Vertical water meter installation method, how to install vertical water meter?
Vertical water meter installation method
(1) Ensure that the front and rear of the water meter have a long enough straight pipe section. The installation position of the water meter cannot be too close to the wall. This is especially important for the horizontal screw-wing water meter. There should be no less than 10 times the diameter of the water meter. , the back of the meter should be no less than 5 times the diameter of the water meter. If the valve in front of the water meter is directly connected to the water meter, the influence of the valve opening on the error of the water meter value is extremely obvious. The distance between the water meter shell and the wall is 10-30mm.
(2) For the installation of water meters, direct sunlight and erosion of harmful gases and liquids should be avoided, and antifreeze measures should be taken.
(3) The environment where the water meter is installed should be clean and tidy, and it is easy to verify and read the meter and remove and replace the water meter. Before the water meter is installed, the debris in the pipeline must be removed.
(4) The installation direction of the water meter and the direction of the arrow on the case should be consistent with the direction of the water flow in the pipeline.
(5) The newly installed pipeline should first remove impurities such as stones, sand, and hemp in the pipeline. If the water quality is poor, a filter should be installed in front of the water meter, and the filter should be cleaned regularly.
(6) During the use of the water meter, the wear, corrosion and other wearing parts of the parts should be repaired in time, and the technical supervision department should be checked regularly. According to my country's water meter verification regulations, the water meter verification period is generally two years.
