Ways to solve the metering deviation of the water meter:

(1) Renovate the household pipe network and strive to improve the water quality of the pipe network;

(2) Strictly check the water meter in strict accordance with the provisions of the national inspection regulations of the water meter, and make the rotation of the expiration;

(3) When the water meter is selected, the rated flow of the water meter should be as close as possible to the actual water flow rate;

(4) During the installation of the water meter, it must be installed in strict accordance with the technical requirements of the water meter. First, there should be a certain straight pipe section before and after the water meter. The length of the straight pipe section before the watch should be no less than 10 times the diameter of the water meter. The surface should be no less than 5 times the diameter of the water meter. Second, the water gauge should be horizontal; the third is the water meter. It is good to install the filter to effectively prevent the water from entering the water meter. Fourth, the valve should be fully opened before the water meter to make the water pressure stable, so as to ensure accurate metering.
