Legal Metrology and its Development in the Field of Calibration and Verification of Fuel Dispensers and their Application in the Mining Industry

The paper deals with metrology and special area of legal metrology, whose task is to ensure consistency and correctness of measurements. The contribution is in addition to definitions and explanations of basic concepts and principles applied in metrology, mainly presented the results of scientific research work in the interdisciplinary field of legal metrology in the Slovak republic. The main content of the paper is a description of calibration equipment for calibration and verification of fuel dispensers, description of the process of research and its application in practice. There are also shown the results of activities in the field of research and development leading to improved measurement accuracy and eliminating subjective influence the measurement. Part of the contribution is to point out the use of calibration equipment in the field of mining in some enterprises in the Slovak Republic. Accurate measurement and determination of fuel consumption in mining operations can help to plan and more accurately determine the cost of operations using with combustion engine machinery. As an example of application of the importance of using metrology equipment we chose the greatest mining and manufacturing magnesite plant in Slovakia, the company SMZ jsc in Jelsava. In this company runs mining with the help of machines driven by combustion engines.
