№ 127077№ 127077

а-угол между осью звукопровода н перпендикул ром к оси трубопровода; ho-показатель преломлени  ультразвуковых колебаний, равиый отношению скоростей распространени  ультразвуковых колебаний в контролируемой Среде и -материале звзкопровода; -температурные коэффициенты скорости ультразвука соответственпо в материале звужапровода и контролируемой среде.a is the angle between the axis of the sound duct n perpendicular to the axis of the pipeline; ho-refractive index of ultrasonic oscillations, rabbi to the ratio of the propagation speeds of ultrasonic oscillations in a controlled environment and a conduit; -the temperature coefficients of ultrasound velocity are correspondingly in the material of the zvuzhvoda and controlled environment.

Выполнение этого услови  в широком диапазоне изменений акустических характеристик контролируемой среды может быть обеспечено путем Подбора материала звукопровода с определенными акустическими характеристиками и соответствуюш его расчета угла а.The fulfillment of this condition in a wide range of changes in the acoustic characteristics of the controlled medium can be ensured by selecting the sound guide material with certain acoustic characteristics and its corresponding calculation of the angle a.

Claims (2)

1.Ультразвуковой расходомер, например, дл  пульп, агрессивных и кристаллизующихс  жидкостей, основанный на измерении разности фаз ультразвуковых колебаний, проход щих через поток под острым и тулым углами от расположенных на поверхности трубопровода пьезопреобразователей со звукопроводами, отличающийс  тем, что. с целью компенсации температурных погрешностей измерени , обусловленных температурной зависимостью скорости ультразвука, угол наклона звукопровода к трубопроводу и температурный коэффициент материала звукопровода выбраны дл  каждой среды такими, что изменение скорости ультразвука компенсируетс  протиеоположно -направленным изменением акустической длины хода.1. Ultrasonic flow meter, for example, for pulps, corrosive and crystallizing liquids, based on measuring the phase difference of ultrasonic vibrations passing through the flow at acute and thick angles from piezo transducers with sound ducts located on the surface of the pipeline, characterized in that. In order to compensate for temperature measurement errors caused by the temperature dependence of the ultrasound velocity, the slope angle of the duct to the pipeline and the temperature coefficient of the duct material are selected for each medium such that the change in ultrasound velocity is compensated by oppositely directed acoustic path length variation. 2.Устройство по п. 1, отличающеес  тем, что, с целью предотвращени  «зарастани  внутреннего сечени  датчика расходомера, зву-копровод выполнен заподлицо с внутренпей поверхностью трубопровода .2. The device according to claim 1, characterized in that, in order to prevent the overgrowth of the internal cross section of the sensor of the flow meter, the sound conductor is made flush with the internal surface of the pipeline.
