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.
