Abstract: Level measurement was a vital parameter in process industries and it demands the need for cheap and non-contact measurement which was addressed in this paper. A fully automated computer based system of non-contact level measurement using image processing technique was proposed. The design consists of float allowed move freely in the vertical column when the liquid level changes. The image of the float is acquired and processed to extract its dimension and the extracted dimension is calibrated in terms of actual level. Various dimensions such as image pixel count, float area, side of a square float and radius of a circular float was considers for level measurement and their characteristics are analyzed. Finally, a GUI was developed to monitor and calibrated the instrument remotely.
