VEGA VEGAPULS 65 (≥ 2.0.0 - ≤ 3.8) 4 … 20 mA_HART four-wire - Manual (Page 15)

W
hen mounting VEGAPULS 65, keep a distance of at least 500 mm
(19.69 in) to the vessel wall. If the sensor is installed in the center of
dished or round vessel tops, multiple echoes can arise. These can,
however, be suppressed by an appropriate adjustment (see chapter
"
Setup").
I f you cannot keep this distance you should carry out a false echo
storage before setup. This applies mainly if buildup on the vessel wall
is expected. In this case, we recommend repeating a false echo
storage later with existing buildup.

I n vessels with conical bottom it can be advantageous to mount the
sensor in the center of the vessel, as measurement is then possible
down to the lowest point of the vessel bottom.
