GPRS WATER METER
Caliber-DN15~25

Brief introduction
GPRS wireless water meter belong to high-tech smart water meter, using of advanced wireless transmission technology. It transmission metered information of conventional mechanical water meter to cloud server via GPRS.
Automatically read the metering data via wireless remote network and control the close / open of the valve, and is also able to transfer the data to the back-office system (data center) after reading the meters by wireless handset reader.
Benefits
·With anti-magnetic interference function.
·With the battery voltage detection function.
·Module with automatic data storage function when power down arises, assuring the data won’t lost when power down.
·The joint of the GPRS module and the base meter uses the integrated structure, with built-in antenna, reducing the damage of antenna during the process of installation;
·Using GPRS transfer mode that can drastically extend the communication.
·The module uses of deep dormancy time design, it is able to completely close the wireless module during the deep dormancy time period(not in operation during night time ), which drastically help reduce the power dissipation;
·Whole circuit board uses of ultra low power consumption design, power supply by high capacity lithium battery, battery life over 6 years;
·Set up the metering devices by the handset reader and check the original data and data from meter reading;
·Wide area network, no installation distance and water meter quantity limit.
