JYME1S004-LXSZ-VB Series Wireless Direct Water Water Meter is a magnetic direct-sensitive smart water meter based on NB-IoT standard communication protocol. Adopt NB-IOT wireless technology communication, the communication distance is far without the need for networking. Easy to write reading and controlling water meters, realizing remote direct reading of water meters, effectively avoiding the management department on top table reading, and improving meter reading efficiency.
In order to more real-time operating valves, we use more advanced communication technology than infrared, NFC, etc.: low-power Bluetooth 5.0, ie BLE. It can be recharged, self-opening valves, etc. The water meter is designed with an electromechanical separation structure, and the measurement is accurate. The base table and the wireless acquisition module can be completely separated, and their own independent operation is convenient to install, which is convenient for later maintenance.
