Some measuring points have only very little space between ceil-
ing and water surface. In such cases, for example in closed storm
overflow basins, horizontal mounting of the sensor is recommended.
The radar impulses must be directed via a 45° reflector - for example
a stainless steel sheet - to the water surface.

Information:
With this mounting arrangement, the reference plane mentioned in
chapter "Technical data" no longer applies. There is an offset that
must be taken into account for the adjustment. Note the distance
measured at min. level with the reflector, for example 2.5 m. Enter
this value as min. adjustment/measuring range begin. Determine the
difference between the min. and max. level, for example 1 m. The dis-
tance for the max. adjustment results from 2.5 m - 1 m = 1.5 m. Enter
this value as max. adjustment/measuring range end.
