Description

иитным Полем в области обтекател  образуетс  электрическое поле. Поскольку магнитное поле с двух сторон обтекател  имеет разное направление, то разность потенциалов между электродами 3 от основного потока практически равна нулю. При этом предполагаетс , что обтекатель расположен в трубопроводе симметрично.An electric field is formed in the field of a winding field. Since the magnetic field on both sides of the winding has a different direction, the potential difference between the electrodes 3 from the main flow is almost zero. In this case, it is assumed that the fairing is positioned symmetrically in the pipeline.

В результате нарушени  симметрии распределени  скорости потока, возникающего при по влении вихр , между электродами 3 возникает сигнал. Поскольку вихри образуютс  с определенной частотой, .на электродах 3 возникает сигнал с той же частотой, т. е. пропорциональный расходу.As a result of the violation of the symmetry of the distribution of the flow velocity that occurs when a vortex appears, a signal arises between the electrodes 3. Since the vortices are formed with a certain frequency, a signal with the same frequency is generated on the electrodes 3, i.e. proportional to the flow rate.

Амплитуда сигнала пропорциональна индукции магнитного пол  и скорости вихр .The amplitude of the signal is proportional to the induction of the magnetic field and the velocity of the vortex.
