The validation of a sphere or a pig depends on the echo loss duration.
The MiniSonic-ISD or PSD calculates this duration min. / max limits from the Pig Length
(if only Spheres, then L = Pipe I.D.) and from the flow velocity. Correct data range must
be entered as follows.
∇
Choice of the data to calculate velocity
V = flow velocity (then m/s entry)
Q = flow value (then m

/ h entry)

Shorter length for Pigs (Spheres):
∇
Longer dimension of Pigs (Spheres):
V sphere / Q sphere
Min speed sphere = xx.x m/s
( Q min sphere = xxxx m3/h )
Max speed sphere = xx.x m/s
( Q max sphere = xxxx m3/h )
L max sphere = xxxx.x mm
L min sphere = xxxx.x mm
