Abstract
A dynamic fluid flow measurement apparatus is intended to be connected to a relative reference member, such as a marine vessel. The apparatus preferably includes a base member, a lever mechanism movable relative to the base member for transmitting force corresponding to direct dynamic fluid flow pressure applied to the lever mechanism, and a signal generator disposed in the base member for actuation by the lever mechanism. The signal generator generates an output signal corresponding to the force transmitted through the lever mechanism in response to fluid flow passed the relative reference member. In the preferred embodiment, the signal generator takes the form of a solid state pressure sensing transducer, such as a piezoresistive transducer sensor for sensing force transmitted through the lever mechanism. A central processing unit is provided in the preferred embodiment for receiving the electronic output signal from the signal generator and for generating a processed electronic output signal in accordance with a control program stored in memory. A display can be provided for receiving the output signal and for displaying a visual readout of information, such as relative speed of…
