3.2 Sensor installation
3.2.1

Determining a location

Electromagnetic fields
Do not install the flowmeter in the vicinity of strong electromagnetic fields, for example near
motors, variable frequency drives, transformers etc.
Upstream / downstream
● No pipe run requirements, that is straight inlet/outlet sections, are necessary.
● Avoid long drop lines downstream from the sensor to prevent process media separation
causing air / vapor bubbles in the tube (min. back pressure: 0.2 bar).
● Avoid installing the flowmeter immediately upstream of a free discharge in a drop line.
