DESCRIPTION OF THE FLOW METER
1.0 DESCRIPTION OF THE FLOW METER
Ultra Mag meters are available with integral or remote mount converters. Standard display features include forward,
reverse and net ow totalizers, ow rate, alarm monitoring, and automatic self diagnostics to ensure integrity. All data and
values are in selectable units of measurement. System compatibility is assured with a choice of current, pulse and serial
data. Please refer to the converter manual provided with your meter.
Ultra Mag operating parameters are set via the electronics keypad. The software features multilevel password protection
capability to prevent inadvertent program or setting changes. Data is stored in nonvolatile memory.
The anged end tube design permits use in a wide range of applications. The fabricated tube is stainless steel with steel or
stainless steel anges and incorporates the UltraLiner, an NSF approved fusion-bonded epoxy liner.
2.0 UNPACKING THE CRATE AND VERIFYING SERIAL NUMBERS
2.1 Uncrating
The shipping crate contains the following items:
When uncrating the Ultra 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.

PREPARING FOR A NEW INSTALLATION
3.0 PREPARING FOR A NEW INSTALLATION
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 Remote Mount Converter Location
The signal converter may be installed in a desired location provided that free access is available to allow the display to
be viewed as required. The unit can be either wall mounted or panel mounted with masonry xings or nuts and bolts
respectively via the xing holes provided. The maximum distance between the meter and the converter is 25 feet. For
applications with extended lengths, consult factory.
3.3 Pipe Run Requirements
The meter needs to be located a minimum distance before and after ow disturbances, such as elbows, pumps, partially
opened valves, and changes in pipe diameter. The uneven ow created by these obstructions can vary with each system.
The following installation recommendations should be followed (see Figure 5 for installation diagrams):
Figure 2. Serial number tag locations for
meter mount and remote mount converters
The serial number tag is located on the side or top of the converter (Figure 2). The tag has the converter model number,
the converter serial number, the meter model number and the meter serial number. Examples are shown below (Figure 3
and Figure 4).

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.
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 METER INSTALLATION
4.0 FLOW METER INSTALLATION
4.1 Wafer Style Meter Installation
Install the Ultra Mag between two anged end pipes.
Hardware and gaskets are provided, but customers must
supply the anged pipe ends.
The ow meter may require grounding, depending on the
environment they are being installed in. Refer to section
8.0 for a full description of grounding methods that are
available.
4.2 Flanged Meter Installation
Install the Ultra 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 8.0 for a full description of grounding
methods that are available.
Nothing in this manual supersedes local codes.
NOTE
The ow of the medium should correspond to the direction shown by the arrow on the sensor.

IMPORTANT: The example shown above does not include grounding
installation. Depending on your requirements, the meter will need to be
grounded according to the methods shown in section 8.0.
Shown are customer’s
pipe ends and anges
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 8 below shows an example of a remote mount installation
with an optional Smart Output connection.

5.1 Mounting the ProComm GO Converter
converter (Figure 10 and Figure 11). 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 5.4 for cable gland assignment for wiring harnesses and section 6.2 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.
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. This electronic unit is rated IP67 for
temporary ooding.
There is a stainless steel mounting plate attached to the back of the
ProComm GO converter, which is used to mount the converter to a solid,
at surface using four bolts (Figure 9). Mounting plate feet are located at
the top, bottom, left, and right sides.
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
WARNING
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.)

GROUNDING AND ELECTRICAL INTERFERENCE
NOTE: On meters installed on a line with cathodic protection it may be necessary to insulate the meter from the
line. Consult your cathodic protection vendor for instructions.
I
8.0 GROUNDING AND ELECTRICAL INTERFERENCE
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.
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”.
I
8.1 Sensor Grounding Methods
All Ultra 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 Ultra 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

1. Preferred method of grounding
Ultra Mag meters come standard with a set of grounding rings for use with the preferred method of grounding Ultra 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

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 Ultra 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. (Figure 28)
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 27)
Next, connect the two mating pipe sections with a 12 gauge wire or equivalent and connect them both to the earth
ground. The Ultra Mag should be electrically isolated from the pipeline.
