In the presented investigation, the problem of accurate determination of low mass flow in biochemical laboratories 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. This model simulates both the steady-state and the dynamic operation of the flow sensor. The results were compared with experimental data. The designed flowmeter was used in a biochemical laboratory.
