[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. When selecting 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. It is suitable for homes, small businesses, industrial sites or field engineering sites.

Due to the above structure, the utility model has the advantages of being able to read at any angle and achieving high efficiency and high precision measurement purposes compared with the prior art.

[0005] Although the above patent has the advantages of being able to read at any angle and achieving high-efficiency and high-precision measurement purposes; however, the device is not equipped with an anti-freeze structure, and cannot prevent ice from forming inside the water meter in winter, and cannot protect the water meter from freezing or damage.

Then the staff will start the electric control valve according to the preset water flow rate to make part of the water in the water meter body flow into the U-shaped tube, thereby controlling the water flow rate, which is beneficial to relieve the water pressure in the water meter body, reduce the impact of water pressure on the internal parts of the water meter body, and extend the service life of the water meter body.

[0021] 2. The water meter with antifreeze effect rotates the brush through the setting of the protective mechanism until the brush loosens the dust and dirt adhered to the surface of the display screen, opens the cover body, blows away the loosened dust and dirt, and then rotates the cover body, which drives the silicone strip to rotate together until one side of the silicone strip is attached to the top surface of the receiving shell, so that the display screen is blocked, avoiding unclear or unreadable display screen readings caused by dust and dirt adhered to the display screen during placement, so that the display screen reading effect is better.
