For two chords:
∇
Choice of probe:
Same choice for the 2 chords
∇
If SE (External probes)
/
= single traverse
V
= reflex mode
N , W
= 3 or 4 paths
If SM (wetted internal probes)
See parameters L , D , Cv
∇
Management of amplification gains:
ESC Mode recommended.
(ESC = Echo Shape Control)
Otherwise :
If
MANUAL
:
(Gain adjustment.)
If
AUTO
: Margin
(Over-amplification compared to
critical gain Go. )
∇
If SM choice: position of probes depending
on geometrical measurements .
as distance between probes , face
to face , per chord ( L )
∇
as projected distance onto flow axis
(Part of L concerned with the flow)

Calculation weighting
(As per probes position)
