INSTALLATION PROCESS METER WATER (WATER METER) 
1 Clean pipe: Before attaching the clock to clean up the foreign object in the pipeline. 
             Source water must not contain solids such as sand, mud, cement ... These are common contaminants when installing new pipelines. 
             2 meter mounting position: Water meters are installed horizontally only. Right hand of the clock upward. 
             3 Connections clock before and after: 
             Length of pipe before and after meter straight right. Pipe section prior to 10 times the minimum length; after a long pipe sections must be at least 2 times the diameter clock.
             All joints bending paragraph, Y, T, 1-way valve or pressure regulator valve etc. .. an impact on traffic flow in addition to installation of pipe specified distance. 
             Valves open fully, couplings and pipe segment not greatly affect revenue flow is also calculated on the length of straight pipe sections front and rear clock. 
             In the case does not meet the standards of the length of straight pipe sections, to ensure correct operation clocks need adjustment pressure valve fitted front and rear clock.
          4 Dimensional Flow: 
             Dimensional flow must be consistent with the direction arrow on the body clock.
