VEGA VEGAPULS 68 (≥ 2.0.0 - ≤ 3.8) 4 … 20 mA_HART two-wire - Manual (Page 22)

W hen using a swivelling holder, keep in mind that the distance
between antenna and socket gets smaller as the inclination of the
sensor increases. Additional false reflections may be generated which
can influence the measuring result at close range.

I f the medium has good reflective properties, VEGAPULS 68 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.
