Щ U

Во-первых, тем, что траектори  шарир а проходит в  дре потока, где скорость потока, набегающего на шарик, мало отличаетс  от средней скорости по сечеиию.Firstly, by the fact that the trajectory of the sharir a passes in the heart of the stream, where the velocity of the flow incident on the ball differs little from the average velocity along the section.

Во-вторых, тем, что така  конструкци  устройства в целом обеспечивает посто нство величины эффективного проходного сечени  в кольцевой камере завихрени  в широком диапазоне измерени .Secondly, by the fact that such a design of the device as a whole ensures the constancy of the magnitude of the effective flow area in the annular vortex chamber in a wide measuring range.

В-третьих, тем, что вли ние -пограничных слоев в местах контакта шарика с кольцами мало вследствие их тонкостенности, а потому тормоз щие моменты от в зкого трени  незначительны.Thirdly, by the fact that the influence of the –boundary layers at the points of contact of the ball with the rings is small due to their thin walls, and therefore the braking moments from the viscous friction are insignificant.

Кроме того, кольца 6 контактируют с шариком в зонах отрыва вихревого следа иIn addition, the rings 6 are in contact with the ball in the zones of separation of the vortex wake and

Использование изобретени  позволит повысить точность измерени  шариковых расходомеров .The use of the invention will improve the measurement accuracy of ball-type flow meters.
