In liquids, direct the sensor as perpendicular as possible to the prod-
uct surface to achieve optimum measurement results.

To reduce the min. distance to the medium, you can also mount OP-
TISOUND 3020 C with a beam deflector. By doing this, it is possible
to fill the vessel nearly to maximum. Such an arrangement is suitable
primarily for open vessels such as e.g. overflow basins.

Fig. 10: Beam deflector
The ultrasonic sensor should be installed at a location where no
installations cross the ultrasonic beam.
Vessel installations such as for example, ladders, limit switches, heat-
ing spirals, struts etc. can cause false echoes that interfere with the
useful echo. Make sure when planning your measuring site that the
ultrasonic signals have a "clear view" to the measured product.
In case of existing vessel installations, a false signal suppression
should be carried out during setup.
