Automatic Identification of Float Flowmeter´s Float

According to the automatic verification of float flowmeter problems, we put forward a device, and it can acquire float height. An MVC - II - 1MM camera is used to capture flowmeter images, and saves them in computer in the form of BMP files. By some functions, such as the edge detection, filtering, binary, expansion, refined, etc, and other algorithms programmed by specific characteristics the float position is detected. This measurement has a precision of 10% smallest calibration.
