Fluid Pressure Measuring Device Interface

A fluid pressure measuring device interface which may be used in a submersible platform or vehicle includes an interface chamber fluidly coupled to a conduit which leads to the fluid medium whose pressure is to be measured. The interface chamber encloses a liquid-filled deformable pressure transfer container or bladder, which is generally completely surrounded by the fluid medium whose pressure is being measured. A second conduit fluidly couples the bladder to a pressure measuring device. The device can perform fluid medium pressure measurements including water pressure and wave and tide measurements. When used in an underwater structure, the conduit coupled to the interface chamber connects to the exterior surface of the underwater structure, at a point generally vertically above the interface housing.
