Standard Test Method for Open-Channel Flow Measurement by Acoustic Velocity Meter Systems
|Publication Date:||15 April 1993|
|ICS Code (Flow in open channels):||17.120.20|
This test method covers the measurement of flow rate of water in open channels, streams, and closed conduits with a free water surface.
The test method covers the use of acoustic transmissions to measure the average water velocity along a line between one or more opposing sets of transducers - by the time difference or frequency difference techniques.
The values stated in SI units are to be regarded as the standard.
