Abstract
A pig comprises a pressure vessel (7) having an inner chamber, and at least one sensing element (3) . The sensing element comprises an elongate member (s) extending radially to the centre axis of the pressure vessel and being movable with respect thereto, sensing means (6) for sensing movement of any of the elements, the sensing means comprising an electronic sensor, the said electronic sensor being mounted within the pressure housing, and wherein there is no physical connection between the said at least one sensing element and the inner chamber of the pressure vessel.
