The accuracy of meter metering is very important for the protection of the interests of both parties.
1. The water meter selection should conform to the specifications.
When selecting the model for the 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 is small, it is recommended to select a rotary-type water meter with a diameter of less than 40mm. If the user's water consumption is large, it is recommended to use a screw-type water meter with a diameter greater than 50mm; if the water quality is turbid It is recommended to use a dry water meter counting device and water isolation. If the water temperature is lower than 30 degrees Celsius, it is recommended to use a cold water meter; if the water temperature exceeds 30 degrees Celsius, it is recommended to use a hot water meter.
2, Strengthen the production specifications of water meters
The production quality of water meters is an important prerequisite for ensuring the accuracy of water meters. Therefore, it is necessary to strengthen the supervision and management of water meter production enterprises and strictly eliminate the inferior water meters. Moreover, the purchasing company should also insist on purchasing from the regular manufacturers, and the purchased water meter must have a quality certificate and a water meter verification certificate.
3, Water meter specification installation
The standard installation of the water meter is very necessary. In the process of installation, the safety, convenience and reliability of the water meter should be fully considered; the installation of the water meter should be carried out at the straight pipe section of the pipe, and it must be guaranteed to be full pipe operation. . The length of the straight pipe on the side of the water outlet of the water meter shall not be less than 5 times of the diameter, and the length of the straight pipe on the side of the water inlet shall not be less than ten times the diameter of the diameter; before the installation of the water meter, the blockage of the inlet and outlet shall be cleaned to reduce the blockage. Probability; if the water meter is installed outdoors, a protective box must be added, and it cannot be installed in a place exposed to cold or sun exposure. In winter, the anti-freezing measures of the water meter are required; the horizontal installation of the water meter cannot be more than 1.5. Degree, and, to ensure that the word is facing up, its arrow is consistent with the direction of the flowing water; different specifications of the water meter, the installation must also take a different way of working, whether it is the installation orientation, or the straight pipe section of the upstream and downstream must comply with the installation of the water meter Requirements.
4. Strengthen the use and maintenance of water meters
The daily maintenance work mainly includes the following aspects: whether the joints of the water meter parts are leaking or not, and the leakage should be treated immediately; whether the operation of the water meter is normal, whether the sensitive pointer rotates; whether the glass of the water meter needs to be cleaned and wiped, so that it does not Obstruct normal readings; large-diameter water meters that measure raw water and water meters with large amounts of suspended solids and impurities in the water, and thoroughly drain and clean the packing filter and filter installed at the front end of the inlet.
