Installation conditions for
level measurements
L00-FMU30xxx-17-00-00-xx-005
• Do not install the sensor in the middle of the tank (3). We recommend leaving a distance between the sensor
and the tank wall (1) measuring 1/6 of the tank diameter.
• Protect the device against direct sun or rain (2) ä 26 "Weather protection cover".
• Avoid measurements through the filling curtain (4).
• For solid application where bulk solid cones appear, align the sensor membrane perpendicular to the surface.
• Make sure that equipment (5) such as limit switches, temperature sensors, etc. are not located within the
emitting angle . In particular, symmetrical equipment (6) such as heating coils, baffles etc. can influence
measurement.
• Never install two ultrasonic measuring devices in a tank, as the two signals may affect each other.
• To estimate the detection range, use the 3 dB emitting angle .

1½" 11° 5 m (16 ft) 0.48 m (1.6 ft)
2" 11° 8 m (26 ft) 0.77 m (2.5 ft)
In narrow shafts with strong interference echoes, we
recommend using an ultrasound guide pipe (e.g. PE
or PVC wastewater pipe) with a minimum diameter
of 100 mm (3.94 in).
Make sure that the pipe is not soiled by accumulated
dirt. If necessary, clean the pipe at regular intervals.
