Description

technical field [0001] The invention belongs to the technical field of material processing and relates to a stainless steel water meter casing. Background technique [0002] A water meter is an instrument that measures water flow. Mostly cumulative flow measurement of water. It is generally divided into two types: volumetric water meters and speed water meters. The accuracy of the former is higher than that of the latter, but it has high requirements on water quality, and it is easy to be blocked when there are impurities in the water. The meter that records the water consumption of tap water is installed on the water pipe. When the user releases water, the pointer or character wheel on the meter rotates to indicate the amount of water passing through. [0003] A water meter generally includes a housing, a cover, and a watch glass. The shell is an important part of the water meter, which is generally divided into cast iron shell water meters, copper shell water meters an...
