Measurement Of Solids - Vega VEGASON 51K Operating Instruction

Mounting and installation
Pump shaft
Narrow shafts and shaft openings (vessel
openings) with very rough walls and shoul-
ders aggravate an ultrasonic measurement
due to strong false echoes.
Shaft and vessel openings
Narrow, very rough shaft, well and vessel
openings can be overcome by a socket
piece as described under "4.4 Socket exten-
sions" (left lower half of the figure).

You can realise very good meas. results with
a meas. pipe in continous narrow shafts, see
figure. The meas. pipe used must have
smooth walls inside (e.g. PE-sewage pipe)
and a diameter of ³100 mm. This coordination
works without problems as long as the inside
of the meas. pipe has no build-up (cleaning).
Also check the use of hydrostatic pressure
transmitters or capacitive electrodes.

4.3 Measurement of solids

Flange mounting
As with liquids, the instrument can also be
mounted on a short DIN-socket piece in solid
vessels. The socket axis must point to the
vessel outlet or should be directed vertically
to the product surface and must be very
short (< 100 mm).
