21st International Research/Expert Conference
A continual development of science, engineering and technology resulted in usage of reliable, durable instruments and devices which maintenance costs are reduced to minimum during their life-time. Nowadays, usage of flow-meter based on the Coriolis force on measuring places is increasing. An everyday flow measurement is known problem of calculation between mass and volumetric flow and it is stressed in fiscal measurement especially in the oil industry. To get accurate mass units from volumetric, beside volumetric meter, it is necessary to include additional measurement apparatus for measurement of temperature, pressure, density and other variables. All mentioned parameters in continual flow process makes calculation harder and in many cases makes uncertainty higher. In this paper, important parameters for proper design and selection of a certain flow meters will be presented. Also, basics of measurement uncertainty will be presented under conditions of relatively low measurement passes as well as basic information about appearing of Coriolis force and Coriolis mass flow meter.
