What's wrong with Ann's new water meter? Can you get back after reinstalling?
A water meter is an instrument for measuring water flow. The cumulative flow of water is mostly measured. Generally divided into the volume of water meters and speed water meter two categories. The accuracy of the former is higher than that of the latter, but it requires high water quality and is easily blocked when the water contains impurities. An instrument for recording the amount of water used in running water is mounted on a water pipe, and when the user leaves the water, the pointer or wheel turns on the table to indicate the amount of water passed.
The water meter can operate both positive and negative, and when the meter is proofread the water meter, it is also tested in both positive and negative directions.
