JYME1S004-LXSZ-ZL Series Wireless Direct Water Meter is a valve-free intelligent remote water meter based on Lora standard communication protocol. With LORA wireless technology, communication distance is far, convenient 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.
The water meter is designed with an electromechanical separation structure, and the measurement is accurate. The base table and the wireless electronic unit can be completely separated, and their own independent operation is convenient to install, which is convenient for later maintenance.
