Product Description

JYME1S004-LXXZ-FL Series Wireless Direct Desk is a non-magnetic direct-reading smart water meter based on Lorawan standard communication protocol and infrared communication. With LORA and IR 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 electromechanical separation structures, and is not subject to magnetic field, 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.
