Influence of free gas on metrological characteristics of Coriolis flowmeters
The paper is devoted to the study of Coriolis flowmeters at the State primary special standard unit of mass flow of gas-liquid mixtures GET 195-2011 in the presence of free gas in the measured medium (MM). Depending on the free gas content in the measured medium, at different flow ranges of the measured medium, as well as at different water contents in the measured medium, flow measurement errors are determined with the use of flowmeters. An attempt is made to justify the influence of free gas content in the measured medium on the metrological characteristics of the flow measurements.
