Fluid Mechanics Measurements


Examples for measurement configurations and devices

A Pitot-probe (Figure 2.12) can be simply formed by e.g. bending a pipe or an injection needle. At the nose of the probe a stagnation point develops, and the total pressure is tapped through the pipe. Directional sensitivity is always a problem. Inclined incidence causes separation at the probe nose, affecting the measurement result. However, it is usually difficult to estimate the flow direction for proper alignment of the probe against the flow. An effort toward reduction of alignment errors is rounding the nose cone, in order to minimise flow separation.

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.
