Multihole pressure probe-Conventional multi hole probes
Product Description
Traditional multi-hole probes are proficient at measuring flow velocity and direction with high accuracy. These basic flow measurement tools can be manufactured in a variety of configurations and geometries, including straight, L-shaped, cobra-shaped, and eccentric collar runway geometries with tapered, multi-faceted, or hemispherical tips.
A complete flow data system can be obtained by pairing our multi-orifice probes with our miniature air data computers, which are available in a variety of models. When the probe is inserted into the fluid, the pressure measured at each port is interpreted by our pressure-velocity reduction software to report the magnitude and direction of the flow velocity vector relative to the probe, as well as the static and total pressure.
