VEGA VEGAPULS 61 (≥ 2.0.0 - ≥ 4.0.0) Foundation Fieldbus Approval according to LPR radio standard - Manual (Page 18)

If the medium has good reflective properties, VEGAPULS 61 can also
be mounted on a longer socket piece. Recommended values for
socket heights are specified in the following illustration. You must carry
out a false echo storage afterwards.

The below charts specify the max. socket piece length h depending on
the diameter d.
Socket diameter d Socket length h
80 mm 300 mm
100 mm 400 mm
150 mm 500 mm
Socket diameter d Socket length h
3" 11.8 in
4" 15.8 in
6" 19.7 in
Tip:
In new facilities it is useful to incline the vessel socket in the direction
of the outlet. False reflections from the vessel wall are thus reduced
and measurement all the way down to the bottom of the conical outlet
is possible.
