Details
R≥100, Temperature level: cold water should not be higher than 30℃ (hot water should not be higher than 90℃) and not lower than 0℃. Water pressure level: MAP 10Bar.
Feature
●Bluetooth water meter app can achieve self-upgrades and uploads measurement data by connecting Bluetooth DTU.
●Downlink transmission of DTU by Bluetooth communication,uplink transmission of DTU by GPRS or NBIoT.
●No need to connect 220V electric supply and wiring.
●The Bluetooth water meter adopts a prepaid mode(with arrearage and water cut-off function),no need for physical cards(no more headache with card loss and card replacement).
●Users can connect to the water meter through mobile phones.
●You can use app and bluetooth function in mobile phone to operate such as recharge,meter reading,balance query, historical usage query,recharge record query,etc.
●App also has functions such as voltage alarm,regular maintenance and management of valves.
●Bluetooth water meters can greatly save user time and reduce property management costs.
Application
Record the total amount of water flowing through the tap water pipeline.
