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
