Introduction
Strengthening water intake management is an important part of implementing the control of the total amount and intensity of water resources consumption and strengthening the rigid constraints of water resources. Water meter
Quantity is an important content and means of water resources management. It is the implementation of management systems such as water abstraction licenses, water resources tax collection, and water use statistical surveys.
The important basis and main basis for water resources management rights.
This document is based on the relevant content of GB/T 28714-2012 measurement methods, and adds the selection, installation and adjustment of measurement facilities (appliances).
Testing, acceptance, as well as requirements for measurement files, instrument calibration and data management, etc., to adapt to water resources management and water metering supervision
