Technique and Application

E10205 1.01

Function

The function of the flow controller is based on the thermo-dynamic principle.The sensor is heated internally a few degrees C comparedto the medium into which it projects. When the mediumflows, the heat generated in the sensor is conducted awayby the medium, i. e. the sensor cools down. The tempera-ture within the sensor is measured and compared to thetemperature of the medium. The state of flow can be derivedfor each medium by the temperature difference attained.

Function of thermodynamic flow controllers

On the basis of this functional principle EGE manufacturesflow monitors for liquid and gaseous media.

Areas of application for flow monitors

Thermodynamic flow monitors function without anymoving parts, therefore they are not subject to failure dueto corroded bearings, torn impellers or deflector deforma-tion. This reliability is highly valued in many industries.Today, flow monitors are used both in liquids and in air,and are employed even in explosive environments.

Monitoring of cooling

– The cooling water on welding machinery is monitoredusing compact stainless steel devices. This ensures suf-ficient cooling even for rapid cycles, otherwise the wel-ding robot will be switched off.

– The cooling lubricant flow is monitored continuously inprocessing centres. The tools are protected and have agreater service life.

– In metal processing, e.g. rolling mills and wire drawingmachines, the rolls and coils will be cooled continually.This is monitored by thermodynamic sensors. Due to therough environmental conditions the sensors are desi-gned for up to 160 °C and settings are made away fromthe heat with special amplifiers.

Monitoring of flow medium

–The run-dry protection of pumps is a frequent applica-tion, which often uses compact sensors with time delay.

– In dosing technology the aggregate, usually small flowquantities, is measured exactly by means of inline sen-sors. These sensors are inserted like a pipe into the line.

– Monitoring of filters and sieves can be ensured bymedium flow control; if the flow is progressively redu-ced, the filter must be renewed. Where this is not carriedout, the pump is switched off in a second stage shouldthe medium flow drop further. This uses a sensor withtwo switching points.

Run-dry protection of a feed pump

Sensors for explosive hazard environments

–The monitoring of cleaning processes using aggressivemedia at times is often only possible with special mate-rials, e.g. hastelloy or tantalum.

– Extraction systems for hazardous vapours at laboratoryworkstations as well as the hall ventilation in the hexaneprocessing industry are monitored using airflow sensors.

– CIP/SIP processes can be monitored and documentedwith flow monitors.

Sensors

The probe is made of special steel in one piece, using arobust electronic and mechanical constructions. By meansof this, absolute tightness and a high pressure resistanceis obtained. The chemical stability of the sensor materialmust be verified individually for every applicationAssembly is independent of flow direction. A basic requi-rement is that the sensor tip must be completely surroun-ded by the monitored medium, whether the medium flowsor is at rest. With smaller cross sections care must betaken that the sensor tip does not narrow the pipe profileconsiderably.In order to avoid function failures due to flow turbulence,no parts which influence flow cross-section or flow direc-tion should be installed immediately before or behind asensor. Recommended values for inlet and outlet are 4 to8 times the interior pipe diameter.

Assembly

Sensors with short thread-pieces of the STK... type areparticulary suited for fitting into T-pieces. Sensor length isdesigned in such a way that the sensor tip is completelyimmersed in the medium without touching the oppositeside.Sensors with long thread-pieces of the ST... type are sui-table for larger pipe diameters or for use with longerassembly thread-pieces.Sensor threads are G-pipe threads to DIN ISO 228 andalso comply with the BSP standard. A flat gasket centeredby a step on the sensor ensures a good seal. A good sealcan also be ensured using Teflon tape. For pressure above30 bar or very high screw-down torques, a flat gasket maybe damaged, especially if it is made of plastic. In this case,a recess must be incorporated into the fitting which willkeep the gasket in the right position in the case of highloads. PTFE gaskets must always be used with this tech-nique. For high pressure applications, metal gaskets mustbe used.

The standard materi-al for gaskets is AFM30/34. Specialgaskets made ofother materials suchas moving iron, cop-per or PTFE are alsoavailable on request.A rising pipe shouldbe used in case ofopen systems or inthe presence of airpockets. Depositsand air pockets donot impair sensorfunction in the caseof lateral assembly,providing the sensoris completely immer-sed in the medium.Assembly from be-low assures flow

monitoring function even if there are air pockets in thepipe. However, the monitored medium level must not fallbelow the upper edge of the measuring tip. Assembly fromabove is only applicable if there is no air in the pipe.

