Product Description

Bulk ultrasonic water meter

An ultrasonic LoRaWAN water meter is a smart water meter that combines ultrasonic flow measurement technology with LoRaWAN wireless communication technology. This combination offers high-precision measurement and remote data transmission capabilities.

Product Features

The ultrasonic LoRaWAN water meter parameters can be read and modified via the optical interface.
The water meter's firmware can be upgraded and updated through the optical interface, facilitating optimization of the product's function.
The device's static current is less than 25 μA, and the overall operating lifespan exceeds 6 years (based on a reporting frequency of 6 times per day).
A capacitive button can trigger device reporting, which is convenient for on-site network testing (the button trigger includes an encoding function to prevent accidental activation during transportation; see "Button Operation Encoding" for details).
The water meter is designed with status indicators and data transmission indicators for easy device status monitoring.
Built-in high-precision clock.
The ultrasonic LoRaWAN water meter includes an internal watchdog management system to prevent abnormal device operation.

Working Principle

Ultrasonic water meters are a new type of water meter that can detect the time difference caused by the change in speed when the ultrasonic beam propagates through the water upstream and downstream, analyze and process the water's flow rate, and then calculate the water's flow rate further.
