Sensor Wiring
All flow sensor types connect to the four terminal
header labeled “sensor input”.
Series 200
Connect the red wire to sensor signal (+), black wire
to sensor signal (-) and the bare wire to shield.
SDI Series
Connect the plus (+) terminal of the sensor to
sensor signal (+) on the transmitter and the minus
(-) terminal of the sensor to sensor signal (-) on the
transmitter. Connect the shield terminal of the sensor
to the shield terminal of the transmitter.
Other Sensors
The sensor input Power Out terminal supplies
nominal 12VDC excitation voltage for 3 wire sensors.
Connect sensor signal + and sensor signal - wires to transmitter terminals.
Temperature Element Wiring
The Badger Meter thermistors are not polarity sensitive.
Connect thermistor closest to the flow sensor to Series 340
terminal block marked TEMP 1 and the other thermistor wires to
Series 340 terminal marked TEMP 2.
