1. In order to ensure the most accurate measurement, install a straight pipe section with at least 5 times the surface diameter in front of the water meter inlet and at least 2 times the surface diameter at the water meter outlet
2. The connecting pipes at the upstream and downstream of the water meter shall not be reduced
3. It is recommended to install flow control equipment (such as valves) and filtration equipment
4. The flange sealing ring shall not protrude into the pipe or be misaligned
5. Before installing the water meter, the pipeline must be thoroughly cleaned to prevent debris from damaging the water meter
6. The water flow direction of the water meter should be consistent with that of the pipeline
7. After the water meter is installed, slowly drain the water to fill the pipeline to prevent the high-speed air flow from damaging the water meter
8. The installation position should ensure that the pipeline is full of water, and bubbles will not be concentrated in the meter. It should avoid installing the water meter at the highest point of the pipeline
9. The water meter shall be protected from water pressure impact
10. The small caliber rotor type water meter must be installed horizontally. Tilting back and forth or left and right will reduce the sensitivity
