Badger Meter Series 4000 Sensor - 1/2, 3/4", 1" - Manual (Page 7)

ELECTRICAL INSTALLATION
The Series 4000 digital transmitter is supplied with 20 feet of 20 AWG three conductor cable with drain wire and shield. The
Series 4000 analog unit is supplied with 30 inches of cable. Make electrical wiring connections according to accepted trade
practices.
An electrical junction box may be attached directly to the sensor electronic module, or mounted in the vicinity of the sensor.
Locate it conveniently to facilitate replacement of the electronic module assembly. The wiring connections should not be
subjected to water of conductive liquids, as these may impair operations or damage the sensor circuitry.
When connecting to the electronic device, observe the wire colors and polarity to insure proper performance and to prevent
damage to the sensor or electronic device.
