Next, connect the two
mating grounding rings
with a 12 gauge wire or
equivalent, attached to the
grounding ring lugs, and
connect them both to the
earth ground. The Dura
Mag should be electrically
isolated from the pipeline.
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.
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.
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.
1. Preferred method of grounding
Dura Mag meters come standard with a set of grounding rings for use with the preferred method of grounding Dura Mag
meters.
This method can be used for all installations, but it is required for non-conductive or internally coated pipe. When pipes are
non-conductive, such as PVC or internally coated pipe, you must substitute direct grounding with grounding rings.
Attach the provided 12 gauge wire or equivalent to the sensor ground lug. Then connect this sensor ground lug to an earth
ground point; refer to NEC or local grounding regulations for wiring requirements in making this connection.
