AXIAL HEAT TRANSFER EFFECTS ON THE PERFORMANCE OF A THERMAL DISPERSION MASS FLOW METER

Klemen Rupnik, Jože Kutin, Ivan Bajsić

Abstract

The axial heat transfer effects on the performance of the thermal dispersion mass flow meter are studied by employing an analytical one-dimensional model and a numerical two-dimensional model of the thermal flow sensor. The relationship between the measurement characteristic and the temperature difference between the sensing element and the base is analysed and possible methods to practically implement the correction of the measurement characteristic are proposed.
