Fundamentals of Process Measurement

Synopsis
A video-based self-training course on the methods and technologies used for measuring pressure, temperature, flow and level, focusing on the various measurement methods commonly used in the process industries. Looks at the variables measured, the evolution of measurement methods, and the features and limitations of each of the methods presented.
1: Defines pressure; references used for absolute, gauge, and differential pressure; evolution of measurement methods; pressure sensors using elastic elements; strain gauges, piezoelectric transducers, variable capacitance and other types of pressure transducers; operation of the basic pressure controller; importance of pressure measurements for inferential measurement of flow, level, temperature and other process variables.
2: Defines temperature, emphasising the difference between temperature and heat; early measurement devices, showing how reference scales were developed; early control devices; RTDs, thermocouples, thermistors and other electronic methods; emerging technologies such as acoustic, magnetic and quartz-based thermometry.
3: Level measurement defined to include density and interface; early measurement methods, including rod gauging and floats; needs for methods that can be incorporated into control systems; pressure-based methods such as head, bubbler and differential pressure measurement; float-type devices and displacement methods; emerging technologies including capacitance, RF, conductivity, quartz and radiation.
4: Flow defined, distinguishing between mass and volumetric flow; differential methods including orifice plates, venture tubes, flow nozzles and Pitot tubes; positive displacement methods, vortex shedding, electromagnetic, ultrasonic and Coriolus effect meters; selection criteria.
