If using an assembly with automatic cleaning, check the correct connection of the cleaning agent
(e.g. water or air).

Calibration
The sensor is calibrated at the factory. A new calibration is only needed in special situations.

Automatic cleaning
Compressed air is most suitable for cyclic cleaning. The cleaning unit is either ready supplied or can
be retrofitted, and is attached to the sensor head. It operates at a capacity of 20-60 l/min. Optimum
results are achieved with 2 bar (29 psi) and 60 l/min.
The following settings are recommended for the cleaning unit:
