一、Product Summary

Dear users, thank you for using our multi-flow dry  water meter. Please read this instruction manual carefully before using it, so that you can easily use our products.

Multi-flow dry valve-controlled water meter is mainly a water inlet direction, through which water flows into the water meter movement and scours the impeller of the water meter, thus obtaining a kind of water meter for measurement.

The counter adopts dry counter, which can keep clear reading for a long time. Choose high-quality materials, reliable performance, small initial flow, high measurement accuracy, beautiful and durable appearance; Magnetic sensor is adopted, which has stable performance and high reliability.

However, it also has disadvantages. Because the stress points of a stream of water are relatively concentrated, the impeller of the water meter will be worn to some extent after long-term use, thus affecting the measurement and service life of the water meter.


二、Working Principle

The working principle of the rotor-type multi-flow dry valve-controlled water meter is that the water flow tangentially impacts the impeller from the water inlet of the watch case to make it rotate, and then continuously records the number of revolutions of the impeller through the gear reduction mechanism, thus recording the cumulative flow through the water meter.
