Surface Threshold - amplitude threshold for detection of the Product level
peak. The surface threshold is designed as a number of individually
adjustable amplitude threshold points, the Amplitude Threshold Curve (ATC),
see “Amplitude Threshold Curve” on page 7-7.
Interface Threshold - amplitude threshold for detection of the Interface level
peak.
Full Tank Threshold - amplitude threshold that can be used to detect
whether the probe is fully submerged in the upper product or not.
Probe End Threshold - amplitude threshold for detection of the Probe End
peak.
Thresholds are recommended to be set to approximately 50% of the signal
peak amplitude. To adjust the Amplitude Thresholds see “Using the Echo
Curve Analyzer” on page 7-10.
