Abstract : The patent describes a measuring apparatus which accurately measures the distance between a surface and an imaginary datum line or plane. One or more transducers are mounted on a carrier which is positionable adjacent a surface which is to be measured with respect to an imaginary datum. The surface being measured may be in the form of a complex shape, and the transducers need not physically contact the surface. Correction factors are provided for possible misalignment of the transducer carrier and also for the possible non-linear response of the transducer.
