WebA transit-time ultrasonic gas flowmeter for high-rangeability requirements, such as those encountered in flare-gas flow-metering, is presented. The concept of ray rescue angle for the orientation of the ultrasonic transducers in single-beam transit-time ultrasonic flowmeters is introduced to overcome the problem of ultrasonic beam drift in high-velocity flows. To … WebA vortex flow meter is a flow measurement device best suited for flow measurements where the introduction of moving parts presents problems. They are available in industrial grade, brass or all plastic construction. Sensitivity to variations in the process conditions are low and with no moving parts have relatively low wear compared to other ...
Webto compensate for these two problems. An improved version of the flare gas ultrasonic meter has been developed to demonstrate the accurate measurement of air flow up to 123.7 m/s. Testing data have been presented for two typical configurations, Bias 90 and Diagonal 45, in comparison with a Venturi reference meter.
