero. With an update

interval of 3 seconds, a value of 6 in this field would mean that it would take 18 seconds

to register a tube as Failed.

1.5 High Count Factor Any update where a tube reports more than this factor times its empty count will cause

the tube to marked as faulty.

and the communications parameters. Assuming the devices are connected to the T229, the M1 and / or M2 LEDs on the


front panel should be flashing green, indicating the T229 is communicating correctly with the attached devices. A red M1

or M2 LED indicates a communications or configuration problem which must be resolved before proceeding. It is unlikely

the Status LED will be green. This will be addressed later using the Alarm Status tool to reset any alarms.

6.3.3. Configuring Alarms and Fault Reporting

The diagnostics built into the T229 and associated devices provide detailed status, warning and fault reporting registers.

These are combined into one overall warning register and one overall alarm register. Depending on the system design

and desired functionality, any of the bits in the alarm register can be programmed to generate a critical alarm in the critical

alarm register.

Most of the bits in the warning and alarm registers will automatically clear if the condition setting them is cleared, so an

additional set of warning and alarm registers are provided with bits that are required to be reset by the user.

Four bits in the alarm register are used to report stage failures. A stage can be deemed critical so that its failure is

reported in the alarm register. A stage can also be associated with up to 3 groups, where the failure is not reported until

a pre-set number of failures have occurred in the group.

than one group, or not assigned to any group as required. If a stage is important then it can be marked as CriticalCriticalCriticalCritical.

In a system with two interleaved probes or devices, it may be desirable from a redundancy point of view to allow a whole

device to fail without generating an alarm. This can be achieved using the Maximum GapMaximum GapMaximum GapMaximum Gap setting. Setting the Maximum Maximum Maximum Maximum

GapGapGapGap to 1 will result in the failure of a stage not being counted if the adjacent stages are still working. This has the effect

of only counting tube pair failures.

Once the source registersource registersource registersource register (refer to section 11.1) has been configured it is necessary to define the upper and lower limits

and Float Value for 20mAFloat Value for 20mAFloat Value for 20mAFloat Value for 20mA parameters. Each value must be within the range of the source register and use the same

value within that register is between 0.0 and 10,000.0 kg/m3 then we can assign the Float Value for 4mAFloat Value for 4mAFloat Value for 4mAFloat Value for 4mA to be 0.0 and

the Float Value for 20mAFloat Value for 20mAFloat Value for 20mAFloat Value for 20mA to be 10,000.0, this is a typical configuration.

The T229 includes a facility to provide corrected density values, if a user is particularly interested in the true density value

for a particular stage. In some profiler configurations, there is a difference in how much radiation is absorbed between

oil and water. This difference is exagerated in the calculated the oil and water densities, so calibrating using water will

result in the reported oil density being slightly lower than the true value.

6.3.7. Dynamic Density Band Correction

Dynamic density band correction provides the user with the ability to calculate a single phase transition density setpoint

on the fly based on an average product density. This feature is aimed primarily for use in applications where the average

density of oil and water are likely to become very close. The configuration below uses the oil/emulsion interface as an

example.

Figure Figure Figure Figure 69696969 –––– Dynamic Density Band CorrectionDynamic Density Band CorrectionDynamic Density Band CorrectionDynamic Density Band Correction


6.3.7.1. Choosing a Density Band to Correct

The first step in configuring this feature is to select a Phase Transition DensityPhase Transition DensityPhase Transition DensityPhase Transition Density SetpointSetpointSetpointSetpoint to become dynamic, if we were

to make the oil / emulsion phase transition setpoint dynamic in a typical Profiler application the possible interfaces would

look like this:

1: Gas

Phase 1 to Phase 2 Transition Density Setpoint 0

2: Foam


3: Oil


4: Emulsion


5: Water


6: Sand

As can be seen from the table, it is the Phase 3 to Phase 4 Transition Density SetpointPhase 3 to Phase 4 Transition Density SetpointPhase 3 to Phase 4 Transition Density SetpointPhase 3 to Phase 4 Transition Density Setpoint that needs to be corrected to

affect the oil / emulsion interface. To correct the transition setpoint dynamically we must configure the T229 to calculate

an average oil density

6.3.7.2. Calculating an Average Reference Density

To determine the average density within a phase we must carefully select a fixed range of stages that will consistently be

within the desired phase, in this example, oil.

