Pipeline integrated ultrasonic flowmeter / LRF-2000F

LRF-2000F integrated ultrasonic flow meter integrates main unit and transducers into one unit. The transducers are installed into pipeline by screw or flange.

Features

High Accuracy measuring
Linearity: better than 0.5%, Repeatability: better than 0.2%, Accuracy: better than ±1%
Wide Measuring Range
Several types transducer for selection, measuring pipe size from DN 15mm to DN 6000mm
Easy to Operate
Browse data with magnetic stick on primary meter or reset parameter on secondary meter
Multi-display
Integrate signal detecting and flow measuring on primary meter, display accumulated/instantaneous flow, velocity in circle; secondary meter can also display over 100 menus
Far Transmission Distance
Connect primary and secondary meter through RS-485 interface, normal cable replaces special cable, transmission distance up to 1000m . Solve the problems of high cost of special cable, poor anti-interference, short transmission distance etc.

Optional transducer

Feature	Functional Type
Clamp-on transducer	LRF-2000FNB
Instatolling without stopping flow and no pressure drop Measuring accuracy up to ±1% Easy install and maintain, user can install themselves The lowest price and independent of pipe size Suitable for good conditons
Insertion transducer	LRF-2000FNC
Installing without stopping flow and no pressure drop Measuring accuracy up to ±1% Installing with special tapper after training Higher price and independent of pipe size Better receiving signal, stability and reliability for long time working
Flange connection transducer	LRF-2000FNG
Installing with cutting pipe and stopping flow, no pressure drop Measuring accurary up to ±0.5% Installing and maintaining with stopping flow, user can install by themselves Price increased with measuring pipe size The highest accuracy, better receiving signal, stability and reliability for long time working
