Clamp-on Ultrasonic Flowmeter

Product Manual

This clamp-on ultrasonic flowmeter is designed for long-term online measurement of various liquids. The main unit and sensors are installed separately: the main unit can be placed indoors, inside instrument cabinets or on control panels, while the sensors are mounted externally on pipelines. They are connected via dedicated cables to complete flow measurement. When matched with temperature sensors, it can also perform heat quantity measurement.

Widely applied in water supply, heating, water conservancy, metallurgy, chemical industry, machinery, energy and other fields, it serves for production monitoring, water balance commissioning, heating network regulation and energy conservation inspection. It is an essential flow measuring instrument for industrial processes.

n Installation without pipeline shutdown, no pressure loss

n Easy installation and maintenance

n Compatible with clamp-on temperature sensors to realize external pipe temperature detection and heat metering

n Suitable for pipelines of various diameters with wide application range
