Abstract：Based on one-dimensional large length measuring standard device, casing coupling meter verification is non-contacted. It is more efficient, simple to operating and it also has large measuring range. Meanwhile it also overcomes the shortcomings of the traditional verification methods. The traditional verification is inefficient, complex and unable to carry out the full-length verification on the casing coupling meter because of the limited standard device length.According to the experiment, the calibration time of the traditional device for a 3m casing coupling meter is 1 h, while this device is 12 min that be 5 times faster than the traditional one. The uncertainty analysis for this device shows that the uncertainty of maximum detection point is U=0.2 mm (k=2) on 3 m casing coupling meter. The result meets the requirements of casing coupling meter regulation and this method is feasible.
