A meter that measures water flow. Mostly the cumulative flow measurement of water. Generally divided into two types of volumetric water meters and speed water meters. The accuracy of the former is higher than that of the latter, but the water quality is high, and the water is easily blocked when it contains impurities. The meter for recording the water consumption of the tap water is installed on the water pipe. When the user releases the water, the pointer or the character wheel on the watch rotates to indicate the amount of water passing through.
