Fluid Mechanics Measurements


Piezo-resistive principle [8]

Such types of transducers, outlined in Figure 5.7, utilise a flexible diaphragm to which a strain gauge is attached. When the diaphragm is deformed by the action of a pressure fluctuation, the strain amplitude is sensed by a resistance change in a strain gauge – termed as piezoelectric effect - that forms a branch of a Wheatstone bridge. Electric signal-processing is completely analogous to that used in hot-wire anemometry (not discussed in this note).

This lecture note aims at providing basic information on nowadays applied fluid flow measurement techniques, in terms of their operating principle, layouts, application areas, advantages, and limitations. As such, it intends to give an aid in decision-making when selecting instrumentation for the solution of various practical flow measurement problems, also providing hints for the actual realisation of the measurements.