NPT threads

NPT threads can be provided as an alternative for all typeswhich have a G1/2 or a G3/4 thread. NPT threads are coni-cal and must be screwed into an equally conical counter-part. Two types of NPT threads must be distinguished:

NPT thread to ANSI B 1.20.1

This thread does not ensure a good seal by itself andrequires the use of a sealing medium, e.g. Teflon tape. It isnot possible to use flat gaskets with this type of thread.

NPT thread to ANSI B 1.20.3

This thread does ensure a good seal by itself and requiresno further sealing medium. When this type of thread isused, special attention must be paid to the kind of metalused for both parts of the thread, so as to avoid metal sei-zing when the parts are screwed tight.

Media

The sensitivity of thermodynamic flow monitors dependson the thermal characteristics of a medium. The detectionrange of a standard sensor for oil, for example, is threetimes as great than for water and for air is approx. 30 timesgreater than for water due to the reduced heat conductivi-ty. Unless stated otherwise, the technical sensor data arespecified for water.

Flange

Standardised pipe connections are required particularly inthe chemical, pharmaceutical and foodstuff industries.Sensors for use in these areas are supplied with flangeconnections per DIN or ASME. Sensor and flange form acorrosion-proof connection using laser or inert gas shiel-ded arc welding.

Food-approved screw connections

For hygienic reasons the food and pharmaceutical indu-stries place special demands on the mechanical and elec-tronic characteristics of sensors.

Flow monitors with food-approved connections, e.g. Triclamp or dairy pipe connections (DIN 11851) complywith the 3-A sanitary standard 28-03. Due to the tempera-ture changes involved, the usual cleaning cycles CIP andSIP place a particular demand on sensor electronics.Therefore, special protective measures are taken. Sensormaterials for these applications is mainly the special steelAISI 316 L. Customer-specific connections, e.g. GEA-Varivent or APV flanges are available, as are other specialmetallic materials.

Extra long sensors

Flow monitor sensors are available in screw lengths of25 mm to 300 mm. Sensors for use in explosive envi-ronments are made of two components if longer than110 mm and joined corrosion-proof through laser wel-ding. The sensor length should be selected such thatthe measuring tip is within an area of stable flow cha-racteristics.

Main applications are: – detection of small flow velocities in large section

pipes– mounting of the sensor with a standard flange– use of extra long welding sleeves if the piping is

surrounded by a supplementary insulation.For these cases, special shapes can be supplied up toa maximum length of 300 mm. Immersion depth "L" isdetermined by the distance between the sealing faceand the sensor tip. Stainless steel 1.4571 (AISI-316 Ti) isused for this special model.Standard lengths which can be supplied are: L = 80 and120 mm; in the Ex-area 80, 110 and 140 mm.

Inline

Inline sensors are inserted directly into the line of a pipe.This design does not feature any measuring pins protru-ding into the flow. EGE inline sensors SD of series 500 aresuitable for flow volumes from 0.5 ml/min to 6 l/min; EGEinline compact devices can also monitor flows up to 30l/min. These sensors excel through smooth measuringpipes, low pressure loss and fast response to flow chan-ges. A multitude of connection options are available.

Chemical stability of sensor housings

The chemical stability of the materials used must be veri-fied individually for every application. Basically, no pro-blems occur if the sensor and the piping are made of thesame material. It is always advantageous if the sensorhousing is made of a more noble material than the piping.The screwed cable gland on the rear side of the ST... sen-sors is designed in nickelplated brass. Order materialPVDF for screwed cable glands in applications that arecleaned with alkaline cleaning agents as is the case, forexample, in the food industry.

Stainless Steel belongs to the group of chromium-nickelalloys containing further components such as molybde-num or titanium. The proportions of the different alloycomponents is critical to the resistance to corrosion in themedium. For this reason, there exists a large number ofmaterials identified by numbers to the DIN 17442 stan-dard. Due to its good corrosive resistance in many areasof application, AISI-316 Ti (VA4) stainless steel is a fre-quently used material. It may be used in installations usedto obtain water, in air conditioning systems, in food pro-cessing industries such as dairy products, meat products,beverages, wine production or in kitchen installations.Stainless steels have a restricted stability in chlorinated orpoorly oxygenated atmospheres. Special alloys must beused for such applications.

