Water meter according to the pressure used

Water meters can be divided into ordinary water meters and high-pressure water meters according to the pressure used. High pressure water meters are suitable for high-pressure water supply systems. High pressure water meters are mainly used for high-pressure water supply or injection environments such as underground water injection in oil fields and coal seam water injection in coal mines.
Classified by pressure level, it can be further subdivided according to specific nominal pressures (such as 1.6MPa, 2.5MPa, 4MPa, 10MPa, etc.). Classified by application field, it mainly includes high-pressure water meters for oilfield water injection and high-pressure water meters for coal mines. Classified by connection method, the common ones are flange connections. According to the principle of measurement, it is mainly classified as speed type (impeller type) water meters, which use the principle that the rotational angular velocity of the impeller is proportional to the flow velocity for measurement.
