Installation of the sensor using a flange plate
• For installation of the unit you need a bore hole in the tank lid. The
bore hole must have a minimum diameter (d) to enable sufficient
transfer of the measured signal to the probe. The diameter depends
on the wall thickness of the tank lid:
Wall thickness [mm]
Bore hole diameter [mm]
• The flange plate is mounted with the flat surface showing to the
tank and fixed with screws. Place the sensor seal (A) and the
adapter seal (B).
• After mounting, the sensor housing can be aligned. It can be rotat-
ed with respect to the thread (process connection) without restric-
tion. Even if rotated several times by 360° there is no risk of dam-
age to the sensor.
