16 VEGAPULS 43 – Profibus PA
Mounting and installation
The product echo moves to the centre of the
meas. range. At the end of the meas. range,
you now see an echo at a position where the
bottom echo previously was in the empty
vessel. This echo is a multiple echo of the
product echo and is located at twice the
distance of the product echo.
Filled vessel
In a completely filled vessel, you see addi-
tional multiple echoes at two, three or four
times the distance of the product surface
echo.
Deviating socket dimensions
Mounting on dished tank end
> 400 mm
Mounting on a block flange is especially
advantageous. Due to its very shallow re-
cess, it is an ideal solution also for hygienic
and aseptic applications.
3.2 Measurement of liquids
Flange antenna
Horn antenna on DIN socket piece
Radar sensors are usually mounted on short
DIN socket pieces. The lower side of the
instrument flange is the reference plane for
the measuring range. The socket piece
should be as short as possible.
In vessel with dished or rounded tops,
please do not mount the instrument in the
centre or close to the vessel wall.
