The M-Bus/ RS485/ Pulse Output/ Lorawan Ultrasonic Water Meter is a new type of electronic water meter for flow measurement based on the principle of ultrasonic time difference. It is used to measure the instantaneous flow and cumulative total amount of water flowing through the tap water pipe ultrasonic water meter has remote function, and the remote reading of data can be realized through the system platform.
