Large diameter ultrasonic water meter

Product Overview

Description

 

Remote reading meter, low power consumption, small pressure loss, high precision, simultaneous measurement and display of flow rate, velocity, temperature, working time and other data information, automatic fault detection alarm, M-BUS/RS485/4-20mA/NB-IoT /LORA/GPRS and other remote transmission methods.

It can be combined with remote control valve, data collector, concentrator and management software to build "water metering intelligent management system" to realize water metering intelligent management.

 

Description

 

Ultrasonic water meter is a kind of new water meter which can detect the time difference caused by the change of velocity when ultrasonic sound beam propagates in the water upstream and downstream, analyze and deal with the water velocity and further calculate the water flow rate

 

Features

 

1. Display the cumulative flow (m3), flow rate (m3 / h), temperature (℃), water meter number, total working time, fault information, etc

2. No transmission parts, minimum pressure loss, ultrasonic measurement principle, ensure long - term measurement under various complex conditions

3. Double channel design, measuring accuracy: Class 2

4. The standard communication interface is equipped with m-bus remote transmission interface, which can choose MBUS, RS485, 4-20ma, pulse, wireless 470MHz, wireless GPRS and other interfaces to realize the function of remote meter reading

5. With battery power, flow signal, pipeline leakage, pipeline burst, water flow direction and other self-test alarm function

6. Professional pipeline design to ensure the stability of the water field under test