When considering this function, the heavier oil will naturally settle closer to the emulsion therefore it is stages at the

bottom end of the oil phase that we must use to determine the average density.

To achieve this, the first parameter we must configure is the firstfirstfirstfirst rrrreference eference eference eference sssstagetagetagetage, this defines the uppermost stage

guaranteed to be in the chosen reference band. The number of stages and exact location of the first reference stagefirst reference stagefirst reference stagefirst reference stage

will be project specific.

The second parameter is the number of reference stagesnumber of reference stagesnumber of reference stagesnumber of reference stages used to determine the average phase density and guarantee

that all referenced tubes are always within the same phase. Again this value will depend on the number of stages and

exact location of the first reference stage for a specific project.

The calculated average density will be restricted between the Low Clipping Limit of Average Reference DensityLow Clipping Limit of Average Reference DensityLow Clipping Limit of Average Reference DensityLow Clipping Limit of Average Reference Density and

the HighHighHighHigh ClClClClipping Limit of Average Reference Densityipping Limit of Average Reference Densityipping Limit of Average Reference Densityipping Limit of Average Reference Density. . . . Should the calculated average density exceed these limits it

will be clipped and a warning bit will be set in the Density Band Correction Status Density Band Correction Status Density Band Correction Status Density Band Correction Status WWWWordordordord defined in section 6.3.7.6. The

value selected for the Low Clipping Limit of Average Reference DensityLow Clipping Limit of Average Reference DensityLow Clipping Limit of Average Reference DensityLow Clipping Limit of Average Reference Density must not be less than the set-point configured

procedures are intended to be followed by production operators during start-up and shutdown of the Profiler.

Prior to start-up check that the plant control system is not using the Profiler for control and the system is switched off.

Move the arming rod as shown in to the open position and switch the system on. Check that the indications coming back

from the system are representative of the vessel conditions. If the vessel is shown as full of sand then the arming rod is

not aligned, re-check that the arming rod is in the fully open position. When the system has stabilised and is

representative of the vessel conditions, switch the plant control system over to Profiler control.

The practical route to conforming to the above is described in the system hook-up diagram. If connections need to be

made, then this drawing must be followed. The drawing also shows the screening method necessary for the system to

conform to the EEC directive on Electromagnetic Compatibility.

The Tracerco appointed manufacturer should only make repairs to the printed circuit board(s) of the Tracerco Profiler.

Any deviation from the production standard could invalidate its hazardous area certification. Even applying a soldering

iron to a joint can leave the board in a condition that invalidates the certificate.

Changing the signal processor PCB’s is possible provided it is a straight forward swap and the wiring diagrams are

followed. Any other PCB exchanges are not possible. For anything more than signal processor PCB exchange please

contact Tracerco services.

8.2.1. Safety/Handling Precautions

Precautions on vessel entry will involve the isolation of the sources. This is explained in the appended local rule under

sections Source Isolation, Labelling, Designated Areas, Failure of Source Isolation, Labelling, Designated Areas, Failure of Source Isolation, Labelling, Designated Areas, Failure of Source Isolation, Labelling, Designated Areas, Failure of Shutter to isolate the Arming Rod prior to Vessel Shutter to isolate the Arming Rod prior to Vessel Shutter to isolate the Arming Rod prior to Vessel Shutter to isolate the Arming Rod prior to Vessel

entry and Physical Damage (internal)entry and Physical Damage (internal)entry and Physical Damage (internal)entry and Physical Damage (internal)

Take care in the area of the dip pipes when working in the vessel as any damage may make removal of the source rod or

probes difficult.

For removal of the Arming Rod assembly refer to the section in the appended local rule under the heading Source Source Source Source

Security.Security.Security.Security. The assembly is heavy and may require a crane to ensure safe handling.

