In the design and construction of this equipment and

instructions contained in this manual, consideration has been given to safety requirements in respect of statutory industrial regulations.

Users are reminded that these regulations similarly apply to installation, operation and maintenance, safety being mainly dependent upon the skill of the operator and strict supervisory control.


1 INTRODUCTION

The entire description is based on the ATEX version. For different versions ( CSA / FM ) several components may be replaced in order to full fill the applicable safety regulations. However the principal as described will be still the same, in case of doubt please refer to Elster-Instromet.

The Elster-Instromet Turbine Gas Meter is a state of the art precision instrument, which measures the flow of gases by means of a turbine wheel. As a result of years of development and experience, Elster-Instromet has been able to provide a meter of unparalleled accuracy and reliability, which will give years of faithful service even under very demanding conditions.

The purpose of this manual is to provide a general guide to the installation, operation and care of an Elster-Instromet turbine gas meter. Every effort has been made to ensure that the information contained in this manual is as accurate as possible, however, the continuous improvements which Elster-Instromet makes to its products may result in small inconsistencies. Custom manufactured equipment or “specials” may also result in differences.

It is therefore prudent to consult the specific technical data and other documentation which accompanies the meter. If in any doubt, Elster-Instromet should be contacted.


2 GENERAL DESCRIPTION

The meter body can be considered a part of the pressure containing system.

2.2 Operating principle

In principle the SM-RI-2 can be build as an Mono directional (Fig 1.) and as a Bi-directional (Fig 2.) turbine gas meter.

The metering mechanism consists of a turbine rotor, a flow straightener and optional pulse sensors, which will register impulses of the blades of the turbine rotor, or pulses of a reference rotor. This hardware provides the required frequency by which means the passed volume of gas under the actual conditions can be calculated.

The flowing gas enters the meter through a built-in flow conditioner ( 1 ) that conditions the flow profile and increases the gas velocity. The gas continues along the flow channel (2) and enters the turbine rotor (3). The turbine rotor blading is designed with overlap to give complete guidance to the flowing gas and extract the maximum energy at low gas velocities. The turbine rotor’s angular velocity is proportional to the average gas velocity flowing through the meter. The gas exits the turbine rotor through, either a special designed cone (4 Fig. 1 Mono type) or by the second flow conditioner (4, Fig. 2 Bi-Di Type). Optional, every single pulse generated by the turbine rotor, is detected by means of specific ATEX certified proximity sensor(s) (5).


The big advantage from a SM-RI-2 compared to a conventional SM-RI-X is its pressure drop performance. Compared to the SM-RI-X the SM-RI-2 has about 50% of the pressure drop of a conventional SM-RI-X.

3 INSTALLATION

Fig. 6 SM-RI-2 Bi-Directional Turbine Gas meter

3.1 Installation conditions - general

The gas stream should be clean and free of liquids, dust or foreign material, which could damage the meter rotor and mechanism.

Where the gas stream is not clean, it is recommended that a gas filter of 5 micron mesh or better be installed upstream of the meter. All upstream piping should be cleaned before installation.


The Elster-Instromet turbine meter has been designed to average the gas velocity and provides accurate measurement even when the velocity profile is distorted. Where strong swirl or extreme profile distortion exists the meter may over or under register; the degree of error being dependent on the degree of distortion. The meter is essentially less sensitive to flow disturbances and upstream piping configurations than orifice plates but installations suitable for use with orifice plates can be used and will give an even better performance with the Elster-Instromet meter. Alternatively, arrangements recommended for turbine meters may be used allowing for more compact installations. Tube bundle flow straightener as described in ISO and AGA standards are also suitable.

Fig. 7 Installation recommendation

The meter being installed is an SM-RI-2 with the new X4X built-in straightener, only 5 D of straight pipe is required upstream of the meter (fig. 4) in order to keep the effect of perturbations within 0.33% for flow rates between 20% and 100% of maximum flow rates.

5 D

5 D


This permits the design of very compact installations without any effect on accuracy. It also reduces the uncertainty caused by installation effects to an extremely low level when used in conventional installations. The increase in the pressure drop with such a meter is quite small.

Where regulators or similar devices are used immediately upstream in very compact installations where jets could impinge on the meter, the use of a tee is recommended. Downstream piping may be of any configuration providing

the meter is connected initially to pipe work equivalent to the nominal bore of the meter prior to any reduction. Reducers (one size reduction), elbows, tees and full bore valves can be attached directly to the meter.

