ABSTRACT:
A pressure operated speed indicating system for a vehicle operating in a fluid, such as a speed boat, has a mounting bracket which enables a pressure sensing or pitot tube having a pressure sensing opening to be placed in an optimum position with respect to the boat. The mounting bracket grips the strongest portion of the tube to minimize tube deformation or breakage in use. The mounting bracket also assures that the pressure sensing opening of the pitot tube will remain in a forward facing position substantially transverse to the longitudinal axis of the boat. An improved connection fitting for connecting the pitot tube to a resilient conduit placing the tube in fluid pressure transmitting communication with a pressure operated speedometer is also provided. This fitting facilitates installation or replacement of a pitot tube in the system. The fitting contains a fluid flow damping orifice which dampens fluctuations in the fluid pressure imposed on the sensing opening and transmitted through the fitting to the pressure operated speed indicating gauge.
