The application of ultrasonic flowmeter on trade measurement in Yulin gas field

摘要

In this paper, the working principle and system components of ultrasonic flowmeter are briefly introduced In accordance with ultrasonic flowmeter applicated in YuLin gas field, comparing the transmission error of upper and lower streams measurement on this basis, the pre-Operation measurement error and actual flow test/ calibration are explored and analyzed, and for the better use of ultrasonic flowmeter, authors put forward their understanding and recommendations.
