3 . Sensor grounding for meters with minimal ground noise
Attach the provided 12 gauge wire, or equivalent, to the sensor ground lug. Then connect this sensor ground lug to an
earth ground point. (Figure 17)

2 . Sensor grounding for meters in an electrically noisy environment
If there is electrical noise in the fluid column or electrical current in the pipe, it can be minimized or eliminated using
grounding rings or by grounding the pipeline. This applies to meters mated to conductive uncoated pipe.
Attach the provided 12 gauge wire, or equivalent, to the ground lug. Then connect the sensor ground lug to an earth
ground point. (Figure 16)
Next, connect the two mating pipe sections with a 12 gauge wire or equivalent and connect them both to the earth
ground. The Dura Mag should be electrically isolated from the pipeline.
