Mounting screws and nuts supplied. Level measurement Flow measurement Differential measurementChapter 1: Switch-on point, switch-off pointFor the switching behaviour of a relay there are two variants: Units of length may only be altered immediately after a reset of the transmitter After determing the length unit, this can only be altered when all other parametersare also changed.

Replace it by the numerical value of your unit of measurement.

The maximum fum current is 20 mA; for 24 V supplyExternaltemperature sensorAn external temperature sensor can be connected to the Prosonic transmitter.

The separate transmitter electronics is mounted in an IP 40 plastic housing or on an IP 10 mounting plate for control panel mountingNotes: If the symbol flashesthen the Prosonic FMU is indicating a warning and tries to continue measuring. All transmitters have a separatelimit switch inputRight: If a different linearizations mode is selected, the characteristic entered manually orsemiautomatic remains stored in the Prosonic FMU, without being used.

The digit at the extreme left is selected and flashes. If the actual maximum flowrate of the channel has been entered inV2H7, then the creep value entered is a function of the entry.

For crest length greater than 8. Steps 3 to 8 must be repeated until thelevel and the volume have been entered for all points. The cables of different groups must be separated.


Power supply unit 24 V DC for sensor heatingwith integrated overvoltage protection for power supply.

The linearizationtable is still in the memory, but no longer active. Adjustment can be carried out in the reverse order.

During this time in which the optimum frequency is attained the lastmeasured value is displayed. The certified sensor ensures that the measuring system can be usedin explosion hazardous areas.

The Prosonic FMU transmitter must be installed outside the explosion hazardousarea. The change of length unit ismade in matrix field V8H3. The measurandfor the volume is entered fmk V2H4. The LED of the relay lights up when the relay energises. The cables within onegroup can be in parallel.

When measuring the difference ffmu average, channel 1 shows the unchanged measurandof 80 sensor. Every field shows one parameter. Relays Prosonic FMU When measuring levels, for example,where the liquid surface is not steady, a steady reading can be obtained with the aid ofthe integration time.

Due to the ringing time characteristics of the sensor, there is a zoneimmediately below it from which returning echoes cannot be detected. Mounting theall-weather protective cover on the IP 66 protective housing is also illustrated. When the last digitis reached selects the leftmost digit again. Caution highlights actions or procedures which, if not performed correctly, may lead topersonal injury or incorrect functioning of the instrument.

The cable is shielded by metallic braiding. The fmuu are accessed via the slot and index number. When all parameters have been entered, the matrix can be locked see chapter 8. Thetypes of linearization, horizontal, cylindrical tank and tank with conical outlet, aredescribed in sections 4.


Depending upon the positionat which it is mounted, the external limit switch can be used to detect maximum orminimum limits. Signal below Signal above The average value is indicated in channel 2 of the Prosonic FMU i. The associated level is registeredautomatically. Setting the operatingmodeNow enter a number in V8H0 for the mode: Allother modes are fmh in chapter 4. IP 66 protective housingOrder No.: The following entries are needed: Flowrates in open channels and weirs Water levels Control of rakes and pumps Levels in silos and tanks Determining the volume or mass of contents on silos and tanksMounting,commissioning,operationThe transmitters Prosonic FMU, have been designed to operate safely inaccordance with current technical, safety and EU standards.

The characteristics are entered at up to32 points as pairs of values water-level rate of flow for each point. It is divided into the followingsections: If linearizationmanual ffmu later re-selected, the measuring properties of the Prosonic FMU are thesame as before.

The end of the measuring range is determined by the attenuation dmu the ultrasonic pulseby the air as well as by the strength of the reflection from the product surface. It is entered as a percentage, referred to the maximum rate of flow Qmax ofthe flow as given in the Tables in Appendix A or the largest value for flow rate of thelinearization curve.
