4.5 Measurement setup - Flow
In general, the following must be observed while mounting the device:
•
Mounting the sensor on the upstream or inlet side
•
Installation in the centre of the flume and vertical to the liquid
surface
•
Distance to the overfall orifice or Venturi flume
•
Min. distance to the max. height of damming for optimum accu-
racy: 250 mm (9.843 in)

Detailed project planning data can be found at the channel manufac-
turers and in the technical literature.
