Final calibration and double check
Connect the test gauge to the top 5 GPM port. With needle valve opened, turn on top control valve. Flow meter
should read 5 GPM. Turn needle valve in to pressurize system to 1500 PSI and note the flow meter. You should
not see more than 1/ 2 a GPM drop. (4 1/2 GPM flow) the bottom 5 GPM port will be tested in the same manner.
(Using the bottom control valve)
If the bottom 5 GPM port reads any less than 4 1/2 GPM, then you will have to recalibrate the 00141-01 flow
control valve. Loosen jam nut and very slightly turn adjustment nut clockwise and tighten jam nut. Remove the
gauge and turn valves on and off, connect it to the 10 GPM port. If it goes on easily, adjustment is complete.
Move the gauge to the 10 GPM port and turn both control valves on. Flow meter should read 10 GPM turn needle
valve in to pressurize system to 1500 PSI and note the flow meter. You should not see more than 1/2 a GPM drop.
(9 1/2 GPM flow)
This completes the calibration procedure. If any problems are encountered, please contact Pandrol for technical
service.
