Ultrasonic Water Meter UWM

SKU: UWM

Doc No: UWM-DS-EN-10

Introduction

UWM Ultrasonic water meter is a new type of water meter that detects the time difference caused by the change of velocity when the ultrasonic beam propagates in the opposite direction of the water, and analyzes and processes the flow rate of water to further calculate the flow of water..

Features

No mechanical movable parts, impurities in water can’t be affected, long service life.

Wide measurement range. Very small flow can be measured.

Various alarm functions: Battery voltage can alarm, empty tubes, or pipes that are not full of water, transducer fault alarm, and more.

Low-power design and the use of high-energy batteries can work for 8 years and more.

The communication interface is LoRaWAN or RS485 ModbusRTU.
