Begin by calculating the eort that will be required to hold the meter. Establish adequate footing for this task, taking
extra caution when working from a ladder or platform. Use the following formula:
E=0.11 x P Where: E = eort in pounds
P = system pressure in pounds per square inch
Example: In a 300 PSI system, 33 pounds of eort is required to insert the meter into the pipe.

Step 2:
Slowly open the
valve to the full
open position.
Step 1:
Maintain a rm grip
on the enclosure
to counteract
the eects of the
pressure in the pipe.
Step 4:
Orient the enclosure so that the alignment
arrow is pointing in the direction of ow and is
parallel with the pipe.
Step 3:
Use the end of the depth gage to pierce
any insulation that may be present and rest
the gage on the outside wall of the pipe. If
unable to pierce the insulation jacket, you
will have to adjust depth to account for the
insulation thickness.
Step 6:
Carefully tighten
the clamping
nut. DO NOT
OVERTIGHTEN.
Step 5:
Slowly push down
on the ow meter
until the bottom of
the alignment arrow
rests on the top of the
depth gauge.
3.3 INSERTION OF THE METER
WARNING
SYSTEM MAY BE UNDER HIGH PRESSURE. When adjusting the meter position or removing it, be sure to hold the
electronics enclosure rmly by hand before SLOWLY loosening the positioning clamping nut. Failure to do this will
allow the pressure to suddenly and rapidly force the meter from the pipe causing serious injury. The meter could
also be damaged or break apart causing a break in the water seal with the resultant loss of large amounts of water.
The hand eort required to hold the meter will be 0.11 times the pipe pressure.
