3. Application
3.1. Conditions required for the transmitter
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 measuring instrument 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.
Cross-flows should be absolutely avoided, as they could cause some damages to the
electronic part.
In order to protect the transmitter against damages, select the place of
installation so that:
• the process pressure is always kept within the admissible operating pressure
• the product temperature is always kept within the admissible temperature
• the transmitter is mechanically levelled out (e.g. to avoid vibration)
• the meter tube can be emptied in case of the danger of frost
• the measuring instrument is not arranged straight above a gully or sink hole
• the connection housing is not permanently exposed to dripping water
3.1.1. Measuring of air and gas
The electromagnetic measuring instrument can supply perfect measuring results in case of
gas-free liquids only. Air locks or deaeration in a liquid will lead to faulty measurements.
Thus, make sure that air locks or other possible parts of gas are eliminated before the
measuring device e.g. by air eliminators or that deaeration can be excluded by a sufficient
working pressure.
The measuring device is not damaged e.g. by air locks.
3.1.2. Solids
Normally, solids do not have any negative influence on the volume measurement.
The pipe diameter should always be chosen sufficiently large in order to prevent the meter tube
from being clogged in case of products with solid particles.
Due to the fact that the flow velocity of solid matters is usually lower than that of the liquid part
of the product, a higher flow fluctuation can be caused while the flow rate is measured.
The measurement of abrasive materials can cause a drifting of the measuring accuracies and,
in the end, a deterioration of the transmitter.
Caution

3.1.3. Mounting 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 a good readability and handling of the
operating unit is guaranteed.
The pipelines within the inlet and outlet pipe sections must not show any unevenness, e.g.
welding beads internally.
In the case of 3-A applications, the transmitter should not be mounted below the center line
of the flow tube.

Other Installation Considerations
5xDN 3xDN
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 and
should be avoided!
Do not place the flow meter on the suction side of the
pump! → Danger of negative pressure!
Keep the recommended inlet and outlet sections!
Avoid curvatures of space before the flow meter!
