Photoelectric remote direct reading dry- dial valve control water meter

Features

 Photoelectric remote direct reading valve control water meter is made by adding valve and control program to the mature photoelectric direct reading water meter skill, in order to achieve remote meter reading and remote control. It is now the most ideal water meter for water supple enterprises to realize smart management of water supply in cities. besides all the features of photoelectric direct reading water meter, it can achieve following features in master computer:

  1.Close the valve automatically when arrears, and open it automatically after recharging.

  2.It can realize group on and off.

  3.It can switch the valve of some user alone.

  4.Intelligent electronic unit is sealed completely in the counter, isolated from water, free from the erosion of external water and moisture. 

  5.Communication protocol: DL/T645, CJ/T188, MODBUS, industry general statutes or others appointed by users.

 Execution standards: GB/T 7 78.1-2007“Measurement of water flow in fully charged closed .

conduits- Meters for cold water and hot water",
