These probes were designed and patented for applications requiring a very high range of incidence angles. As their name suggests, they are capable of near-omni-directional flow measurement. Omniprobes are also ideal in applications where the predominant direction of the flow is not known in advance or where the probe may see a complete reversal of the flow during testing. A micro-machined spherical tip accommodates 12 pressure ports that allow for measurement of +/- 150 degrees of flow angle.
