Operating Instructions, 08/2014, A5E32221386-AC
①
Distance/SV2
⑥
Level
②
High level point (default: 100%)
⑦
Low level point (default: 0%)
③
Sensor value
a)
⑧
Level offset
c)
④
High calibration point
⑨
Secondary value 1
⑤
Sensor reference point
b)
⑩
Low calibration point
a)
Referenced from Sensor Reference Point.
b)
Sensor Offset (2.3.7.3.) is a constant offset that can be added to or subtracted from sensor
reference point to compensate if the sensor has been changed.
c)
Level Offset (default O) can compensate for specific vessel configurations.
3.
Linearization can be carried out to accommodate complex vessel shapes, or to provide level
to volume conversion.
4.
The Transducer Block provides three possible outputs:
–
Primary Value (PV) / Level or Volume
–
Secondary Value 1 (SV1) / Level
–
Secondary Value 2 (SV2) / Distance (sensor units)