When removing the probes from the dip pipes take great care not to bend them. If they are inadequately supported they

bend easily under their own weight to the point where damage may occur. For this reason, we recommend securing the

probes to a suitable support (e.g. length of angle iron) which will facilitate safe handling.


8.3. Replacing a T240 Processor Board

Note that this procedure only applies to removal of the signal processor board itself and does not cover all of the aspects of site safety, EHS, electrical isolation procedures and local rules which are applicable to safely gain access to the Profiler dome and associated wiring.

1111 Make the operations team aware that a detector is to be turned off – this will have a minor effect on the interface levels.

2222 Identify the serial number and instrument tag for the Profiler in question

3333 Determine if the detector to be repaired is A or B

4444 Go to the appropriate control panel in the safe area and identify the galvanic isolator providing power to the detector in question. There are instrument tags on the terminal group markers and adjacent to the galvanic isolators to speed up the process.

5555 Identify the I.S. terminals associated with the galvanic isolator and disconnect the knife connections.

6666 Verify at the field side of the terminals that there is no outgoing power supply.

7777 Check the label on the Profiler dome, making sure it has the correct serial / tag number and if correct, remove the dome to gain access to the signal processor boxes.

8888 Identify the signal processor box for the detector in question. Each box has a label on the front. Once you have identified the correct box then remove the lid.

9999 Perform a secondary check and verify that there is no power at the signal processor box on terminals 1 and 3 of the orange connector

10101010 Disconnect the orange connector from the signal processing box.

11111111 Disconnect the fibre patch cable paying special attention to colour coding of the cable in association with Rx and Tx on the signal processing board. Make a note of which colour patch cable connects to Rx to make sure we get it right when reconnecting.

12121212 Remove four board retaining screws.

13131313 Remove board from box and install new signal processing board, ensuring jumpers on the new board match the board being removed.

14141414 Reconnect the orange power connector.

15151515 Reconnect the fibre optic patch cable making sure we get the right connections.

16161616 Replace the lid on the signal processing box

17171717 Replace the dome.

18181818 Return to the control panel and connect the I.S. terminal knives to apply power the repaired detector.

19191919 Measure the DC voltage at the outgoing field terminals. If the detector is powered you will measure between 8.5VDC and 9VDC. If the detector is not powered then you will measure 16VDC in which case it will be necessary to verify that the field side wiring is correct.

8.4. Routine Maintenance/Inspection

Radioactive sources require a routine wipe test every 2-3 years depending on local legislation.

The installation requires a monthly inspection to confirm the presence of the sources, warning signs and source shutter

position indicators.

To maintain optimum performance Tracerco also advise a health check on every vessel shutdown.

10.10.10.10. Appendix A: T240 Profiler VariantAppendix A: T240 Profiler VariantAppendix A: T240 Profiler VariantAppendix A: T240 Profiler Variant

A Galvanic Isolator, normally fitted in the main panel, powers each detector probe with 10VDC. Communication between

the probe and the T229 is achieved using Modbus protocol. Communications in the field is over a fibre optic cable. The

Fibre optic signal is converted to an electrical signal in the main panel using a Fibre optic modem.

10.1. Installation

10.1.1. Electrical Supply

Each probe within the Tracerco ProfilerTM has its own independent intrinsically safe power supply. Each supply is a

Pepperl + Fuchs Isolating Power Supply unit mounted in a safe area. These units typically supply 100mA at 10VDC. One

or two probes may be fitted in each profiler depending on the application and range required.

The supply requires a two core screened cable with an outer armour, and 500VAC or 750VDC isolation between cores

and armour.

• The armour at the safe area is to be insulated (not connected to ground).

• The armour at the Profiler will be connected to the neck plate and terminated there so that any RF is not radiated

into the dome.

