E: Profile structure
2) Level Calibration is a linear transfer function that converts a sensor value to a level
value.
1)2)
3) The Transducer Block provides three possible outputs
• Primary Value (PV): Level (level units)
3)
• Secondary Value 1 (SV1): Level (level units)
• Secondary Value 2 (SV2): Distance (sensor units)
1)
Sensor Offset (2.3.5.3.) is a constant offset (negative or positive) that can be added to
sensor value to compensate if the sensor has been changed.
2)
Level Offset (default O) can compensate for specific vessel configurations.
3)
LR560 PA does not support Volume.
