[0002] Water meter is an indispensable instrument in modern life. It is an instrument for measuring water flow. It is generally divided into two types: volumetric water meter and speed water meter. and the flow range, and then choose the water meter with the specification that is closest to the value of the common flow as the first choice. In winter, due to the characteristics of water shrinking with heat and expanding with cold, when the temperature is low, if the water passing through the water meter freezes, It is easy to cause the water meter to freeze and crack, which brings a lot of inconvenience to daily life
