1. Flow Meter Installation
Wafer Style Meter Installation
Install the Dura Mag between two anged end pipes.
Hardware and gaskets are provided, but customers must
supply the anged pipe ends.
Remote Mount Installation
You will need to prepare the location where you will install the remote converter. The location cannot be further from the
ow meter than the length of the 25’ cable. This must be planned in advance because the cable cannot be lengthened.
Doing so will alter the calibration accuracy between the meter and the converter and void the warranty.
Install the ow meter as required. Mount the converter and connect the cable to the meter’s junction box and the
converter’s external connection.
Flanged Meter Installation
Install the Dura Mag ow meter inline between two anged end pipes. The ow meter may require grounding, depending
on the environment they are being installed in. Refer to section 4for a full description of grounding methods that are
available.

Attaching conduit directly to the enclosure may
introduce dangerous gasses and moisture into
the enclosure creating a dangerous condition, and
will remove the enclosure’s IP67 rating. Damage caused
by attaching conduit to the enclosure or altering the
enclosure in any way is not covered by the warranty.
IMPORTANT: Do not cut or alter the cable length
on power or signal cables!
Connections to the sensor must be made with cable
supplied by McCrometer specically for that purpose. Do
not substitute the supplied cable with other types of cable,
even for short runs. For repairs or added lengths of cable, the
entire cable between the sensor and the converter must be
replaced. (Consult factory for replacement cable.)

Mounting the ProComm GO Converter
Note: This applies to the remote mount converter only.
If possible, mount the converter in an electronics shed or environmental
enclosure. The sun shield should be oriented in a direction to reduce sun
damage and ensure readability.
Mount the converter to a solid surface using four bolts. This electronic unit
is rated IP67 for temporary ooding.
2. Remote Mount Converter Installation
Installing Cables through Cable Glands and Conduit
All electrical cables enter the converter through compression ttings or
optional customer-supplied conduit located on the side or bottom of the
converter. Ensure that all compression glands are properly tightened and
all unused ttings are plugged so the case remains sealed.
The power cable and wiring harnesses are each assigned specic cable
glands where they will pass through into the converter. See section 3for
cable gland assignment for wiring harnesses and wiring diagrams.
All cable compression glands must be properly tightened to prevent
moisture intrusion and maintain the IP67 rating. To insure IP67 rating, use
only round cable 0.24”to 0.47”in diameter.

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 uid 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.
