Liquid Flow in Closed Conduits Using Transit-Time Ultrasonic Flow Meters, Measurement of
Applies only to ultrasonic flowmeters that base their operation on the measurement of transit times of acoustic signals. Further, this Standard concerns only the application of such meters when used to measure the volumetric flow rate of a liquid exhibiting homogeneous acoustic properties and flowing in a completely filled closed conduit.
