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.
