What should be paid attention to when installing water meter?
Direction: position: the water meter can only be installed on the horizontal pipe, keep the dial level, and make the water meter shellThe arrow is in accordance with the direction of the flow. Do not install the arrow. Water meter should be installed before and after the valve, for the water is not allowed or not eliminatedThe pipeline construction shall also be provided with a by-pass pipe where the check valve shall be fitted at the back of the water meter and the valve on the bypass pipe shall be providedSeal.
Connection mode: DN = 40, with screw connection; when DN is greater than 50, with flange connection.
Pipeline decontamination: before the water meter is installed, it should first remove the dirt from the pipe so as not to clog up. It is better to install it before the water meterFilter。
Make sure the installation site is: water meter is installed in view, convenient, free from exposure, cold and non polluted,A water meter generally introduced into a pipe is mounted in a chamber, an external well, a well, a basement or a private room. Small water meter for household useOn the inlet manifold of each production. Water meter should be preceded by the valve, water meter shell from the wall may not be greater than 30mm, water center from anotherA wall (end) distance of 450 ~ 500mm, the installation height of 600~1200mm. To ensure the measurement accuracy of water metersIndeed, the upstream end of the screw wing type water meter shall have a linear pipe section of 8~10 times the nominal diameter of the water meter, and other types of water meters shall be front and rearA straight line section of not less than 300mm. When the length of the straight pipe before and after the water meter is larger than 300mm, it is applied beyond the pipe sectionHead led to the wall, along the wall laying, the center of the wall from 20 to 25mm.
Choose water meter: according to the diameter of pipe, flow rate, choose the corresponding specifications of the water meter, avoid excessive load and damage. waterTable specifications for the nominal diameter of its interface, generally in accordance with the nominal diameter of the pipe to configure the water meter, will not flow more than its maximumFlow rate.
