Carrying out calibration
The calibration process measures the height of the sensor float. The float height rises as the fill level
increases.
During calibration, the tank is filled with water in several steps. The exact position of the float is
measured at each step. The computer then knows the position of the float at every fill level.
These values are stored in the memory.
The following types of calibration are available:
▪ Automatic calibration.
▪ Manual input.
Planning calibration
Before you start calibration, you must plan the float heights at which you want to enter the fill level.

Calibration point 29
Calibration point 01
e.g.: Calibration point 21
Calibration point 00
Calibration point 02
The table below shows an example of what a planned calibration may look like. The values may be
different for every tank. You cannot plan the fill levels at given float heights. The fill levels depend on
the size and shape of the tank. In the example, the tank has a capacity of 7200 litres.
