VEGA VEGASON 71 - 1 … 75 - 1 - Manual (Page 42)

Adaption to the product
42 71 - 1 … 75 - 1
Product type MODE 1 - 09
The product type together with the vessel geometry
can generate different reflections and therefore
multiple echoes.
The available product type can be selected in this
mode. With this selection the data of the factory
preset of mode 1 - 10 and 1 - 11 can be activated.
The echo amplification is reduced or adapted after
the measuring window.
Programming example:
Change of liquids to solids .......................................
• select mode 1 - 09 in MODEFIELD
• program figure 0 in PARAMETER FIELD
• then store with STO-button
Product type ................................ Mode 1 - 09 = 1 = liquids Mode 1 - 09 = 0 = solids
Liquid solid
vessel geometry solid features
- flat vessel top - particle size > 10 mm
- dished vessel top - angle of repose 0
°
Liquid MODE 1 - 10
The vessel geometries of tank ceilings generate
characteristic multiple echoes. They can be suppressed by adaption. A flat ceiling
is programmed as factory preset.
Features:
Mode 10 = 1
flat vessel tank ............................. = weak tendency to multiple echoes
= 0 dished vessel top ......................... = strong tendency to multiple echoes
(parabolic effects in the top area of tank)
Programming example:
Change of flat to dished vessel top ...........................
• select mode 1 - 10 in MODEFIELD
• program figure 0 in PARAMETER FIELD
• then store with STO-button
