Name：Ultrasonic Heat Module
Model：LRF-2000M-R
General Introduction:
LRF-2000M-R, the ultrasonic heat 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 DN32mm to DN6000mm
High Accuracy measuring
