LiquidLevelSensing

[juergen44]

Capability 'LiquidLevelSensing'

Description
A sensor with this capability detects the hydrostatic pressure and converts it into an analogue output signal of current between 4 and 20 mA. The output signal changes in proportion with the level of the tank.
A PLC calculates the percentage of the maximum fill state value.