Special materials

Hastelloy B2 (2.4617) belongs to the group of highly cor-rosion-resistant nickel-molybdenum alloys.This material has excellent characteristics in reducingmedia, e.g. in hydrochloric acid of any concentration andfor a large range of temperatures. It can also be used inhydrochloric, sulphuric, acetic and phosphoric acidmedia. Good resistance against corrosion such as pitting,crevice corrosion, chlorine induced stress, corrosioncracking, hair-line corrosion, abrasion and corrosion wit-hin the heat influence zone allows for a large range ofapplications. In the presence of oxidising componentssuch as iron or copper salts, the use of this material is notrecommended.Hastelloy C-22 (2.4602) belongs to the group of high corrosion-resistance nickel-chromium-molybdenum-tung-sten alloys. The material is characterised through high

resistance against crevice corrosion, pitting and stresscorrosion cracking in oxidising and reducing media. It alsodisplays good behavior in the presence of a large numberof corrosive media, including strong oxidants such as iron(III) chloride and copper (II) chloride, hot media, e.g. sul-phuric acid, nitric acid, phosphoric acid, chlorine (dry), for-mic acid and acetic acid. Furthermore, it has satisfactorycharacteristics in humid chlorine gas, as well as in sodiumhypochlorite and chlorine dioxide solutions.

Titanium (3.7035) is a light metal with mechanical strengthvalues equivalent to those of high quality steel. The goodchemical resistance of this metal is due to the fact that anoxide film is formed on its surface, as is also the case withstainless steels. If this protective layer undergoes mecha-nical damages in an oxygenated enviroment, it is immedi-ately renewed (titanium will resist even aqua regia).Titanium is not stable in environments containing no oxy-gen or in reducing enviroments. It is particularly suitablefor applications in chloride-containing media. Experiencein the chemical industry and in paper bleaching factorieshas shown that titanium is the only material allowing undi-sturbed production. The excellent characteristics of tita-nium also give optimum results in sea water coolingsytems and sea water de-salinising plants. The material is particularly suited for the application ofcoating with other metals and metal ceramics. These sup-plementary coatings noticeably increase its chemical sta-bility and thus the lifetime of sensor housings.

Flow ranges for EGE-Inline-Compact models

High temperature

High temperature sensors are manufactured from tem-perature-resistant components and feature connectionpipes with PTFE housing.The functional range of these special sensors of series400 is specified as +10...+120°C. Temporarily 135°C ispermissible for max. 10 min. High temperature sensorsof series 500 can be used for media temperatures of upto 160°C/320°F

EX sensors

Sensors for gas and dust explosive environments aredesign approved to ATEX 100a and operated with anapproved switching device of series SZA... or SEA...Subject to approval the use of flow monitors is possiblein areas for devices of category 1 and category 2.

Stainless steel 1.4571 (AISI 316 Ti) is used as a standardmaterial for all sensors. All other stainless steels such asHastelloy, Monel and bronzes can be provided on request.Corrosion resistance of the materials to be used must bespecifically checked for the intended application.

Connection

Flow monitoring sensors are available with a M12 plugconnector or fixed cable. The connection cable from thesensor to the amplifier may be up to 100 m long. Fordistances above 30 m a shielded cable is preferred. Inall cases the chosen wire strength must be checkedagainst the requirements.

Amplifiers

Terminal rail devices

The terminal rail devices SKZ... and SKM... evaluate thesignals from the sensors and provide relays or analogoutputs. Adjustment is via two potentiometers accessi-ble from the front. 6 LEDs indicate the flow state. Theswitching devices SKZ offer an additional switchingdelay and temperature monitoring. When installingamplifiers it must be ensured that the devices are notsubject to heat build-up.

EX devices

For Ex flow sensors switching devices SEA... and SZAare available. They have their own intrinsically safe cir-cuit to which the sensors are connected. This circuit iselectrically isolated from the mains circuit and therelays or analog output. Notes on installation:1. All Ex-Amplifiers must be installed outside the

hazardous area.

2. The installation of the amplifier must al least meetprotection to IP 20 EN 60529.

3. When installing the amplifier there must be a safedistance between intrinsically-safe and unsafe con-nections. The minimum distance is 50 mm.Alternatively each connection can be equipped witha shrink-sleeve or crimp connection.

LED array

All flow monitors feature an array of LEDs giving a visu-al indication of the flow tendency. If the red LED illumi-nates, the flow falls short of the preset limit and theswitching output is not enabled. The yellow LED indica-tes that the limit has been reached and the output ena-bled. In addition to the yellow LED a further 4 greenLEDs may illuminate representing a relative measure forhow much the limit has been exceeded.

Compact devices

Compact devices integrate amplifier and sensor withinone housing. This permits setting a limit value directlyat the measuring location. The cabling is thus reducedto the less interference-prone mains supply cables andthe switching output.

