Begin by calculating the effort 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 = effort in pounds
P = system pressure in pounds per square inch
Example: In a 300 PSI system, 33 pounds of effort is required to insert the meter into the pipe.
3.3.1 Inserting the Flow Meter
WARNING
SYSTEM MAY BE UNDER HIGH PRESSURE. When adjusting the meter position or removing
it, be sure to hold the electronics enclosure firmly 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 effort required to hold the meter will be 0.11 times the pipe pressure.