If temperature is to be measured downstream, it is recommended that such measurement be installed within 1x the diameter (1D) of the meter.

Fig 8. SM-RI-2 turbine meters should be installed horizontally.


If liquids are in the stream or if the gas is moist, the meter pipe should be sloped to allow any liquid to flow away from the meter.

Elster-Instromet SM-RI-2 Turbine gas meters may be subjected to flows of 20% higher than the maximum specified for short periods of time (not longer than 1 hour / 24 hours ) without damage to the meter.

However, excessive rotor speeds will decrease the life of the meter if such overspeeds are frequent or long of duration > 1hour/24hours.

When installing a meter outdoors, it should be protected from the direct effects of the weather. Electronic accessories must also be protected from the elements and from extreme ambient conditions. See for specific IP classification applicable data sheet of used components.


3.2 On Receipt

1. Carefully examine the shipping container for any external damage prior to unpacking. Any evidence of damage must be reported to the carrier.

2. After unpacking the meter, examine it for compliance with the ordered specifications and check that any required accessory such as a volume corrector is included. Check the test certificate supplied with the meter and ensure that the information concerning the calibration, pressure range, temperature etc. is in accordance with the actual installation.

3. A bottle of the recommended lubrication oil is also normally included.

6. Check to ensure the turbine rotor turns smoothly (use an air jet or simply blow into the inlet). The rotor should not stop abruptly or show signs of unbalance.

4. TAKE PARTICULAR CARE TO RETAIN ALL DOCUMENTS SHIPPED WITH THE METER AS THEY ARE METER-SPECIFIC AND REQUIRED FOR METER RECORDS.

5. Remove inlet and outlet covers.


3.3 Installation of the meter

After the above inspections, the meter can be installed as follows:

1. Make sure that the installation is clean, free from swarf, sand, other particulate matter or liquids. Ensure flange faces of both the meter and the installation are similarly clean and free of any foreign particles, both inside and outside the openings.

2. Note flow direction, lift the meter into the mounting position using the lifting lugs or eyebolts. Take care that the index head or other mounted devices are clear of any lifting strop.

3. Position the gaskets carefully, ensuring that there is no protrusion into the line, which would thus cause a disturbance to the flow.

For exact gasket type information please contact your gasket supplier.


4. Tighten the bolts with equal force. For recommended torque values, see table 1.

table 1 Indication of installation Torque

5. Connect pulse probes and electronics according to the diagrams accompanying the equipment. The reference pressure must be taken at the point on the meter labelled “Pr” or “Pm”. If the meter is installed in a zone classified as a hazardous area, then ensure all connections are to intrinsic safe circuits or have another means of protection (flame proof).

6. Fill oil reservoir with oil supplied with the meter and pump as required to lubricate the bearings. For further informations/intructions see chapter 4.2

3.4 Start-Up

1. The Elster-Instromet turbine meter is a high precision instrument designed to give maximum performance at its operating conditions.

The shock of a sudden pressurising of the line can damage the turbine.

The design of the installation should be such that pressurising the meter can be achieved through a small diameter tube, preferably connected so that the meter is located in the smallest volume of the part of the installation being pressurised.

2. By choosing the internal diameter of the pipe which by-passes the main valve as indicated in the table below, the flow rate will be limited to the listed value (for natural gas). The flow rate through the meter should at no time exceed the stated maximum flow rate by more than 20%.

3. If a meter is mounted in a part of the installation that had been separately de-pressurised, particular care has to be taken when subsequently pressurising the pipe work downstream of the metering installation. Preferably the downstream piping should also be pressurised through a pipe according to the table. This valve must also be operated carefully in order to prevent overspeeding the meter.

4. Check for leakage particularly around the flanges and at the Pr connection.

5. Ensure instrument devices are operating as required.

The meter must be put into service by opening the valve slowly to pressurise the line at a rate of not less than 15 seconds duration, that will allow a gradual acceleration of the turbine wheel.

4 MAINTENANCE

Before carring out any inspection the line should be de-pressurised

4.1 Periodic inspections

Like all precision instruments an Elster-Instromet turbine meter is vulnerable to abuse and operating conditions outside its specifications and limits.

