2. Level Calibration is a linear transfer function that converts a sensor value to a level
value. The level value is used for volume calculation, if that function is enabled.

3. Then linearization can be carried out to accommodate complex tank shapes, or to
provide level to volume conversion.
4. The LTB provides four possible outputs
• Primary Value (PV) / Level or Volume
• Secondary Value 1 (SV1) / Level
• Secondary Value 2 (SV2) / Distance1 (sensor units)
or
• Secondary Value 3 (SV3) / Distance 2 (any level units, except %)
1.
Level Offset (default O) can compensate for specific tank configurations.
