Ultrasonic Flow Module_Longrun_Ultrasonic Flow Meter-CHINA LONGRUN

Name：Ultrasonic Flow Module/RTU

Model：LRF-2000M

General Introduction:
LRF-2000M, the ultrasonic flow module, is best choice for system integration or network measurement because of its small volume, light weight, easy operation, power function and lowest cost.

Features:

Powerful Functions

Current output: 4-20mA, one channel, can be used for flow/heat transmitter;

OCT output: two channel, can be used for flow / heat switch;

Current input: 4-20mA, three channel, can be used for data collector;

Tri-wire resistance signal input (PT100): two channel, can be used for calorimeter.

Far transmission distance

Connect flow/heat module and secondary meter through RS-485 interface, transmission distance up to 1000m .

Solve the problems of high cost of special cable, poor anti-interference, short transmission distance etc.

Wide measuring range

Several types transducer for selection, pipe size from DN 32mm to DN 6000mm

High Accuracy measuring

Accuracy: ±1%, linearity: 0.5%, repeatability: 0.2%
