Ultrasonic Water Meter
Main features and characteristics:
- Using a microsecond-level high-precision chip, it has high measurement accuracy, a low starting flow rate, and can achieve drip measurement.
- Automatically saves historical data from the past 24 months, including the traffic for each month, safe and reliable.
- Data communication can achieve functions such as parameter setting, flow calibration, and centralized meter reading through infrared or M-BUS bus, and it maintains extremely low current consumption during data communication, which can greatly extend the battery life.
- In the event of faults such as power undervoltage or ultrasonic transducer failure during work, it has the functions of fault diagnosis, recording, and display. It can monitor the battery, temperature, and flow in real time, and record the date of the fault occurrence and the valid data at that time.
