2.1. volume: 0.3m3；

2.2.work pressure :0.3- 0.4MPa, test pressure: >0.6MPa,；

2.3.stainless material: thickness:3mm

3,Water tank (option)

3.1. volume: 2m3

3.2. stainless material : thickness≥1.5mm

4, water pump(option)

4.1 Model:KQL80/200-7.5/2 1No Q=43.5m3/h;H=38m;N=7.5kw

1. Turn on the pump

2. Put the METER under test in the verified position

3. Open all valves 1,2,3,4,5,6 to drain the air from the pipe

4. Close valves 3, 4, 5 and 6

5. Read the initial value v1 of the testing meter

6. Manually open one of the valves 3,4,5,6 according to the flow point and adjust to the corresponding flow point

7. Wait for the flow to reach the position of the meter. For example, open valve 3 when verifying Q1, and then wait for the volume to reach 10L.And read the final value V2 of the checked table

8. Read the value Vi on the standard gauge

9. Calculation error
