LRF2000P Ultrasonic Flow Meter With Inner Printer

Ultrasonic Flow Meter

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.

LRF-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. 

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