3. Fluid flow in a pipe
3.1 Measurement execution
3.1.1 Choice of measuring section
As in the case of free-surface flow, the measurement cross-section must be such that the velocity profile is regular, without excessive turbulence or rotation. As far as possible, the chosen location should therefore satisfy the following conditions:
be located in the longest straight section available, far downstream of any singularities (elbow, valve, etc.); it is generally accepted that the straight lengths...
