In this article, the authors describe a method for measuring local direction and total and static pressures of a flow by means of a fixed probe, provided that the local air flow does not make an angle of more than 80 degrees with the axis of the probe.Abstract:
This paper describes a method for measuring local direction and total and static pressures of a flow by means of a fixed probe, provided that the local air flow does not make an angle of more than 80 degrees with the axis of the probe. The probe is easily manufactured from standard-sized tubing materials. The power series calibration method used with the probe results in explicit polynomial expressions for the desired aerodynamic properties. The calibration method is easily programmed on a data acquisition system. This paper includes an example of a complete incompressible calibration.read more

Modelling, calibration, and error analysis of seven-hole pressure probes
TL;DR: In this paper, the calibration of a non-nulling, conical, seven-hole pressure probe over a large range of flow onset angles is described, and the calibration procedure is based on the use of differential pressures to determine the three components of velocity.

Seven-hole cone probes for high angle flow measurement Theory and calibration
TL;DR: In this article, a non-nulling seven-hole conical pressure probe capable of measuring flow conditions at angles up to 75 degrees relative to its axis is described, which can be used in subsonic compressible and incompressible flows.

Seven-Hole Pressure Probe Calibration Method Utilizing Look-Up Error Tables
TL;DR: In this paper, a two-step calibration and measurement procedure for seven-hole pressure probes has been developed that allows simple and accurate real-time processing, which adds an extra step to traditional least-squares calibration schemes such as Gallington's method.

Flight Measurements of a Wing Tip Vortex
TL;DR: In this article, the wing tip vortex generated by a DeHavilland Beaver was made with instruments mounted on a sailplane, which was towed behind the aircraft, and data at three different downstream locations were obtained by using three different tow rope lengths.
