Integrated 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
High Protection Grade
Protection grade of primary meter is IP68, can work in 2m of water
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.
