Development of Mathematical Model of Two-channel Microwave Measuring Converter of the Humidity of Natural Gas

Abstract: Обґрунтовано вибір хвилеводного надвисокочастотного методу вимірювання вологості природного газу, в якому на відміну від відомих, запропоновано використання біжучої хвилі у хвилеводі, при цьому оцінюються зміни діелектричних властивостей газів у разі їхньої взаємодії з хвилями НВЧ діапазону. Запропоновано математичну модель НВЧ вимірювального перетворення вологості природного газу, суть якого полягає у поглинанні НВЧ сигналу, а отжевимірюванні потужності цього сигналу на виході хвилеводу у разі зміни вологості… Show more

“…In [5], the choice of the microwave method for measuring the humidity of natural gas was justified, in which, in contrast to the known methods, the use of a traveling wave in a waveguide is proposed. In this case, changes in the dielectric properties of gases during their interaction with microwave waves are estimated.…”

“…The essence of the microwave measurement conversion of natural gas moisture is to absorb the microwave signal, and therefore measure the power of this signal at the output of the waveguide when the humidity of the gas changes by using a traveling wave. The authors proposed a mathematical model of such a microwave measuring conversion of natural gas moisture [5]. The conducted studies of the dependence of the traveling wave power on the absolute TECHNOLOGY AUDIT AND PRODUCTION RESERVES -№ 2/1(52), 2020 ISSN 2664-9969 humidity of water vapor at various values of the microwave signal transmission length in a humid environment, taking into account temperature and pressure.…”

“…The authors propose a mathematical model of an ultrahigh frequency transmitter humidity natural gas. A detailed explanation of the mathematical model is given in [5,7,10]. Research based on the power of a traveling wave from the absolute humidity of water vapor at different values of the length of the passage of the ultrahigh frequency signal in a humid environment subject to temperature and pressure is conducted.…”
