1.0 DESCRIPTION OF THE FLOW METER
The Dura Mag ow meter combines the proven full bore magnetic ow sensor with a battery powered electronic converter
package to provide accurate ow measurement in tough, remote applications.
The Dura Mag ow meter uses Faraday’s Law of Electromagnetic Induction to measure water velocity. Faraday’s Law states:
A conductor, moving through a magnetic eld, produces a voltage. Charge carriers in the uid produce a voltage when
passing through a magnetic eld. The magnitude of the voltage is directly proportional to the velocity at which the uid
moves through the magnetic eld. Electromagnetic coils inside the sensor produce magnetic elds, and electrodes on the
sensor’s surface measure the voltage generated by the moving uid.
The anged end tube and wafer style designs permit use in a wide range of applications and are available for pipe sizes
from 2 to 12 inches. The converter is powered by lithium batteries that can provide ow measurement for an estimated ve
years (battery is covered by warranty for that period). Also available is the optional DC power supply (required for 4-20mA
output). The ow meter has optional pulse, 4-20mA, and AMI outputs available. All Dura Mag ow meters have an internal
datalogger standard. the optional datalogger software and cable is required to retrieve the stored data.
2.0 UNPACKING THE CRATE AND VERIFYING SERIAL NUMBERS
2.1 Uncrating
The shipping crate contains the following items:
• Electromagnetic meter assembly with grounding stud attached
• Converter cable (attached to meter)
• Signal converter
• Grounding rings
• Ground wires (2)
• User manuals for both the sensor and converter
• Installation hardware (2”& 3” only)
• Gaskets (4) (2” & 3” only)
When uncrating the Dura Mag, any damage due to rough or improper handling should be reported to the transportation
rm and McCrometer. If for any reason it is determined that the unit or parts of the unit should be returned to the factory,
please contact McCrometer for clearance prior to shipment. Each unit must be properly crated to prevent any further
damage. The factory assumes no responsibility for equipment damaged in return shipment due to improper packaging.

3.1 Sensor Location
Adjoining pipe must be adequately supported, and the
area around the sensor should provide sucient drainage
to prevent ooding the converter or conduits. The location
chosen should provide room to read the display and be free
from harsh electrical noise from adjacent equipment, cables,
RFI, or EMI.

3.2 Pipe Run Requirements
Flow meters are velocity sensing devices and are vulnerable to certain upstream disturbances. Because of this, meters
need certain lengths of straight pipe before and after the meter. These distances relate to the diameter of the pipe
used. Obstructions can include elbows, valves, pumps, and changes in pipe diameter. The uneven ow created by these
obstructions can vary with each system.
Both upstream and downstream distances are measured from the end of the ange as shown below (Figure 1).
3.3 Positioning and Orienting the Sensor
The following installation recommendations should be followed (see Figure 2 for installation diagrams):
Figure 2. Sensor orientation options
Flow direction
Flow direction
Horizontal installation
In horizontal pipe runs, the meter should be installed so that the
junction box is vertical insuring the electrodes are positioned
to prevent coating by sediments or loss of electrode contact
due to air bubbles.
Fluid level
Flow direction
Less than full pipes
In pipes which may encounter less than a full
pipe of uid, the meter must be positioned
in a trap to ensure that the sensor is always
completely lled with liquid.
Fluid level Fluid level
Flow direction
Vertical installation
In vertical pipe runs,
the ow should be
upward. In slurry
application, a vertical
position ensures
optimal distribution
of solids under all ow
conditions.

4.0 FLOW METER INSTALLATION
4.1 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. (Figure 3)
The ow meter may require grounding, depending on the
environment they are being installed in. Refer to section
7.1 for a full description of grounding methods that are
available.
4.2 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 7.1 for a full description of grounding
methods that are available.
The ow of the medium should correspond to the direction shown by the arrow on the sensor.
Figure 3. Wafer style meter installation
Shown are customer’s
pipe ends and anges
NOTE
I
NOTE
Nothing in this manual supersedes local codes.
4.3 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 described in section 4.1 or section 4.2. Mount the converter and connect the cable to the meter’s
junction box and the converter’s external connection. Figure 4 below shows an example of a remote mount installation
with an optional Smart Output connection.

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.)

5.1 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 (Figure 5). This
electronic unit is rated IP67 for temporary ooding.
5.2 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 (Figure 6 and Figure 7). 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 6.2
for cable gland assignment for wiring harnesses and section 6.4 for 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.

Information For Grounding Ring Installations
• Gaskets must be used on either side of the grounding ring to provide a proper seal on the anges. One
gasket is used on anges without a grounding ring.
• Rings & gaskets must align concentrically with the pipe so they do not obstruct or aect ow through the
tube.
• The two grounding rings and four gaskets require an additional installation width of 0.375”.
Always ensure that the converter and the sensor are grounded (earthed) correctly. The grounding of the sensor and
converter ensures that the equipment and liquid have an equal potential. For most installations the quality of grounding
by the provided cabling assures the sensor is properly grounded and additional grounding of the sensor is not required.
However, in instances where this is not the case, i.e. the equipment and uid do not have an equal potential, such as where
the installation location and/or media is subjected to electrical interference, additional grounding steps may be required.
Consult an electrician experienced with instrumentation installations to determine if electrical interference is present.
7.0 GROUNDING AND ELECTRICAL INTERFERENCE

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. (Figure
15)
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.
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.

7.1 Sensor Grounding Methods
All Dura Mag ow meter installations require minimum grounding with a 12-gauge ground wire to an earth ground.
Installation must conform to NEC requirements. Flanges on the Dura Mag sensor have a non-conductive coating and may
not require grounding rings. For best performance, McCrometer can provide optional grounding rings for all sizes.
When installing into a PVC or plastic pipe system, grounding rings are recommended for all sizes.
Three methods of grounding are described in this section:
• Grounding for non-conductive or internally coated pipe (preferred method of grounding)
• Grounding for meters in an electrically noisy environment
• Grounding for meters with minimal ground noise

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. (Figure 16)
Next, connect the two mating pipe sections with a 12 gauge wire or equivalent and connect them both to the earth

8.0 OPERATION
8.1 General
The ow meter comes pre-congured from the factory based on the installation parameters provided to McCrometer at
the time of order. Other than activating the display, there is nothing required of the user for the basic operation of the
ow meter.
Figure 18. Lift lid to activate display
CAUTION:
If the lid is broken o, contact the Factory for a lid
replacement kit. In the meantime, set the lid on the
meter in its proper position and use the boot to hold it in place.
I
The converter display is light activated and requires
a minimum amount of light to appear. Environments
where light is low, such as in dimly lit buildings or
outdoors after sundown may prevent the display from appearing
when the lid is raised.
There is an optical sensor embedded in the display located under
the McCrometer “swirl” logo at the lower left. If the display does
not appear, a ashlight will provide sucient light to bring it up.
NOTE
