Multipath Ultrasonic Meters For Natural Gas Custody Transfer

摘要

Ultrasonic meters are the overwhelming technology of choice for large-capacity gas measurement stations because of their reliability and rangeability. Speed of sound diagnostics inherent in these transit time meters, coupled with industry-established speed of sound calculations based on gas properties, yield the additional advantage of providing a simple technique to validate meter integrity in the field.rnManufacturers evaluate design options and adopt technologies best-suited to their intellectual property and cost-benefit analysis. The goal is to provide customers a reliable and economical solution to their flow measurement challenges, but because of necessary tradeoffs, performance of individual meters varies and users should evaluate them on the basis of the technology that best suits their individual firm's operational needs.
