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.
