Ultrasonic gas flowmeter
-- Control Engineering, 3/1/2002
Waltham, MA - According to its developer, the DigitalFlow GC868 flowmeter is the world's first clamp-on ultrasonic flowmeter for gases at high or low pressure in pipes. The flowmeter was tested exten-sively on metal pipes containing air, hydrogen, and natural gas over a range of pipe sizes from 3- to 36-in. diameter. Demonstrated accuracy exceeds ±2% of reading, with a time averages accuracy of ±1% of reading. Repeatability is ±0.5% of reading. The device is especially useful for metering erosive, corrosive, toxic, high-purity, or sterile gases. It has no wetted or moving parts, requires no regular maintenance, causes no pressure drop, and has wide rangeability.
