Abstract
An omnidirectional pressure sensing head includes a rotatable hub; a channel extending through the hub having an inlet and an outlet; and a single pressure sensing port in the hub disposed in the channel between the inlet and outlet for sensing the dynamic pressure of the fluid through the channel which is a function of the speed of the hub through the fluid and the rotational speed of the hub.
