Experimental Device for the Measurement of Small Gas Flows Utiliying the Principle of Lamilar Flow Elements

Abstract

In this paper, the authors proposed an experimental device for measuring small flow rates of gaseous media. The device is based on the measurement of the pressure gradient upstream and downstream of the measuring element. The materials used in the design and construction of the device provide local pressure resistance, which enables accurate measurement. The proposed device can serve as an alternative to actual measuring devices for detecting the instantaneous quantity flowing in the measurement assembly. The results of the experimental measurements will be used to determine the characteristics of the measuring elements of the device.
