Direct Reading Remote Transmission Dry Water Meter Valve Control
Function:
1.Zero Error: Using the unique coding technology, the sensor directly reads the wheel position of thecounter.Afterdecoding, the data is transmitted to the system and display the same value as the water meter window shows. Reading difficulties and errors will not caused by time and environment. The system data is exactly the same as the data of basic water meter that is realizing zero error real-time meter reading;Item | Unit | Parameter | ||||
