[0002] A water meter is an instrument for measuring water flow, most of which measure the cumulative flow of water. It is generally divided into two categories: volumetric water meters and velocity water meters. It originated in the UK and has a history of nearly two hundred years. When choosing the specifications of a water meter, you should first estimate the size and range of the flow rate normally used, and then choose the water meter with the specification that is closest to the commonly used flow rate as the first choice.
[0003] The pipe joints on both sides of commonly used water meters are generally live joints, which are convenient for maintenance of the water meters. However, they also bring unsafe factors to the use of water meters. Some users illegally dismantle and remove the water meters on their own to reduce their water bills, resulting in the water meters being unable to perform their metering functions, thereby causing economic losses to the water supply department.
