4.2 Sensor installation

4.2 Sensor installation
The measuring principle is generally independent of the flow profile unless static eddy
currents penetrate the measured value forming zone (e.g. after pipe elbows, in the case of
tangential occlusion or half open slides in front of the sensor). Measures to normalize the
flow profile are necessary in such cases. Suitable measures in this respect are:
● increasing the inlet and outlet lines
● using flow rectifiers
● reducing the line cross section

CAUTION
It is recommended to use protective rings (orifice protectors) to protect the inlet and
outlet edges of the sensor against mechanical damage especially when used with
abrasive media.
Protective rings are available as accessories.
