ELECTRICAL INSTALLATION
Disconnect power from flow sensor source and/or receiving device prior to any installation or maintenance
of the system.
Flow sensor source and/or receiving device must provide basic isolation from mains to insure safe operation
of the system.
General
The sensor leads are supplied with watertight caps over the ends.
1. DO NOT remove the plastic caps from the sensor leads until ready to splice. See Application Brief DAB-031 and Technical
Brief DTB-043 at www.badgermeter.com.
2. Use a twisted pair cable suitable for direct burial to connect the sensor to the endpoint, monitor, or controller. Multi-pair
telecommunication cable or direct burial cables may be used.
3. Make a water tight splice. Two part epoxy type waterproof kits are recommended. Be sure the epoxy seals the ends of the
cable jacket.
4. Make sure the epoxy is hardened before inverting the splice or dropping it in standing water.
5. DO NOT make an underground splice unless absolutely necessary.
6. Route the cable from the sensor to a Badger Meter flow monitor/endpoint. The cable may be extended up to 2000 feet,
using 2-conductor shielded 20 AWG or larger stranded copper wire with appropriate ratings. Be sure to leave enough
flexibility in the cable or conduit to allow for future service of sensor, if necessary.
7. When connecting to a Badger Meter flow monitor/endpoint, locate the section of terminal strip on the monitor
labeled SENSOR INPUT or SENSOR. Connect the red wire to IN, SIGNAL(+) OR SIGNAL terminal and the black wire
to GND, SIGNAL(–), or COM terminal and the shield drain wire (if applicable) to SLD.
8. When interfacing with other equipment, the signal wave forms and power requirements are as shown in
"SPECIFICATIONS" on page 10. Refer to Technical Brief DTB-058 at www.badgermeter.com.
