Image Processing and Signal Recovery from Instrumentation and Control Device for Test Facility of Cryogenic System

Computerized sensors and automation helps industry to get better accuracy and throughput. Aim of this proposed system is digitization of fluid flow rate measuring device called Rotameter. In market for different fluids different rotameters are available and this system is able to support them independent of its fluid. It uses BeagleBoneBlack a mini computer for all its computation needs and a camera device as an eye of the computerized sensor to read the rotameter. Application code is entirely written in C++ with Qt for GUI and OpenCV for camera handling. This system gives real-time measurement and it is more accurate than human measuring. It requires one time calibration to detect rotameter. This system is highly modular and scalable. Currently system is designed to consider one rotameter at a time but with little modification system can be easily extended to centralized system with multiple rotameters and cameras.
