This article continues the theme of describing the technical and economic advantages of applying internal diagnostics for sensors, over traditional centralized schemes. In a previous article, this author argued for the need to create a standard set of metrics that describes the validity of measurement data. At the end of that article, the SEVA (self-validating) sensor was outlined. The SEVA sensor is described here in more detail, and uses as an example, a prototype based on a commercial mass flowmeter developed by Oxford University, The Foxboro Co. (Foxboro, Mass.), and Imperial Chemical Industries (London). (from Author).
