Workers are testing non-residential water meters
In the water meter testing center of the Municipal Waterworks Company located in the courtyard of the Dongyuan Waterworks, a dozen staff are testing and calibrating the new water meters with advanced equipment and sophisticated instruments.
Wang Jun, the squad leader of the testing center, briefly introduced the process of water meter testing to reporters. First, put the water meter into the calibration device, and then verify the water meter by opening the water gate. For unqualified water meters, it is necessary to debug and record the detected values in detail.

A person in charge of the Metrology Section of the Water Meter Testing Center said that the daily testing volume of the water meter testing center is about 200. If it is a peak period, the staff will work longer hours to improve efficiency. “Water meters all have a lifespan, and errors will occur after a long time of use. Therefore, the detection period of general civilian meters is about 6 years, and the detection period of non-civilian meters is 2 years.” The person in charge said that accurate water meters not only It can protect the interests of users, and also protect the economic benefits of the water company.
It is understood that in order to reflect the real water consumption, the sales department of the municipal water company not only strengthened the management of water meters, but also implemented strict checks on the replacement of non-civilian water meters.
