Longrun LRF-2000M Ultrasonic Flow Module

General Introduction

LRF-2000M is a low cost ultrasonic flow module. It is using two ultrasonic transducers that attach to the outside of a water pipe, and measures flow and temperature. The LRF-2000M calculates power and energy in real-time. It connects to the ezeio via a serial Modbus connection.



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%
