JUMO MAERA S28
Level probe
The level probe measures the level of liquids continuously and hydrostatically. In ventilated tanks, filling heights from 2.5 to 100 mH2O can be achieved. The level probe is equipped with integrated overvoltage protection as a standard feature. Examples of where the level probe is used include water management, well water, and surface water.
