Operating conditions: Installation
Installation instructions
Note the following points:
• The measuring device is designed for mounting on tabletops, walls or pipes.
• The high oscillation frequency of the measuring tubes ensures that the correct operation of the measuring
system is not influenced by pipe vibrations.
• No special precautions need to be taken for fittings which create turbulence (valves, elbows,
T-pieces etc.) as long as no cavitation occurs.

Zero point adjustment
All measuring devices are calibrated using state-of-the-art technology. The zero point obtained in this way is
printed on the nameplate. Calibration takes place under reference conditions (
Therefore, a zero point adjustment is generally
not
required!
If a zero point adjustment is desired, please note the following points before performing one:
• Adjustment can only be performed under stable pressure conditions.
• The zero point adjustment takes place at zero flow. This can be achieved, for example, with shutoff valves
upstream and/or downstream of the sensor or by using existing valves and gates.

• A zero point adjustment is
not
possible if an error message is present.

Inlet and outlet runs
There are no installation requirements regarding inlet and outlet runs. If possible, mount the sensor upstream
of fittings such as valves, T-pieces, elbows etc.
