เครื่องวัดอัตราการไหลของของเหลว Ultrasonic Flow Module / LRF-2000M

Product Description

  • 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 15mm to DN 6000mm

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