Abstract
1. Способ измерения расхода жидкой среды, заключающийся в том, что внутри трубопровода помещают, перемещают и поляризуют жидкую среду, отличающийся тем, что в колебательном контуре, который содержит катушку индуктивности колебательного контура и конденсатор колебательного контура, возбуждают свободные затухающие резонансные колебания электромагнитного поля, перемещают жидкую среду в магнитном поле, поляризуют жидкую среду под действием силы Лоренца, вследствие этого изменяют электрическое поле конденсатора колебательного контура в жидкой среде, диэлектрическую проницаемость жидкой среды, емкость конденсатора колебательного контура, а также длительность первого и второго полупериодов периода свободных затухающих резонансных колебаний электромагнитного поля колебательного контура, измеряют длительность и амплитуду первого или второго полупериодов периода свободных затухающих резонансных колебаний электромагнитного поля колебательного контура, а расход жидкой среды измеряют за счет изменения амплитуды первого полупериода периода свободных затухающих резонансных колебаний электромагнитного поля колебательного контура в момент первого максимума длительности первого полупериода периода свободных затухающих резонансных колебаний электромагнитного поля колебательного контура или за счет изменения амплитуды второго полупериода периода свободных затухающих резонансных колебаний электромагнитного поля колебательного контура в момент первого минимума длительности второго полупериода периода свободных затухающих резонансных колебаний электромагнитного поля колебательного контур1. The method of measuring the flow rate of a liquid medium, which consists in the fact that a liquid medium is placed, moved and polarized inside the pipeline, characterized in that free damped resonant vibrations of the electromagnetic field are excited in the oscillating circuit, which contains the inductor of the oscillating circuit and the capacitor of the oscillating circuit, move the liquid medium in a magnetic field, polarize the liquid medium under the action of the Lorentz force, as a result of which the electric field of the oscillator circuit capacitor is changed into in a fluid, the dielectric constant of a liquid medium, the capacitance of an oscillator circuit capacitor, as well as the duration of the first and second half-periods of a period of free damped resonant oscillations of an electromagnetic field of an oscillatory circuit, measure the duration and amplitude of a first or second half-period of a period of free damped resonant oscillations of an electromagnetic field of an oscillatory circuit, and the flow rate liquid medium is measured by changing the amplitude of the first half-period of the period of free decaying reson ns oscillations of the electromagnetic field of the oscillatory circuit at the time of the first maximum duration of the first half-period of the period of free damped resonant oscillations of the electromagnetic field of the oscillatory circuit or due to a change in the amplitude of the second half-period of the period of free damped resonant oscillations of the electromagnetic field of the oscillatory circuit at the time of the first minimum duration of the second half-period of the period of free damped resonant oscillations electromagnetic field oscillatory circuit
