When selecting the type of water meter, it must be properly selected according to the user's water consumption, water quality, water pressure and pipe diameter. For example, when the user's water consumption and flow rate change little, it is recommended to choose a rotor type water meter with a diameter smaller than 40mm; If the user's water consumption is large, it is recommended to choose a screw type, water meter with diameter greater than 50mm; If the water quality is turbid, it is recommended to use the counting machine parts of dry water meter and water isolation. If the water temperature is lower than 30 degrees Celsius, water meter is recommended; If the water temperature is higher than 30 degrees Celsius, hot water meter is recommended.
The daily maintenance work mainly includes the following aspects: whether there is any leakage in the joints of each parts of the water meter, and if there is any leakage, it should be handled immediately; Whether the water meter runs normally and whether the sensitive hands rotates; whether the glass of the water meter needs to be cleaned and wiped so that it does not hinder the normal reading; Large diameter water meter for measuring raw water and water meter containing suspended substances and impurities, the stuffing filter and strainer installed at the front end of the water inlet should be thoroughly drained and cleaned.
