Some pitot–static systems incorporate single probes that contain multiple pressure-transmitting ports that allow for the sensing of air pressure, angle of attack, and angle of sideslip data. Depending on the design, such air data probes may be referred to as 5-hole or 7-hole air data probes.
In these kinds of measurements, the most practical instrument to use is the pitot tube. The pitot tube can be inserted through a small hole in the duct with the pitot connected to a U-tube water gauge or some other differential pressure gauge for determining the flow velocity inside the ducted wind tunnel. One use of this technique is to ...
A Cobra probe is a device to measure the pressure and velocity components of a moving fluid.It is a multi-holed pressure probe with rotational axis of the probe shaft coplanar with the measurement plane of the instrument.
A tri-axial particle velocity probe may be used to enhance speech reception in a video conferencing scenario: Y. Wu, K. T. Wong, S.-K. Lau, X. Yuan & S. K.

Step 3: The probe is scanned over the blade root. In this case, an indication (peak in the data) through the red line (or gate) indicates a good blade; an indication to the left of that range indicates a crack. Principle of ultrasonic testing. LEFT: A probe sends a sound wave into a test material.
A sound velocity probe is a device that is used for measuring the speed of sound, specifically in the water column, for oceanographic and hydrographic research purposes.
At the time of re-targeting, whether or not a related science mission would be carried out in 2020 was yet to be determined, based on NASA's budget and the health of the probe. [73] A 71-second engine burn on October 4, 2012, changed the probe's velocity by 2 m/s (6.6 ft/s) to keep the mission on track. [74]
