Require high GPRS signal intensity
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.

INTRODUCTION ABOUT SHANGHONG
As the China's leading smart water metering system provider , we have developed a compre-hensive water meter and the smart metering system range for the Domestic market, Commer-cial,Agriculture and Industrial . Moving with the changes in lOT technology and more higher precision metering, we are adding more research cost on reduce NRW (Non-Revenue water), improve the high-efficiency using on water.
Today, we have many partners from all over the world with long time cooperation. Since 2019, for providing much more better services, we have started to go abroad, investigating local water metering markets, start some pilot projects and visiting our regular and new customers and for provide better products and services.
We never can't forget the mission from S.H.Meters" To be the leader for water metering system in abroad market". In future, we will do more in water saving, precision metering and intelligent control of water management.