The inner insulation of the cable carries through the neck plate into the signal processor box via a feed-through gland. It

is necessary to bare about 15mm of the cable screen to allow the shielding to make contact

NOTE NOTE NOTE NOTE ENOUGH CABLE MUST BE PRESENT ENOUGH CABLE MUST BE PRESENT ENOUGH CABLE MUST BE PRESENT ENOUGH CABLE MUST BE PRESENT BETWEEN THE TWO GLANDS TO ALLOW THE SIGNAL PROCESSORS TO BETWEEN THE TWO GLANDS TO ALLOW THE SIGNAL PROCESSORS TO BETWEEN THE TWO GLANDS TO ALLOW THE SIGNAL PROCESSORS TO BETWEEN THE TWO GLANDS TO ALLOW THE SIGNAL PROCESSORS TO

The two-core cable carries on to the power-in connector. Before connection is made to this two-part connector, the

ferrite bead must be slipped in place (as shown on the hook up drawing) and insulated with amalgamating tape.

Strip the end of the cable for connection to the connector and sleeve the screening. Take the 0V and screen drain wire

(sleeved) to terminal 4 on the power-in connector. This terminal is not identified but is the most left terminal and is shown

clearly on the systems diagram. The +ve wire is connected to terminal 2 (second from the right)

The armoured cable must not be connected to the metalwork of the Profiler, and the armouring should not protrude

through the cable gland into the dome.

10.1.2. Communications Fibre

Data transmission between the field signal processing units (hazardous area) and fibre optic converters in the Tracerco

control panel (safe area) is achieved using multi-mode fibre optic cable supplied and installed by Tracerco or the client.

The optical cables are connected as shown in the hook-up diagram. ST-ST type fibre connectors are used on the signal

processing unit(s) and fibre optic converter(s).

Note: Tracerco recommend an 8-Core fibre optic cable, but could be any number of cores from 6-Core to 12-Core.

The final connection to the Profiler is generally made via a field mounted, fibre optic breakout box, mounted as close to

the Profiler dome as possible. This allows minimum disruption to the field cables as replaceable ST-ST patch leads are

used to make the final connection.

The optical breakout box splits the 8-core cable into four paired optical signals, two cores and two spare for each probe.

Connection within the breakout box can be achieved by splicing the cables or using a suitable adapter and connectors

(ST connectors are recommended). Only one adapter between each cable is to be used.

The user-defined slew rate configured here is resumed once the override or fault state has ended, and the output has returned to the normal state. If the slewing is reconfigured whilst slewing is active, the new slew rate will take effect immediately, and will not affect the DAC set point. Default: 0 (240mA/s).

the calibration date to provide a correction for source decay. Data written to these registers will be

copied to the RTC. Operation of the RTC is maintained in the event of a power interruption by a

backup capacitor, but only for about 4 days. To help spot RTC failures, when date data is written to

these registers, a backup copy of the date is recorded in Flash.

The backup date must be updated every time the date changes correctly, i.e. the serialised date

increments by 1, but only if there are no RTC errors reported in register 00020 or bit 4 of register

00020 is already set indicating the backup has already been used.

Count ControlCount ControlCount ControlCount Control This register controls and reports the status of the calibration count. Write zero to the register to

initiate a calibration count. Write 1 to the register to terminate the count. The status of the count is

reported as follows:

Bit Description 0 1 = count in progress 1 1 = count complete

2 1 = count time expired with errors 3 1 = count terminated on request

4 to F 0, Reserved

Bit 0 is set to show the gathering of a calibration count is in progress. This should take the time

specified in register 00062 or in register 00063, with an allowance for small differences in update

interval and the size of the update intervals of the attached devices. Bit 0 is cleared when all attached

devices have completed their count gathering, and Bit 1 is set. If a device reports errors, or there are

communications errors with a device and the calibration count cannot be completed in the time set

in 00062 or in 00063 plus 20 seconds, then Bit 1 and Bit 2 will be set. Writing 1 to terminate the count

will result in Bit 1 and Bit 3 being set.


Count Time Count Time Count Time Count Time

RemainingRemainingRemainingRemaining

This register shows the minimum time in seconds, for the calibration count gathering. If the count

time is not divisible by the update interval of the attached devices, then the actual calibration count

will be nearest longer multiple of the update interval. Note that devices can have different update

intervals, so the actual count times may differ. The actual time taken is recorded with the calibration

count total so that the average rate can be calculated. The permitted write range of this register is

100 to 5000 seconds. When a count is in progress, this register will show the count time remaining.

