Definitions

  • the oscillation principle of the above oscillator is that the jet that is injected into the oscillation chamber by the high pressure nozzle is attached to the left partition plate 18 or the right partition plate 20 due to the Coanda effect.
  • the solid arrows in Fig. 1 indicate that the jet is attached to the left partition 18 and is thus ejected by the left output flow passage 19. While the medium velocity jet injected by the inlet pipe 15 is injected into the left output flow passage 19, a small portion is also incident on the left reflection bucket 16. After a small part of the water flow is reflected, it is rushed from the left feedback channel 17 to the right side of the nozzle outlet.
  • the vector law of momentum synthesis allows the subsequent jet to be attached to the left partition 18 and is changed to the dotted line in FIG.
  • the fairing device is a sheet-like mechanism having a plurality of fluid through holes disposed between the oscillation generator fluid path inlet and the inlet nozzle.
  • the rectifying device includes a sheet-like mechanism having a plurality of fluid through holes, and a wedge-shaped flow path having a length, the sheet-like mechanism being located between the inlet and the wedge-shaped flow path, The larger opening side of the wedge flow channel is connected to the sheet-like mechanism, and the smaller opening is connected to the oscillation generator fluid path inlet.
  • the sampling circuit board 335 and the main control circuit board 334 are powered by the battery assembly 361.
  • the upper cover 357 has a window (not labeled) that houses the display window transparent mirror 356.
  • the upper cover 357 further includes a flip cover 358 that opens the flow rate display on the main control circuit board 334 in the flow meter.
  • outlet nozzle 220 is also provided with a single flow guiding device 390 that prevents reverse flow of fluid.
  • the single-directional flow device 390 can achieve the following technical effects:

Abstract

La présente invention se rapporte à un instrument pour écoulement, ainsi qu'à un générateur d'oscillation associé. L'instrument pour écoulement comprend un générateur d'oscillation ayant un trajet de fluide, une électrode de détection située sur le générateur d'oscillation, un circuit d'échantillonnage connecté à l'électrode de détection, ainsi qu'un tuyau de liaison d'entrée et un tuyau de liaison de sortie qui sont reliés respectivement à une entrée et une sortie du trajet de fluide. Cet instrument pour écoulement comporte en outre : un dispositif de rectification qui permet de rectifier un fluide, le dispositif de rectification se trouvant à l'entrée du trajet de fluide du générateur d'oscillation, ou à l'emplacement du tuyau de liaison d'entrée, ou à n'importe quelle position entre l'entrée du trajet de fluide du générateur d'oscillation et le tuyau de liaison d'entrée ; ainsi qu'une protection pour blindage électromagnétique qui protège le circuit d'échantillonnage. Ledit instrument pour écoulement et ledit générateur d'oscillation peuvent améliorer efficacement la précision et la stabilité d'une mesure de fluide.