Designs

Compact devices are available in an all stainless steeldesign (SC 440) and a design with PBT plastic housing(SN 450 / LN 450). Types SC 440 have been proven formore than 10 years in industrial applications and excelthrough their ruggedness and small shape. The familiesSN 450 / LN 450 come in a multitude of electricaldesigns. The devices are available as direct and alter-nating current versions and fitted with switching, relaysor analog output. Special designs further incorporatelimit temperature monitoring or a shut-down time delay. Inline compact devices

Inline compact devices

Inline compact devices SDN 500... are inserted inlineinto a pipe. The measuring pipes are smooth inside anddo not have any components protruding into the flow.They are characterised by short response times and alarge detection range. Due to their small shape they canalso be used where installation room is sparse. TheSDN 500... are fitted with PNP, relays, or analog out-puts. For pulsating flows the EGE programme containsa compact device capable of detecting very short flowsof smallest amounts at the start of the flow.

Technique and ApplicationTerminology


Detection Range

This is the range of flow rate within which a switchingpoint can be set at the amplifier. The setting ranges andthe temperature drift differ for various media. If not spe-cified, the medium is water. At the borders of the detec-tion range, the temperature drift of the settingpoint willbe significantly higher.

Working range

The working range indicates the section of the detec-tion range for which the flow data is specified. At theouter limits of the detection range, this data is reduced.

Nominal flow

For each sensor, data corresponding to its own nominalflow is measured. This is nessesary because responsecharacteristic curves of sensors are non-linear.Consequently the various sensor characteristicsdepend on the location of the chosen operating pointon the curve. As a rule, the nominal flow-point is set inthe middle of the portion of the (simple logarithmicrepresentation of the characteristic) curve which appe-ars to be linear. For this operating point, the followingvalues may be defined: switching on and off times,stand by time, hysteresis and temperature response.

Supply voltage

The supply voltage is the voltage range within EGESensors function safely. For direct current supplies itmust be ensured that the limits are maintained evenincluding residual ripple.

Current consumption

The current consumption is the maximum value of the idlecurrent Io which the flow monitor draws without load.

Switching current

The switching current indicates the maximum continu-ous current for the switching output of the device. ForPNP outputs this value applies to an ambient tempera-ture of 25 °C. At higher temperatures the maximumswitching current is reduced. For devices with relaysoutput the value is related to the utility category AC-12or DC-12 in accordance with EN 60947-5-1.

Switching voltage

The switching voltage indicates the maximum voltage (inclu-ding residual ripple) to be switched with the relay output.

Switching power

The switching power indicates the maximum power tobe placed on the output relays.

Ambient temperature

The ambient temperature indicates the maximum andminimum permissible temperatures for the sensor.

Temperature medium

The temperature range for which a sensor is rated.Applies to the medium to be monitored.

Temperature gradient

The change of the medium´s temperature within a defi-ned period of time is called temperature gradient. EGEsensors have a temperature gradient up to 250 K/min.for water. If the change of medium temperatureexceeds this value, there will be a malfunction of theflow controller.

Start-up time

The start-up time is the period of time required by the flowdetector to reach a stable state after the operating volta-ge has been switched on. Prerequisite is that the mediumflows at the rated velocity and that the sensor has adap-ted to the temperature of the medium before switching thesupply voltage on. The start-up time is prolonged in a sta-tic medium and reduced if the medium flows faster thanthe rated value.

Reaction time

The reaction time combines the switch-on and -off time.Switch-on time elapses from the beginning of the flowuntil the switching point set at the amplifier is reached.Switch-off time characteristic results for the flow sensorsat pump shut-down. If the set switching point is close tomaximum flow, the time elapsing between the pump shut-down and the indication of the flow decrease is short. Ifthe switching point is close to the static value, the off-transition time will be long.

Compressive strength

Pressure resistance relates to the sensor casing. Standardmodels with metal casings will withstand pressures ashigh as 100 bar. Up to the indicated maximum pressure,the sensor provides a steady signal and the casing suffersno damage.

Protection

The protective system indicates the protection of the sen-sors against penetration of foreign bodies and wateraccording to EN60529

Delay

The variable time delay which can be set between 0 and25 seconds becomes active during flow standstill (drop-out delay). If the medium ceases to flow and the amplifierdisplay indicates this state, the relay contact is actuatedonly after the set delay. During the delay period the yellowLED lights up together with the red LED.

Cable break monitoring

Cable break monitoring shuts off the flow monitor outputif no sensor is connected or if the sensor cable has beensevered. In case of cable severing, "flow failure" signal isdisplayed.


