Measure: LevelSensors

Description

Installation of sensors indicating the filling level of storage tanks or additive reservoirs. Thus it can be supervised if any storage tanks or reservoirs are running dry or overflow. The aim is to ensure a desired filling level in all reservoirs and storage tanks.
