Understand Interface Detection

Interface Detection relies on there being a product property that can be measured by a hardware detector as the batch passes by in the pipeline. Density and sonic velocity are the properties that can be used for this. Batch densities and sonic velocities are detected using densitometers or sonic velocity detectors, respectively. By comparing the detectable property of the current batch and the upcoming batch, a threshold is determined at which the property value change will signal arrival of the upcoming batch. This point is referred to as the batch interface or batch cut. The detector value is monitored and compared to the threshold. When it reaches the threshold, the arrival of the batch interface is declared.

Threshold is determined using the cut type and a configured property value limit at the detector. For more information, refer to Access the Cut Type Summary window.