Technique and ApplicationSetting instructions

Setting instructions

Setting with flow off

1. Install the sensor in the flow duct and switch on theappliance. Wait for ready state.

2. Carry out the potentiometer adjustment so that thered LED lights up.

3. When the medium begins to flow, at least one greenLED should light up.

Setting with flow on

1. Install the sensor in the flow duct and subject it toflow. Switch on the appliance. Wait for ready state.

2. Carry out the potentiometer adjustment so that twogreen LEDs light up.

3. If the flow is interrupted, the red LED should light up.

Setting for flow below threshold

This adjustment is only possible if the flow rate lies wit-hin the measuring range of the chosen sensor.

1. Install the sensor in the flow duct and switch on theappliance. Apply the specified flow. Wait for readystate.

2. Set the potentiometer so that the red LED just lightsup.

3. When the flow increases, the red LED is extinguis-hed, the yellow LED lights up and the sensor swit-ches.

Setting for flow higher than threshold

This adjustment is only possible if the flow rate lies wit-hin the measuring range of the chosen sensor. 1. Install the sensor in the flow duct and switch on the

appliance. Apply the specified flow. Wait for readystate.

2. Set the potentiometer so that the first green LEDlights up.

3. If the flow rate decreases the green LED will extin-guish first, then the yellow LED then the relay dropsout and the red LED will light up.

The switch point for flow velocity is set at the switchingamplifiers SKZ… and SKM… with two potentiometersfor coarse and fine adjustment. If the flow velocities arehigher than the detection limit of the connected sensor,flow failure or reduction will be displayed once themedium flow velocity has dropped back within the sen-sor detection range.

Time delay and limit temperature of medium

Desired values can be set by means of a potentiometerlocated on the switching amplifier.Values are indicated on a scale for SKZ... models. Allother models have a 20 step setting potentiometer.Turning clockwise increases time or temperaturevalues.If the set time lag has not yet elapsed, the yellow LEDwill remain alight, even though the red LED indicatesflow failure.

Analog output

The SKM 420 GA supplies a current intensity whichdepends on the flow speed. The output current range isdefined from 4 mA to 20 mA. The dependence betweenflow speed and output current is non-linear. The detec-tion range is adjusted over two potentiometers: “Range( ) and “Compensation” ( ). The lowest value (>4 mA,1. green LED) is set with the “Compensation” potentio-meter at the smallest flow speed to be monitoring andthe highest value (20 mA, 5. green LED) is set with the“Range” potentiometer at the highest flow speed to bemonitored. The graph shows the characteristic linesobtained with the different settings.

LED functions flow

Red:Flow has been interrupted or the flow ratehas fallen below the specified value. The"flow" relay has dropped out.

Yellow:The set flow rate has been reached, the"flow" relay pulls in.

Green:The set flow rate has been exceeded. Thereis extra flow capacity.

Red:The set temperature value is reached andthe "temperature" relay has pulled in.

Yellow and Red:Flow is below the set value. "Flow" relayremains pulled in until the set switch-offdelay runs out.

EX area certification

The sensors belonging to Series 400, as well as ampli-fiers SEA… and SZA…, have a EG-Type Examination.The corresponding technical limit data and the specialinstructions concerning incorporation and connectionexpressed in the certificates of conformity must becomplied with.

Use in category 1 and 2 (zone 0 and 1)

In zone 0 and 1 only sensors having an EC designapproval per ATEX 100a must be used. If the sensor isinstalled outdoors, a corresponding lightning protectionmust also be installed. This accessory is inserted in thesensor line, between the sensor and the switchingamplifier. It limits lightning induced voltages in the sen-sor line and diverts them to earth.

ATEX 100 a

Since 1st July 2003 only devices with ATEX approvalmay be used in explosive environments throughoutEurope. All EGE sensors have the relevant approval.The operator of a plant is responsible for dividing thehazardous areas into zones. The zones are zone 0, 1 or2 for gas and zone 20, 21 or 22 for dust. Depending onthe requirements of the operator EGE supplies appro-ved devices with approval certificates for the respecti-ve zones.In dust explosive areas the maximum surface tempera-ture of the sensor will always be stated and must beobserved by the operator. For gas explosive sensorsthe approved temperature categories will be stated.With the exception of mining, sensors can be suppliedfor all industries. Special dimensions or different mate-rials are also possible.

These sensors are made of titanium and arecoated with a metal-ceramic material layer.Coated sensors display chemical resistancepractically comparable to chemical charac-teristics of PTFE or Hastelloy. Unlike PTFEsensors, coated sensors display the sametemperature behaviour as stainless steelsensors, with high temperature gradients.The high surface hardness of the coatingprotects the sensor against abrasion, thusconsiderably increasing its durability. Theperfectly smooth surface virtually eliminatesdeposits.
