Water meters are classified by flooding conditions
According to whether the counter is immersed in water, it is divided into wet water meter, dry water meter, and liquid-sealed water meter.
(1) Wet water meter: the water meter whose counter is immersed in water, its glass is subjected to water pressure, and the transmission of the sensor and counter is gear linkage. After a period of use, the quality of the water will affect the clarity of the water meter reading.
(2) Dry water meter: a water meter whose counter is not immersed in water. The sensor is structurally isolated from the chamber of the counter. The glass of the water meter is not subject to water pressure. The transmission between the sensor and the counter is generally driven by magnetic steel.
(3) Liquid-sealed water meter: the meter wheel used for meter reading or the entire counter is made up of a liquid-sealed water meter with a certain concentration of glycerin, etc. The clarity of the sealed and isolated counter is not affected by the external water quality, and the rest of the structural performance is consistent with Same for wet water meters.
