Parameters
2.3. Sensor Calibration
123
2.3.1. Sensor Units
Whatever units the sensor is measuring in.
2.3.2. Calibration Type
In "Dry" calibration, the user enters all four calibration values: High and Low Level
Points, and High and Low Calibration Points.
2.3.3. Low Calibration Pt.
Distance from Sensor Reference to Low Calibration Point (corresponding to Low
Level Point). Unit is defined in Sensor units. (In PDM, go to Device menu > Sensor
Calibration, then click on More Information, to see an illustration.)
2.3.4. High Calibration Pt.
Distance from Sensor Reference to HIgh Calibration Point (corresponding to High
Level Point). Unit is defined in Sensor units. (In PDM, go to Device menu > Sensor
Calibration, then click on More Information, to see an illustration.)
1.
Sensor Reference Point: the point to which all of the above parameters are refer-
enced, which is the flange face.
2.
Sensor Value: the value produced by the echo processing, which represents the dis-
tance from the Sensor Reference Point to the target.
3.
Level Value: the level measured in level units.
