LRF2000P Ultrasonic Flow Meter

LONGRUN LRF-2000P portable ultrasonic flow meter can be powered by a rechargeable battery or 220VAC.It has a built-in printer and a data logger. Installation is non-intrusive.

LR F -2000P Portable ultrasonic flow meter realizes the non-contact measurement. It is ideal for flow surveys and closed-pipe applications where non-invasive measurement of liquids is required.

Temperature and heat can also be measured by connecting a clamp-on temperature transducer. Widely be used in water supply, heat supply, chemical industry, machinery, and energy resources


  • Accuracy Linearity: better than 0.5%, Repeatability: better than 0.2%,Accuracy: better than ±1%
  • The non-intrusive clamp-on transducer, no pressure drop, no pipe disturbance.
  • Wide measuring range Several types transducer for selection, measuring pipe size from DN 32mm to DN 6000mm
  • Large capacity battery Built-in rechargeable Ni-MH rechargeable battery provides over 20 hours of continuous operation
  • Built-in printer Available to print data in real-time, also available to timed print over 20 pre-set measuring results
  • Built-in data logger Uplink over 20 measuring data to computer or internet
  • Data storage Store over 20 pre-set measuring results to SD card, make it easy to data analysis and statistics
  • Rs485 communication interface Upload the parameters and measuring results to compute
