Align the sensor in liquids as vertical as possible to the product sur-

face to achieve an optimum measurement.

The mounting location of the radar sensor should be a place where no

other equipment or fixtures cross the path of the microwave signals.

Vessel installations, such as e.g. ladders, limit switches, heating spi-

rals, struts, etc., can cause false echoes and impair the useful echo.

Make sure when planning your measuring site that the radar sensor

has a "clear view" to the measured product.

In case of existing vessel installations, a false echo storage should be

carried out during setup.

If large vessel installations such as struts or supports cause false

echoes, these can be attenuated through supplementary measures.

Small, inclined sheet metal baffles above the installations scatter the

radar signals and prevent direct interfering reflections.

If there are agitators in the vessel, a false signal memory should be

carried out with the agitators in motion. This ensures that the interfer-
