Optical remote transmission direct reading dry valve controlled water meter

Functional Features

The optical remote transmission direct reading valve-controlled water meter is equipped with valves and control programs based on mature optical direct reading water meter technology, achieving remote meter reading and remote control. It is currently the most ideal water meter for truly realizing intelligent management of urban water supply by various water supply enterprises. In addition to having all the characteristics of optical direct reading water meters, it can also achieve the following features on the upper computer:

1. Automatic valve closure for overdue payments, and automatic valve opening after recharge.

2. Automatic group opening and closing of valves.

3. Individual control of the valve for a specific user's water meter.

4. The intelligent electronic unit is completely sealed within the counter, isolated from water, and not affected by external water and moisture.

5. Communication protocols: DL/T645, CJ/T188, MODBUS, industry standard or user-specified protocol.

 Implementation standards: GB/T778.1~3-218 "Measurement of water flow in closed full pipelines for drinking cold water meters and hot water meters."

                    CJ/T 224-2012 "Electronic remote transmission water meter."
