Parameter reference
Linearization Table must be selected in order for level/volume values [see XY
a)
index (2.4.1.5.)] to be transferred.
Maximum Volume (2.4.1.2.)
The maximum volume of the vessel. Units are defined in PV Units (volume/ level) (2.3.3.). Enter
the vessel volume corresponding to High Calibration Point. The volume calculation is based on
the maximum volume and scaled according to the vessel shape selected. If no vessel shape is
entered, the default is 100, and the reading will be a percentage value.
Values
Related Parameters
For readings in volumetric units instead of percentage values:
1. Select a volumetric unit from PV Units (volume/level) (2.3.3.).
2. Enter the vessel volume corresponding to High Calibration Point.
