Hysteresis
The level of the product in a tank is not constant but slightly varies, due for example to
filling disturbances. If the level oscillates around the changeover level (
Minimum level
),
the algorithm will constantly switch between calculating the value and holding the
previous result. To avoid this effect a positional hysteresis is defined around the
changeover point.
