Details description


This water meter uses many of Jingda's own technologies. The base meter is a wet ordinary water meter, and a LoRa intelligent remote transmission module is installed above it to form an intelligent remote transmission water meter.


The technology is stable and reliable, and it is easy to disassemble, assemble and maintain. It is suitable for the renovation of old meters per household and the installation of household meters and water metering and charging needs in new buildings. After-sales management is very convenient and highly user-friendly. It is the preferred IoT water meter for water resources management departments.


Technical features


The base meter complies with the national standard GB/T778-2007 "Drinking Cold Water Meters and Hot Water Meters"

All technical indicators comply with CJ/T 224-2006 "Electronic Remote Transmission Water Meter" standard

Detachable technology facilitates metering, charging, maintenance and replacement by the tap water charging management department.


Low installation requirements: an ordinary wet mechanical water meter is used, with standard dimensions and easy installation;

Easy maintenance: Adopting a detachable design, the "LoRa remote transmission module" is fixed above the base table. The base table and the remote transmission module are easy to disassemble and assemble, and are easy to maintain;

Double battery backup: The remote transmission module is equipped with 1 high-performance battery and 1 backup battery to ensure that the water meter can work normally for ≥ 6 years;

High measurement accuracy: using a wet base meter, the initial flow rate is small, and an anti-drip device can be added;

The technology applied to the entire watch can improve the anti-freezing performance at -8℃;


Real-time reading function is realized through the frequency range of 470MHz~510MHz and LoRa wireless communication method. Transmitting power ≤50mw. The first-level open space communication distance between the concentrator and the water meter is about 1KM. By adding relay routes, the longest meter reading distance is about 5KM.


Battery voltage reading function: Through the remote meter reading platform, battery voltage data can be read every day
