General Introduction:

The highly integrated LRF-2000W ultrasonic water meter is designed and manufactured strictly according to GB/T778.1-2007, ISO4064-1:2005 etc., based on  ultrasound transit-time measurement technology.

ultrasonic water meter has wired type as standard configuration, wireless type need to be customized.

 

 

●  compact, all plastic,IP68 protection grade

●100:1 range ratio with high accuracy

●pipeline integrated probe, not easy to produce scaling

●ultrasonic signal is adaptive to measure water containing impurities

●single chip SOC digital time-difference processing

●multi-line display with status,  touch buttons operation

●optional built-in Lora or NB-iot function

●RS485 and MBUS dual interfaces 

●multi-communication protocols like MODBUS,MBUS,and CJ188 

●external power supply can be connected

●built-in battery of 10 years service life 

●reliable and low price ,suitable for mass applications

Choose the installation point：

Correct installation point		Wrong installation point
Lowest point of the pipe line, water will be full of pipe. Flow is vertically or obliquely upward. Upstream straight pipe line≥5D.		Highest point of the pipe line, water would be not full of pipe. Flow is vertically or obliquely downward. Upstream straight pipe line≤3D.
