Installation in narrow shafts
In narrow shafts with strong interference echoes, we recommend using a stand pipe resp. an
ultrasound guide pipe (e.g. PE or PVC wastewater pipe) with a minimum diameter of 100 mm.
Make sure that the pipe is not soiled by accumulated dirt. If necessary, clean the pipe at regular
intervals.
The pipe must be provided with a sufficient venting hole (A) (Ø 5…10mm) at the upper edge.
Flow measurement
•
Install the device at the inflow side, as close above the maximum water level H
max
as possible
(take into account the blocking distance BD).
•
Position the device in the middle of the channel or weir.
•
Align the sensor membrane parallel to the water surface.
•
Keep to the installation distance of the channel or weir.
Example: Triangular weir
