An apparatus is provided for use in monitoring for destructive wet compression power augmentation-related casing distortions in an industrial gas turbine equipped with and employing wet compression power augmentation, in the form of a) an outer ring member having an inner diameter which exceeds the outer diameter of a gas turbine section downstream of the compressor, b) three or more structural members spaced substantially equally over the outer ring member's inner circumference and which extend radially inwardly in a common plane to define a central opening about the gas turbine, with the common plane defined by the three or more members being parallel to a plane including the outer ring member over its circumference and the outer ring member's center of mass and with one of the three inwardly-extending members being equipped at its inner end with a socket or ball element of a ball and socket joint, and c) a laser reflector positioned on the outer ring member.
