Ultrasonic flow sensor DSM2420

differential pressurefor water

Sensor made of special plastic; resistant to aggressive media Special characteristics Mounting in the duct by means of adaptable stainless steel mounting shoes Use in EX atmosphere with FDL400 measuring device with integrated Z-barrier Description The DSM2420 sensor is a combined sensor for simultaneous measuring flow velocity and level in open or accessible closed channels of all types and shapes. 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.
