ASME MFC-5.1
Measurement of Liquid Flow in Closed Conduits Using Transit-Time Ultrasonic Flowmeters
Organization: | ASME |
Publication Date: | 17 June 2011 |
Status: | active |
Page Count: | 24 |
scope:
This Standard applies to ultrasonic flowmeters that base their operation on the measurement of transit time of acoustic signals. This Standard concerns the volume flow-rate measurement of a single-phase liquid with steady flow or flow varying only slowly with time in a completely filled closed conduit.
Purpose
This Standard provides
(a) a description of the operating principles employed by the transit-time ultrasonic flowmeters
(b) a guideline to expected performance characteristics of transit-time ultrasonic flowmeters
(c) a description of calibration, verification, and diagnostic procedures
(d) a description of potential uncertainty sources and their reduction
(e) a common set of terminology, symbols, definitions, and specifications
