1. Flow Meter Installation
New Installations
Saddle type meters oer 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
sucient 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
