Design and functionD184B140U02 FSM4000 172.2 DesignAn electromagnetic flowmeter system consists of a flowmeter sensor and a transmitter. Theflowmeter sensor (model SE41F, SE21W, SE21F, SE21) is installed in the specified pipelinewhile the transmitter (S4) is mounted locally or at a central location.2.3 Device designsThe μP transmitter is mounted at a separate location from the flowmeter sensor. Up to 50 mcable length for a minimum conductivity of 20 μS/cm. For flowmeters with preamplifiers, thesignal length is increased to 200 m. The electrical connection between the transmitter and theflowmeter sensor is provided by a signal cable and a magnet coil cable in the terminal box.Fig. 7The transmitter is available in the design:• Field housing unit model S4The flowmeter sensor comes with aluminum or stainless steel housing:• Aluminum housing: Model FSM4000-SE41F• Stainless steel housing: Model FSM4000 SE21W / SE21F / SE21ImportantAlso older model flowmeters sensor can be connected to S4 transmitters. For additionalinformation, see chapter "6.1 Preliminary checks prior to start-up" or "11 Operating S4 with anolder sensor".
