Hauser
Comply with the following conditions. Otherwise you run the risk of damaging the measuring
point or obtaining incorrect measured values.
‣
The diameter of the pipe must be at least 50 mm (2").
‣
Install the sensor in places with consistent flow conditions.
‣
The best installation location is in the ascending pipe (item 1).
‣
Installation in the horizontal pipe (item 5) is also possible. In this case, you must turn the
sensor so that the measuring slit is aligned with the direction of flow at an angle of at least
12° but not more than 45°. → diagram

‣
Do not install the sensor in places where air pockets or bubbles occur (→ 6, 13, item
3) or where sedimentation may occur (item 2).
‣
Avoid installation in the down pipe (item 4).
‣
Align the sensor in such a way that the medium flows through the measuring gap (self-
cleaning effect).
5.2
Mounting the sensor
NOTICE
Mounting errors
Possibility of sensor damage, twisted cables or similar
‣
Make sure that the sensor body is protected against damage from external forces - such as
trolleys on adjacent paths.
‣
Make sure to avoid exerting excessive tensile force on the cable (e.g. from jerky pulling
movements).
‣
Make sure to observe the national grounding regulations when using metal assemblies.
The sensor can be installed directly in tanks and pipes with a suitable process connection, or
in a suitable assembly.
