No Moving Parts, high accuracy for years long. No moving components in the flow sensor, avoid long-term abrasion of mechanical parts which may result in inaccurate measurement and failure of the meter. Such design is also resistant to impurities, therefore no inspections and maintenance are cost-free.

1. switching valves and filters shall be installed upstream of the water meter; it is recommended that switching valves be installed downstream of the water meter for maintenance purposes. A check valve shall be installed upstream or downstream of the water meter to prevent backflow.
- Before using this water meter, the pipe must be filled with water, otherwise, it will lead to inaccurate or even non-measurement;
- When installing the water meter, should be reserved length of DN*10 in front of the water meter. Or should be reserved the length of DN*5 behind the water meter;
- The water meter shall refresh the display every 4s, and read the water meter (including the starting value and end value) 4s at least after the valve is closed when testing the water meter, otherwise, the testing results may be affected;
- The product is designed with a disposable anti-disassembly seal which shall be removed only by appointed personnel, or otherwise, it shall be excluded from the free after-sales service.
