In order to secure that tanks are confirmed with the requirements of legal metrology, tanks shall be built in accordance with sound engineering practice. The main target during the process of construction and building of tanks is the ability of tanks to protect the storage fluid. Geometrical shape, hydro-static preassure and temperature are the main influencers to the capability of the fluid, so this three parameter must be permanently controld. In accordance with international standards and methods in the scope of legal metrology and calibrated laboratories, ths paper will present an analysis of two methods for tank control. It will be shown excample of conformity assessment of the thank you results collected by Leica MS60 and Leica BLK360 scanner stations.

The three-dimensional (3D) model of erosion state of blast furnace (BF) hearth was obtained by using 3D laser scanning method. The thickness of refractory lining can be measured anywhere and the erosion curves were extracted both in the circumferential and height directions to analyze the erosion characteristics. The results show that the most eroded positions located below 20# tuyere with an elevation of 7700 mm and below 24#–25# tuyere with an elevation of 8100 mm, the residual thickness here is only 295 mm. In the circumferential directions, the serious eroded areas located between every two tapholes while the taphole areas were protected well by the bonding material. In the height directions, the severe erosion areas located between the elevation of 7600 mm to 8200 mm. According to the calculation, the minimum depth to ensure the deadman floats in the hearth is 2581 mm, corresponding to the elevation of 7619 mm. It can be considered that during the blast furnace production process, the deadman has been sinking to the bottom of BF hearth and the erosion areas gradually formed at the root of deadman.
