Fluid Mechanics Measurements


Propeller meters

Such meters (e.g. Figure 3.1) incorporate a small "turbine rotor" and are based on the principle that the rotational speed of the meter is approximately proportional to the local flow velocity. The rotational speed is sensed by a counter, and the number of counts per time unit is displayed. The rotations can be detected mechanically, optically, or by inductive means (see the turbine flowmeters in Chapter 7 for further details.) Such devices require periodic calibration, given that e.g. the mechanical parameters of the bearing of the rotor may change in time.

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.
