Modelling and design of time-of-flight sensor

Abstract

In the presented investigation, the problem of accurate determination of low mass flow was studied. In this paper a flowmeter design applicable for measurement of low gas flow amounts is presented. To this end, the numeric model of designed flowmeter was made and the flowmeter was numerically simulated using compressible Navier - Stokes equations in two and three dimensions. The computations were carried out for several types of constructive materials of flowmeter and for several types of agitated gases. The results were compared with experimental data.
