WARNING!
Insure that the line is depressurized
before beginning installation!
Incorrect installation or removal of meters
can result in serious injury or death. Read
the instructions in this guide on the proper
procedures carefully.
• Any person installing, inspecting, or
maintaining a McCrometer owmeter
should have a working understanding of
piping congurations and systems under
pressure.
• Before adjusting or removing any meter,
be certain the system has depressurized
completely.
• Be careful when lifting meters. Meters can
cause serious injury if lifted incorrectly or
dropped.

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 center of the saddle as shown
below. In a typical installation to achieve ±2%
accuracy the McMag2000 ow meter should be
installed a minimum of ve diameters upstream
from most ow disturbers and two diameters
downstream of the meter, or when used with a
ow straightener, 1.5 diameters upstream and 1
diameter downstream. (Figure 2)
Figure 2. Pipe Run Requirements
Flow Direction
Figure 1. Flow Direction
It is very important to install the ow meter
relative to the ow of the water. The sensor
must face the ow direction
in order for it to make proper
measurements. (Figure 1)
Proper meter installation is the rst step to
ensure excellent meter performance. Follow
these instructions closely. Consult an authorized
service representative or the Factory for any
circumstances encountered which are not
covered in this guide.
All McCrometer products are tested and
inspected during manufacture and prior to
shipping. An inspection should be performed
at the time of unpacking to detect any damage
that might have occurred during shipment.
• All magnetic ow meters are calibrated for a
full pipeline only; if less, the owmeter will
over-measure the ow.
• Although a minimum line pressure is not
necessary for an accurate measurement, a
full pipe is necessary.
• With the meter installed, check the rate-of-
ow indicator. It should be stable to the point
that it can be easily read. Some indicator
movement is normal due to variations in ow.
Erratic movement of the indicator is normally
caused by ow variations and the system
should be checked. Drastic variations in ow
can decrease meter accuracy. If you suspect a
problem with the meter, please contact your
local McCrometer representative.

The McMag2000 has been designed for easy replacement in the eld for Mc Propeller ow meters. When
the existing saddle meter has been removed, follow the basic installation instructions above. The
replacement ow meter will be fully assembled and ready to install.
The McMag2000 is a saddle type meter. It may be
installed directly onto an existing pipe. Follow
these steps for a new ow meter installation.
1. Cut or hole-saw a round hole minimum 3” in
diameter in the pipe and remove all burrs,
slag, and rough edges from the inside and
outside of the cutout section.
2. Loosen and remove the nuts and washers
from the straps. Remove the straps from the
saddle.
3. Apply lubrication to the gasket and inner
diameter of U-bolts with MolyKote lubricant
or equivalent.
4. Place saddle with gasket in place over the cut
out.
5. Place U-bolts underneath the pipe and
through the saddle clips.
6. Place the provided washers and nuts on the
U-bolts that have been installed through the
saddle clips.
Replacing an Existing Saddle Meter
Basic Installation Steps
7. Start tightening down the nuts evenly in a
gure 8 pattern.
7a. Tighten the nuts to 40 ft. lbs. evenly
using a gure 8 pattern.
7b. Tighten the nuts to 60 ft. lbs. evenly
using a gure 8 pattern.
7c. Tighten the nuts to 80 ft. lbs. evenly
using a gure 8 pattern.
8. Go back around and loosen all of the nuts.
Do not back the nuts completely o of the
U-bolts. The goal is to release force and
tension o of the saddle and the gasket.
9. Repeat steps 7a through 7c exactly as
described. Any step that is skipped may
result in an improper seal.
10. Apply pressure/turn on pump.
11. Verify the saddle is not leaking water. If it is,
repeat steps 5 through 7 until the saddle has
sealed.
The McMag2000 should not be connected to any earth ground. Connecting to an earth ground
may adversely aect meter performance.
NOTE
The McMag2000 can be used to replace existing 4”to 16”Mc Propeller saddle meters. The meter
CANNOT be used to replace a Water Specialties bolt on saddle meter.

6. Remove the ProCommGo converter lid by
loosening the four captive screws at each
corner until the lid can be lifted from the
converter enclosure base.
7. Loosen the two captive screws that secure the
unhinged end of the internal bracket from
the lower converter housing. The internal
bracket (which holds the main circuit board
and battery pack) should now swing freely
over to one side, thus exposing the bottom
of the converter enclosure base, large pass
through and four mounting holes.
8. Place the lubricated O-ring (#3) into the
groove on top of the adapter plate (#4) and
mount the base plate of the ProCommGo
converter onto the adapter plate with the
four mounting screws (#5.1), lock washers
(#5.2), and at washers (#5.3).
9. Insert Ethernet cable assembly (#2) down
through the bushing (#6.1) and ell until the
Ethernet plug end extends 2-3 inches beyond
the threaded portion of the saddle elbow.
10. Plug the cable into the sensor (#7.1).
11. Push the sensor onto the elbow (threaded
end) until the skirt of the sensor has extended
past the rst O-ring. The sensor should stop
against the threads.
12. Screw the sensor onto the ell. Hand tighten
only. Do not cross thread when attaching
sensor.
Refer to Figure 3 and Figure 4 for the conversion procedure.
Removing the ow meter
1. Remove the ow meter that will be converted to an McMag2000.
2. Remove all parts from the saddle. Keep the saddle, U-bolts and U-Bolt nuts/washers. All other parts
will not be used.
3. Connect the adapter plate (#4) to the saddle with the bushing (#6.1), two O-rings (#6.2 & 6.3), and
gasket (#6.4). Ensure to adequately tighten the bushing (>50ft-lbf) to avoid loosening over time.
4. Replace and lubricate the two O-rings (#7.2) on the threaded end of the ell.

The McMag2000 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.
Operation
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.
