The working principle of a mechanical water meter is based on the hydrodynamic effect: when water flows through the meter’s movement, it drives the impeller to rotate. The rotational speed of the impeller is directly proportional to the water flow velocity (and thus the instantaneous flow rate). This rotational motion is then transmitted and decelerated through a precision gear train, converting the number of impeller rotations into cumulative water volume. Finally, the cumulative volume is accurately displayed via pointers or digit wheels for reading, achieving the quantitative measurement of water consumption.
