NB IOT Water Meter Brass Cold Wireless ISO 4064 Smart
NB IOT Water Meter is a new type of smart water meter. The case is made of brass. With intelligent wireless remote transmission function, in line with the international ISO4064 standard.
It can be used as a cold water meter or a hot water meter. If you are interested, please contact us.
Ⅰ.Overview
The wireless AMR water meter(NB-IOT) using of advanced wireless transmission technology, it transforms metered information of conventional mechanical water meter into electrical signal have it stored by micro-electronics control circuit. It is able to automatically read the metering data via wireless remote network and is also able to transfer the data to the back-office system (data center) after reading the meters. It can realize daily automatic data push and remote valve control valve.
Ⅱ.Features
1.Easy to build: no wiring required, easy to install and debug.
2.Low construction cost: no wiring costs, use wireless network, signal stability, fast reading data.
3.Long service life: low power design, real-time standby, battery life ≥ 6 years (Upload every 3 days)
4.Built-in valve, can remotely transmit data, remote control valve.
