Vendor : Changede Water Meter

Overview
Description
Specifications
Applications

Measures water flow, uses wireless communication to connect to local or wide area networks allowing remote location monitoring and infrastructure maintenance

1.Data transmitted through GPRS, safe and reliable 2.The mechanical & electrical separation structure, easy maintenance & replacement 3.The design of double Hall sensor can realize the forward and backward metering of water meter, ensure the complete synchronization of mechanical & electrical separation type, and there is no accumulative error. 4.Long time battery life, 6 years ; 5.Report magnetic interference, low voltage, abnormal alarm to meter reading platform
