Fluid Mechanics Measurements


Principle and layout

Figure 7.6 and Figure 7.7 present sketches of the MHD meters. The measurement method relies on the Faraday induction principle. If a magnetic field of inductance B is generated, and a magnetically conductive medium, having a characteristic length L, is translated normal to the magnetic field lines, a Faraday voltage u is induced between the ends of the medium, separated at a distance L. This voltage is proportional to the translation velocity v of the medium, according to the Faraday induction law, demonstrated in Eq. (7.8):

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.
