Note!
The distance unit is defined during the first setup of the instrument. If required, it can be changed
in the "device properties/operating params" menu.
2.1.6 "LVL N linearisation" (N = 1 or 2)
The "linearization" is used to convert the level into other quantities. Especially, it can calculate the
volume or mass within a vessel of arbitrary shape. The Prosonic S provides different linearization
modes for the most common types of vessels. Additionally, a linearization table for arbitrarily shaped
vessels can be entered.
"type"
Use this parameter to select the type of linearisation.
Selection:
• none
In this linearization type the measured level is not converted but displayed in the selected level
unit (see above, "unit level").
• linear
In this linearization type the displayed value is proportional to the measured level.
The following additional parameter have to be specified:
– the unit for the linearized value, e.g. kg, m
3
, ft
3
, ... ( "customer unit" )
– the maximum capacity (a) of the vessel, measured in the customer unit ( "maximum scale" ).

Note!
Number and type of the parameters in this set depend on the
selected linearization type.
Only the parameters "type" and "mode" are always present.
