All technical indicators are in line with CJ/T 224-2006 "Electronic Remote Water Meter" standard
The patent name "a detachable intelligent remote water meter" facilitates metering, charging and maintenance replacement of the water fee management department.
Low installation requirements: the use of ordinary wet mechanical water meters, size standards, easy to install;
Convenient maintenance: The detachable design is adopted, and the “LoRa remote transmission module” is fixed on the base table. The base table and the remote transmission module are easy to disassemble and install, and the maintenance is convenient;
Double battery backup: The remote module is equipped with 1 high-performance battery and 1 spare battery to ensure the normal working time of the water meter is ≥6 years;
High measurement accuracy: using a wet base meter, the initial flow rate is small, and the anti-drip device can be added;
The whole table is patented, and the patent name “an anti-freezing water meter with frozen state detection” can improve the anti-icing performance within -8 °C;
Through the frequency range of 470MHz~510MHz, LoRa wireless communication mode realizes real-time copying function. The transmission power is ≤50mw. The level 1 open communication distance between the concentrator and the water meter is about 1KM. By increasing the relay route, the farthest meter reading distance is about 5KM.
Battery voltage reading function: battery voltage data can be read every day through a remote meter reading platform
