Abstract: Clamp-on metering of flowing liquids has been known since the 1960s, and measurements of natural gas flow using wetted transducers in contact with the gas has been known since the 1970s. The past decade has seen ultrasonic flowmetering technology gaining widespread acceptance in the petrochemical and chemical industry. Until now, a portable flowmeter using clamp-on techniques to measure the flow of industrial gases in steel pipes at low (under 8 bar or 120 psig) to medium pressure has remained elusive. This paper discusses clamp-on ultrasonic gas flow measurement equipment to measure low-pressure (above 4 bar or 60 psig) gas flow in metal pipes. Some laboratory (air and gas mixture) and field (methane) calibration data, and industrial applications for gases, saturated and superheated steam and instrument air will be presented. These are mostly in the P range of 4 bar and higher, for steel pipe diameters in the range 3-inch to 30-inch (75 to 750 mm), and bi-directional flow velocities up to 135 ft/s (40 m/s).
