flows at a high precision.
The measuring device is suitable for measuring conductive liquids.
The FMQ converter is microprocessor controlled. It supplies the transmitter with a switched and
regulated coil current.
The signal generated at the electrodes is amplified in the converter, conditioned and shown in
the internal measuring registers both as flow rate and volume information.
Volume pulses (pulses per volume unit) are output for controlling and regulating purposes.
The instantaneous flow rate is output as an analog signal of 4...20 mA according to the desired
range of 0...100 %.
When leaving the factory, each device is adjusted in such a way that only the power supply and

4. Mounting
4.1. Conditions required for the transmitter
In any case the transmitter has to be installed in the product line and the converter has to be
supplied with voltage.
When selecting the place for the installation of the flow meter you should in any rate ensure that
the housing can be opened for service work whenever desired and that the flow meter can be
simply removed, if necessary.
Equalising currents between the transmitter and the converter have to be absolutely avoided, as
they will cause measuring errors.
To protect the transmitter against damage, select the place of installation so that:
•the process pressure is always kept below the admissible operating pressure
•the product temperature is always kept below the admissible temperature
•the transmitter is mechanically mounted (e.g. to avoid vibration)
•the meter tube can be emptied to protect from freezing
•the converter housing is not permanently exposed to water

Air and gas
The electromagnetic flow meter can supply good measuring results in the measurement of gas-
free liquids only. Air locks or deaeration in a liquid will lead to incorrect measurements.
Thus, make sure that air locks or other possible parts of gas are safely separated before the
measuring device e.g. by air eliminators or that outgassing can be avoided by a sufficient working
pressure.
The measuring device is not damaged by air locks.
Particulates/Solids
Normally, particulates parts do not have any negative influence on the volume measurement.
The pipe diameter should always be chosen large enough to prevent the meter tube from being
clogged by the solids.
Due to the fact that the flow velocity of solids is relatively lower than that of the liquid part of the
product, a higher flow fluctuation could be caused while the flow rate is measured.
The measurement of abrasive materials can cause a drifting of the measuring accuracies over
time and, in the end permanante damage to the flow tube.

Arrangement
12
Fitting position –electrode axis
Due to the principle described, the fitting position –to a certain extent –can be selected any way
desired. The basic condition for accurate measuring results is, however, a full and gas-free meter
tube.
If possible, the electrode axis should be horizontally arranged, in order to avoid a deposition of
gas bubbles or solid particles on the surface of the electrodes. Therefore, a slightly ascending
pipeline is advisable, preferably with a deaerating possibility at its highest position.
The fitting position should be chosen in such a way that good readability and use of the display
(if equipped) is possible.
The pipelines within the inlet and outlet pipe sections must not show any unevenness, e.g.
welding beads to assure uniform flow.

Suggestions for installation
freier Auslauf
<5m
freier Auslauf
Wrong
At the highest point of the pipeline. Gas bubbles
accumulate in the transmitter. →Faulty measurement!
Wrong
Descending pipe:
At the end of the conveyance of the metered product
the pipe runs empty. →Measuring errors!
Correct
Preferred mounting position:
Rising pipeline and horizontal pipe section before an
ascending pipeline
Descending pipelines of a length of more than 5 m have
to be equipped with a deaeration valve after the flow
meter.
Correct
In case of a horizontal pipe conduct the mounting
position is placed in slowly increasing sections of the
pipe.
Correct
Provide a culvert for free inlet or outlet. The transmitter is
permanently filled with liquid as demanded.
Long lines after the flow meter always have to be
equipped with a shut-off device. If it is placed before the
flow meter, a vacuum will be caused in the metering pipe
by the big kinetic energy in the liquid column when
shutting off. This can damage the lining of the tube!
Do not place the flow meter on the suction side of the
pump! →Danger of negative pressure!

Installation requirements for 3-A sanitary applications
5xDN 3xDN
Keep the recommended inlet and outlet sections!
Avoid curvatures of space before the flow meter!
Correct
In horizontal applications a slope of greater than 5
degrees is required to ensure that proper
drainage occurs in the pipeline.