Writes to this register while a count is in progress will be acted upon, and the count will either continue

or terminate depending on the value written. This setting is the same as the setting in register 00063.

so the actual count times may differ. The actual time taken is recorded with the calibration count total

so that the average rate can be calculated. The permitted range of this register is 100 to 5000

seconds. Writes to register 00062 will be duplicated in this register. (This is for compatibility with

older versions of T229 where register 00063 was reserved and the count time was set by 00062.)

disabled. Set this register to 1 for a conventional IIR filter with a fixed filter factor, 2 for a conventional

IIR filter with a dynamically chosen filter factor. The range of this register will be extended if new

filtering methods are adopted in the future. Note that setting individual sensor filter factors to 0 will

also disable filtering for that particular sensor regardless of the setting in this register. Setting the

individual sensor fast and slow response times to the same value when dynamic filtering is selected

will effectively change the filtering for that sensor to fixed.

These figures are used in the density calculation, and are calculated from the stage combined

failed, affecting the empty and full count rates. These values are read only and not user adjustable.

Uncorrected density values are calculated from the stage combined count rates, stage combined

the reference densities are calculated, using:

� = �� Where: ρe = Calibration empty count rate reference density I = Stage combined count rate Ie = Stage combined corrected empty count rate K = Stage density calculation k factor

If there is at least one working sensor in a stage, then the combined count rates will not include data

for any failed or failing sensors, and the density can be calculated as above. When there is only one

failing sensor (remaining) in a stage, then the density must be frozen at its last value, until the stage

either recovers or fails completely.

When a stage has failed, the density for that stage is interpolated from the nearest above and below

non-failed stages. If the failed stage is the top or bottom stage, then the next lower or next higher

stage density is used.

When an interpolated density is calculated, the value is in proportion to the distances between the

interpolation stage point and the higher and lower stage measurement points.

This register controls the density band correction function. The usual function of this correction is to

monitor the average density of some of the stages known to be in oil, and use this to modify the phase

transition density between oil and emulsion. The current implementation supports modification of

either the higher phase transition density, in this case the oil/emulsion transition, or the lower phase

transition, in this case the foam/oil transition. The oil phase is normally phase 3, but any phase can

be selected for the correction. Phase 1 does not have a lower transition, so only the high transition

can be modified. Phase 6 does not have a higher transition. The phase and correction are selected

by a value in this register.

Bit 0 is set if 57131 contains an invalid setting, though this should be trapped when attempting to

write invalid configurations.

Bit 1 is set when density band correction is disabled.

Bit 2 is set if the stages defined for the reference band are not used in the instrument (either the

reference band stages configured in registers 57132 and 57133 exceed the total number of stages

reported in register 00128, or no sensors have yet been assigned to one or more of the reference

band stages).

Bit 3 is set if the order is not:

phase transition density n-1/n (or lower system density limit when n = 1) < low average density clip

limit < high average density clip limit < phase transition density n/n+1 (or high system density limit

when n = 5)

Bit 4 is set when correcting a higher transition density (register 57131 bits 1 to 5) if:

phase transition density n/n+1 (or high system density limit when n = 5) - high average density clip

limit ≤ set point offset

Bit 4 is set when correcting a lower transition density (register 57131 bits 9 to D) if:

low average density clip limit - phase transition density n-1/n (or lower system density limit when n =

1) ≤ set point offset

Bit 7 is set when none of the reference density stages are error-free.

Bit 9 is set if any of the individual stage densities deviate from the average density for the reference

band, by more than the permitted deviation.

Bits A or B are set if the average density is clipped by the low or high limit.

Bit D is set if any of the warning bits (9 – B) are set.

Bit E is set if any of the configuration error bits (0 to 4) are set. The correction does not take place.

Bit F is set if any of the error bits are set (0 to 4, and 7). The correction does not take place.

When correction is enabled but an error or warning is reported, bit D of register 57109 is set.
