Pipeline Operators have used Ultrasonic meters commercially for gas custody transfer applications since the late
‘90’s. These meters’ combination of operating features, including superior rangeability and on-board diagnostics
have made this the technology of choice for most high volume gas metering applications. As user comfort with, and
capabilities of, the technology has increased and the size and cost of ultrasonic meters has decreased, Operators
and Manufacturers continue to stretch the envelope of application possibilities. This includes use in upstream,
corrosive and high CO2 applications, where the technology previously couldn’t work or didn’t make economic sense.
