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.
