Tip:
VEGAPULS
66 is optionally also available with antenna extension.
Hence the antenna length can be selected such that the antenna end
protrudes 10 mm (0.4 in) out of the socket.
Align the sensor in liquids as vertical as possible to the product surface
to achieve 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, for example, ladders, limit switches,
heating spirals, struts, etc. can cause false echoes that get super-
imposed on 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.
