Pipeline flow measurement using real-time imaging

Flow measurements, in particular water flow pressures, are topics of great interest since the issue has an important impact on our daily life. Flow measurements can be performed by means of different devices and instruments. But, in some cases, instead of measuring in direct way the flow, it could be necessary to have pressure by means of dedicated sensors and transducers. In case of hazardous liquids, as suggested by anti-explosion liquids, any measure must be adopted to guarantee measurement and conveying in a safety conditions. So a contactless flow measurement could be a good solution thanks to the use of videomeasurements. The paper points out an experimental design and construction of a realtime system for measuring frames of water flow to be composed for determining velocity and changes. This system is suitable for pipeline grids and waterworks where it is difficult to install appropriate devices for the purposes.
