5.2 Connecting the flowmeter sensor
5.2.1 Connecting the signal and magnet coil cables
The flowmeter sensor is connected to the transmitter via the signal / magnet coil cables (part
no. D173D025U01 / D173D147U01). The coils of the flowmeter sensor are supplied with a field
voltage by the transmitter over terminals M1/M3. Connect the cables to the flowmeter sensor
according to the following drawing, using a screwdriver with proper size and width.
