Abstract
A new kind of device measuring liquid level automatically is developed which is composed of camera, illuminating system and industrial computer. It’s based on image measurement technology. The image of the transparent glass liquid level gauge which is installed on the volumetric tank of a flow calibration facility is captured by a camera. After a series of image pre-processing, such as interception, gamma correction, edge detection and so on, the value of liquid level which is the liquid level of the tank can be got by so called peak method. The measurement error is 0.1mm.
