4.3 Measurement of solids
As with liquids, the instrument for solid vessels
is most of the time mounted on a short DIN-
socket piece.
Differing from the liquid measurement for
which the sensor must be in rectangular posi-
tion and hence vertical to the product surface,
the angle of repose must be considered for
solids. Optimum measurements are achieved
even when the sensor axis point is vertically to
the solid surface.
DIN-flange directed in the inclination angle on
the angle of repose of the solid
Alternatively to the inclined welded DIN-flange
you can either use on a large DIN-flange a
conical adapter with an adapter flange plate or
you use a flange pipe adapter. Please note
that due to the inclined position of the sensor a
larger flange must be selected than normally
required for the horn antenna.
