Further product information
The sensor is made of special plastic and is therefore resistant to practically all aggressive media found in water and waste water. The sensor can be mounted on any type of sewer using the appropriate adaptable stainless steel mounting shoes. When also used to measure the filling level, floor mounting is required.
