Abstract : The patent is for a null adjustable vortex rate sensor which enables the precise control and relocation of the stagnation point of the fluid stream with respect to the null line of the pickoff located within a said chamber. The null adjustable vortex rate sensor is a vortex rate sensor with a fixed position pickoff and a fixed position drain, a rod being concentrically located in the drain and extended from the drain into the chamber. The horizontal adjustability of this rod inside the drain controls the location of the stagnation point at the pickoff within the chamber very precisely. The pickoff provides a differential pressure signal which is a function of the angular rate of rotation of the chamber in inertial space.
