The Siemens SITRANS FMS500 is an electromagnetic flow sensor for the volume measurement of conductive liquids in water, wastewater and utility networks. It uses a pulsed constant-field measuring principle with a conical measuring pipe and is supplied as a separated (remote) version, with the transmitter mounted away from the sensor for easy access on buried or hard-to-reach installations.
