This Standard applies only to ultrasonic flowmeters that base their operation on the reflection of acoustic waves, frequently referred to as a Doppler flowmeter. The flow measurement utilizes either frequency or time domain techniques. This Standard concerns the volume flowrate measurement of a liquid dominant fluid with steady flow or flow varying only slowly with time in a completely filled closed conduit.
