This article is aimed at comparing the effectiveness of testing the dimensional parameters of a tank wagon with an internal ribbing with a nominal volume of 85 m3 in a production plant. One of the used methods is the traditional volumetric method, ie measuring the volume of water with a pair of flowmeters when filling the vessel. The second method is a method of computer processing of data obtained by 3d scanning of the interior of the tank from several positions and the subsequent composition of the tank model and calculation of its volume using the PolyWorks program. Evaluation of both measurement methods revealed that despite the non-trivial internal division of the measured object, both methods are sufficiently accurate, and even in this case the scanning method provides the measurement result several times faster compared to the volumetric method. In the reported example, measurement time spent to achieve results for the scanning method was approximately one third comparing with that of the water filling.
