EXPERIMENTAL RESEARCHES CONCERNING THE MEASURING OF FLOW RATES IN INDUSTRIAL EQUIPMENTS

Measurements of amount and flux of different media (liquid or gaseous) are very often done in laboratories or in industry. If the amount of flowing media is small, energy, velocity and pressure caused by the flowing are small, too. Thus, for small amounts of the flowing media it cannot be used classic flow meters (rotameters, anemometers, vibratory flow meters etc.). Application of constriction flow meters requires relatively large contractions causing suitable large pressure changes and it is not always acceptable in technological processes. If a technological process requires automated measurements at a low pressure drop and the flow varies in time, it is necessary to find other measuring methods. In this paper, the author proposes a solution enabling automated measurements and causing low pressure drops.
