Micropilot M FMR250 FOUNDATION Fieldbus Installation
Hauser 17
Measurement in a plastic tank
If the outer wall of the tank is made of a non-conductive material (e.g. GRP), microwaves can also
be reflected off interfering installations outside the signal beam (e.g. metallic pipes (1), ladders (2),
grates (3), …). Therefore, there should be no such interfering installations in the signal beam.
Please contact Hauser for further information.

Beam angle
The beam angle is defined as the angle
α
where the energy density of the radar waves reaches half
the value of the maximum energy density (3dB-width). Microwaves are also emitted outside the
signal beam and can be reflected off interfering installations. Beam diameter
