Product Description
Lorawan Nb-IoT Wireless AMR Interfaces Ultrasonic Water Meter
The ultrasonic water meter(7520) precisely measures water flow by calculating the time difference of ultrasound propagation in the flow, offering high accuracy, bidirectional measurement, and the advantage of no moving mechanical parts.
Features
- Display with error and alarm codes including leakage detection
- Ultrasonic water meter detection data is more accurate
- Bi-directional flow measurements, Improved measurement accuracy, and applicability.
- Ultrasonic water meter is designed with no moving parts to reduce wear and tear
- The water consumption value can still be accurately obtained at a low flow rate of 3L/h
- Record total volume as small as 1mL
