Page 8: Instrument Description
The trajectory of the sound wave is called the acoustic path. A chord is the direct path crossing the pipe from one side to the opposite side. Using reflection, an acoustic path can consist of two or more chords. The name ALTOSONIC V12 is related to its design where 12 chords build 6 acoustic paths. -

This component increases or decreases the speed of the sound wave as it moves from one transducer to the other transducer. The transit time from Trd A to Trd B (t ) is: ϕ ⋅ In opposite direction (from Trd B to Trd A) the transit time (t ) becomes: ϕ... -

When looking at specific spots in the pipe, the local gas velocity vector may not be exactly parallel to the pipe axis. This effect can be the result of a flow velocity pattern called swirl. This is a frequently occurring velocity pattern where the gas mass in the pipe rotates as it flows. -

Page 21: Path Substitution
2.4.6. Path substitution The ALTOSONIC V12 is designed for custody transfer applications. In order to maintain the accuracy required for custody transfer measurement under all circumstances, a minimum of three out of five measuring paths must be operational. In case one or two of the five measuring paths fail during operation, an automatic path substitution procedure is started. -
