Abstract
Methods and systems for measuring the pressure of a fluid. A flexible barrier separates the fluid from the pressure receiving surface of a pressure sensing device. The pressure of the fluid is transferred through the flexible barrier to the pressure receiving surface. The flexible barrier may be in abutting juxtaposition with or may be spaced apart from the pressure sensing surface. In either case, the flexible barrier is coupled or held in defined relationship to the pressure sensing surface such that the pressure receiving surface will receive the substantially actual pressure of the fluid even when the pressure of the fluid is less than the ambient atmospheric pressure. Coupling of the flexible barrier to the pressure receiving surface may be achieved by any suitable means, including adhesive or the application of a full or partial vacuum between the flexible barrier and the pressure receiving surface.
