The operations should be as follows: ( The Graph of The Serial Anti-Pressure Watermeter Checking Platform)
1 Select the socket of the checked watermeter, push forward the valve so that the watermeter will be clamped in the middle.
2 Open the inlet valve, outlet valve, air valve and the finishing pointer valve to discharge all the air in the pipe and the watermeter.
3 Turn around the two-digit four-channel switch to the loose position and the time should no less than 20 seconds. Close the outlet valve and close the inlet valve.
4 Turn the two-digit four-channel switch to the pressurized position. When the pressure in the pipe reaches the set value, turn the switch to the loose direction. Look at the pressure meter and find that the pressure remains stable and then close the finishing valve.
Attention: Turn the finishing valve to a small value when the pressure is increased. Turn the switch exactly when the pressure reaches the requirements.
5 After the anti-pressure process, close the inlet valve and open the air valve to lower the pressure to zero.
6 Disconnect the switch and take the watermeter.
