The principle of action of the rotary water meter is; water enters the case from the water meter inlet, through the water filter, enters the impeller box by the inlet hole of the impeller box, impacts the impeller, the impeller starts to rotate, the water then flows into the pipe by the upper outlet hole of the impeller box through the case outlet, the lower part of the impeller is supported by the thimble. After the impeller rotates, through the central shaft of the impeller, the central gear in the upper part also rotates, driving the transmission gear in the impeller box to rotate according to the speed ratio, driving the pointer on the dial. The triangular pointer starts to rotate and then drives the other gears and the upper pointer in a decimal transfer, which starts to rotate in a clockwise direction in accordance with the index value on the dial, starting from 0 and starting to measure.
