Ultrasonic multipath flowmeters for liquid hydrocarbon custody transfer They reliably meet or exceed demanding accuracy standards

摘要

Due to significant accuracy improvements during the past decade, multipath ultrasonic flowmeters are the fastest growing flowmeter technology, gaining wider usage in the petroleum industry for liquid hydrocarbon custody transfer measurement (Fig, 1). With the introduction of enhanced signal processing and multiple channel design, multipath ultrasonic flowmeters consistently and reliably meet or exceed the demanding accuracy standards required for oil custody transfer metering and fiscal accounting (less than 0.2% of measured value).
