METHOD AND ULTRASONIC METER SYSTEM FOR DETERMINING PIPE ROUGHNESS

摘要

A method and ultrasonic meter system for determining pipe roughness. At least some of the illustrative embodiments are ultrasonic meters comprising a spool piece, and a first transducer pair mechanically mounted to the spool piece. The ultrasonic meter is configured to determine diagnostic data based on acoustic signals transmitted between the first transducer pair. The ultrasonic meter is configured to determine changes in the roughness of a pipe mechanically coupled to the ultrasonic meter based on a trend of the diagnostic data (wherein the trend comprises a substantially constant value of about unity for both asymmetry and cross flow and a substantially changing value for profile factor).
