Summary

A scanning procedure is illustrated by which a pressure sensor can be used to represent the flow field inside a duct. A computer-controlled robot positions the sensor at different locations of the cross section and orientates the three-dimensional pressure sensor in such a way that the true value of the fluid velocity can be measured. This occurs when the measured pressure reaches a maximum in one direction, whereas the difference between the values in the two other orthogonal directions is zero. Special care is taken in detecting instability regions and in checking the accuracy of the orientation, with reference to the allowable error in measuring velocity. E.F.
