Optical height of fill detection system and associated methods

摘要: The height-of-fill of a container comprising body having an optically detectable feature, and contents filling the up to fill level, at least measuring portion extending from feature level being capable transmitting electromagnetic radiation, is determined by illuminating with radiation; forming image part this container; analyzing data processing means identify: (a) first region intensity that varies in accordance properties feature; (b) second optical below determining distance between point within upper edge region, thereby height-of-fill.
