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