1. Flow Meter Installation
New Installations
Saddle type meters oer simplicity of installation. A
minimum round hole size of 3" should be cut into the top
center of the pipe. The saddle meter is then installed as
follows:
1. Loosen and remove the nuts and washers from the
straps. Remove the straps from the saddle.
2. Cut or hole-saw the pipe and remove all burrs, slag, and
rough edges from the inside and outside of the cutout
section.
3. Place the meter assembly on the pipe with the at
gasket on the 4" models, and the “D” shaped ring
gasket for larger meters in position on the bottom of
the saddle. The saddle must be positioned so that the
at gasket or D-ring maintains contact with the surface
of the pipe completely around the cutout opening.
4. Insert the meter probe through the hole and slide the
meter forward (downstream) until the probe contacts
the front edge of the pipe wall. Then slide the back
away from the pipe wall 1/8" to 1/4" leaving the probe
in a free state and not in contact with the pipe wall.
Replacing Existing Saddle Meters
The Mc Mag3000 can be used to replace existing McCrometer
saddle meters. The Mc Mag3000 can be installed with Water
Specialties bolt-on saddle meter cutout templates for 6”
meters and 8”-20” meters, as well as with McPropeller bolt-
on saddle meter cutout templates for 12”-16”OD pipe.
WARNING! Customers are warned that the
U-Bolt nuts are to be tightened evenly to
approximately 30 foot pounds torque. This is
sucient to seal the saddle to the pipeline. Additional
tightening may be required to seal the saddle on rough
or irregular pipe (60 FOOT POUNDS MAXIMUM).
Important! Insure that the meter probe is not in
contact with the pipe wall when installed!
5. Install the straps from under the pipe and insert the
threaded ends through the holes in the brackets on the
side of the saddle.
6. For each strap bolt, replace the washers and nuts.
7. Tighten each of the U-bolt nuts evenly.
The meter CANNOT be installed with Water
Specialties bolt on saddle meter cutout
templates for 4” meters.

NOTE
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.

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 4.

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.

External Output Connectors
The ow meter is congured at the factory for the optional
outputs and requested by the customer at the time of order.
The external cables attach through a permanent cable gland
(standard) or through a screw locking-type waterproof
connector (quick connect option).
3. Converter Wiring and Connection

IMPORTANT:
When not in use, always keep the attached cap
rmly screwed into the connector to insure a
water-tight seal. Also, keep the contacts in the cable
connector clean and dry during assembly.

The Mc Mag3000 is tted with a grounding lug on the
saddle for proper grounding. For typical installations the lug
can be connected to an earth ground and/or the metal pipe
in which it is installed.
For electrically noisy installations connect the grounding
lug to a dedicated, low impedance earth ground. Low
impedance is 10 Ohms or less.
The grounding lug

5. Activating The Display
The Dura Mag 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.
The display is activated when the lid is opened. The display
will remain active for 30 seconds. The various parts of the
interface screen is shown below.
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.
