Measures to Improve Metrological and Technical Characteristics of the Film Gas Flowmeter

The problems of low flow rate measurement (in particular, increasing the accuracy and expanding the measurement range) are relevant both in modern technologies and in experimental studies. The error of a film flowmeter depends on its design, the quality of calibration, as well as the properties of the gas under study and the film-forming liquid. The paper considers the issues of optimizing the composition of the film-forming liquid of a film flowmeter in order to improve the accuracy of measuring the gas microflow rates.