It is prudent therefore to periodically check the security and running conditions of the meter. It is essential that this is be done if a significant over pressure has occurred, if the installation has been subjected to abnormal vibration or if the gas should become excessively contaminated.

Elster-Instromet Turbine meters can be inspected without removal from the line. The meter in question therefore should be equipped with the High Frequency probe option, sensing the turbine rotor blades.

When there is doubt about the right functioning of the SM-RI-2 turbine gas meter and the HF probe is connected to the TurbinScope® facility, it is possible for Elster-Instromet specialists to check the condition of the meter by remote control unless its geographical location in the world*. You can apply for this optional service at your Elster-Instromet sales department.

* depending if connection of a cell phone is possible near the meter (< 60 meter).

TurbinScope® is an additional service facility of Elster-Instromet which gives the possibility to check on the condition of the meter and its surrounding installation, without the necessity of removing the meter from the line.

``

In some cases, removal of the probe breaks the meteorological seal.


4.2 Lubrication procedure

To extend the lifetime and maintain the accuracy of a turbine meter lubrication of the bearings is necessary. Flushing the bearings with oil not only ensure effective lubrication but also removes foreign particles, which may have entered from the gas. The frequency of lubrication depends on the operating conditions and is for clean gas and normal operations. When the turbine meter is used continuously (gas flow over 20 % of Qmax ) a frequency of 3 times per year is sufficient to guarantee the lubrication of the bearings. See table 3 for quantities per size.

During periods of no flow, the interval of lubricating may be altered in accordance to the periods of use.

In the SM-RI-2 turbine meters up to DN300 the standard manual oil pumps are fitted. DN400, DN500 and DN600 are standard fitted with the Automatic Lubrication System (ALS).

- The Automatic Lubrication System (ALS) can be fitted on all Elster-Instromet SM-RI types on request.

- The pumps may be replaced by a lubrication nipple (minimess) through which the meters can be lubricated by an external portable lubrication pump (available on request).

- Automatic lubrication systems are default controlled by the Elster-Instromet flowcomputers, if no flow computer is available the ALS can alternatively be controlled by an Elster-Instromet Control Unit which contains all necessary components for control. The control unit is based on LF frequency input, 24 V DC power supply and delivers lubrication output on the requested times and volumes as per type determined. For more information about the ALS lubrication system request your sales representative or contact the website. www.elster.com

The mentioned lubricant volumes in table 3 is the total volume per lubrication interval to use for both front and rear bearing together.


5 TROUBLE SHOOTING

During operation, mechanical damage may be indicated by irregular rotation (Check first to ensure that there is a gas flow!). Damage to the bearings or turbine rotor usually results in excessive noise and/or vibration.

No inspection of the internals of the meter can be done while the line is pressurised. Read the safety instructions first.

If any measurements have to be made to the electronics, always use intrinsic safe measurement equipment, use a gas-sniffer to proof the absence of gas, vent the area where the flameproof box is located (opening doors) and finally follow the safety regulations of the country the equipment is installed in.

If the meter is located in a zone classified as hazardous, all connections must be intrinsically safe.

When there is doubt about the right functioning of the SM-RI-2 turbine gas meter and the HF probe is connected to the TurbinScope® facility, it is possible for Elster-Instromet specialists to check the condition of the meter by

remote control independent of its geographical location in the world*. You can apply for this optional service at your Elster-Instromet sales department.

depending if connection of a cell phone is possible near the meter

(< 60 meter).

TurbinScope® is an additional service facility of Elster-Instromet which gives the possibility to check on the condition of the meter and its surrounding installation, without the necessity of removing the meter from the line.


6 DISMANTLING

Before a meter may be dismantled or removed from the installation, the line must be de-pressurised.

It is important that the line is de-pressurised slowly and with care to prevent damage to the turbine and bearings. It is recommended that the gas be released through a small diameter tube selected in accordance with the pressurisation table on page 23

It is strongly recommended that dismantling of the meter and any repair to the internals, be performed by an authorised Elster-Instromet technician. Disturbance to the alignment of the internals may introduce an error to the measurement requiring a re-calibration. If in doubt, advice may be obtained from Elster-Instromet.

If any measurements have to be made to the electronics, always use intrinsic safe measurement equipment, use a gas-sniffer to proof the absence of gas, vent the area where the equipment is located (opening doors) and finally follow the safety regulations of the country the equipment is installed in.
