How the transducer block works:
1.
The sensor technology block selects the proper echo. For an explanation of sensor
technology, see Appendix A: Technical Reference (Page 231).
The sensor value (in sensor units) is checked to see if it is within its measuring limits. If the
limit is exceeded, this results in a Bad status and the error message Failure in measurement.
The sensor value is stored in Sensor Value.
The analog signal from the sensor is transformed into a digital representation.
A Sensor Offset (default 0) compensates for changes to the sensor reference point, if
necessary.
2.
Level Calibration is a linear transfer function that converts a sensor value to a level value.
