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.
The McMag2000 can be used to replace existing 4” to 12” Mc Propeller saddle meters. The
meter CANNOT be used to replace a Water Specialties bolt on saddle meter.

To save battery life, always close the lid after reading the display. If the lid is kept open, the
display will remain on, reducing battery life. If the lid is lost, contact the factory immediately
for a replacement.
The McMag2000 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
NOTE
The display is activated when the lid is opened. (Figure 6) The display will remain active for 30 seconds.
The screen will automatically deactivate after 60 seconds. See Figure 7 below for display descriptions
and symbols.
