Abstract
A method of non-invasively determining an internal pressure inside an object, such as a pipe or a tube, includes determining, with a hoop strain sensor on an outer surface of the object, hoop strain of the outer surface of the object; determining, with an axial strain sensor on the outer surface of the object, axial strain of the outer surface of the object; determining, with a manometer, an external pressure external to the object; and determining the internal pressure inside the object based on the hoop strain, the axial strain, the external pressure, an outer dimension of the object, a wall thickness of the object, a modulus of elasticity of the object, and a Poisson ratio of the object.
