Flexim's Fluxus F601 portable clamp-on flowmeter with a NEMA 4X housing enables non-invasive flow measurement with ultrasound. Clamp-on transducers are fixed on the pipe; no process interruption is needed for commissioning. Only two transducer pairs are needed to cover the diameters most common in industrial applications (1/2 in. to 96 in. OD), the full transducer range covers ¼ in. tubing to 20-ft penstocks. The Lithium ion battery is good for 14+ hours of measurement.
