Sažetak
This paper presents an investigation of liquid storage tanks capacity. A measurement method used in maintenance is shown for liquid tanks manufactured by DIN6602 standard. Measurements were conducted with calibrated measurement etalon AM ET 1500 Litres. Relevant data was analysed with software TankCalc and the results of dry and combined (wet) measurement method were compared. The process and regulations for necessary calculations are shown and the results are shown graphically for better understanding. A method for calculation under the influence of inclination is shown and recommendations for error reduction are given. The emphasis is given to differentiate the advantages of geometrical towards the advantages of combined measurement method. Specifically, these two methods are most wanted by the owner of the liquid tanks and this investigation was to explore what can be expected from each method with respect to errors. Also the paper points out the importance of proper design of liquid storage tanks and an investigation of storage tank for petrol E 95 with volume 50 m3 is shown. The importance of maintenance and measurements can be explained with the example of the propane tanks. The propane tanks are an interesting technical challenge, as the propane boils at normal room temperature. The optimum way of storing propane is in liquid form, and that propane is kept in a liquid state at room temperature, it must be kept under pressure. In order to avoid the explosion liquid tanks must not be filled beyond 80 % of full capacity (volume), as the incompressible liquid propane changes at the temperature change.
