Product information: "BADU® Niveau BNR 400"
Automatic water level regulator with conductivity sensor to monitor the pool or its technical surroundings. The water level is determined via two contact surfaces /sensors. The sensors have a very flat design, thus the regulator can also be used with flat skimmers. The advantage of the level regulator is that it is unaffected by ambient conditions (temperatures). Furthermore, the sensor pins are also unaffected by dirt, unlike float switches. Thus, the BNR 400 offers multiple convenient safeguards against flooding.
