Definitions

  • the ultrasonic flow measurement unit 10 has a measurement flow having an opening on one surface of a measurement flow path having a rectangular cross section orthogonal to the direction in which the fluid 60 flows.
  • the sensor unit 16 is an opening of the measurement flow path unit 15. are integrally provided adjacent to each other.
  • the first ultrasonic input / output unit 32 and the second ultrasonic input / output unit 33 formed on the first side wall 21 of the flow path body 17 are covered, for example, 20 mesh to 500 mesh.
  • An ultrasonic transmission film 34 composed of a mesh member formed in (1) is disposed. Normally, the mesh of the mesh member is selected in consideration of the attenuation of ultrasonic waves and the flow state of a fluid such as gas, and needless to say, it is not limited to the above values.
  • the ultrasonic transmission film 34 transmits ultrasonic waves transmitted and received by the pair of ultrasonic transducers, but has a function of substantially blocking the entry and exit of the fluid.
  • a punching metal member or the like can be used as the ultrasonic transmission film 34.
  • the number of the partition plates may be a configuration in which the partition plate is not provided or a configuration in which the measurement channel is divided by an arbitrary number of partition plates when the flow of fluid flowing through the measurement channel is not disturbed. Thereby, the design freedom, such as a measurement channel, can be improved.
  • the position where the flow rate calculation unit 49 is arranged is not particularly mentioned.
  • the sensor holding such as between the first transducer 42 and the second transducer 43 of the sensor unit 16 is performed. You may provide in the part 41. FIG. Thereby, an ultrasonic type flow measurement unit can be made into a more compact configuration.
  • the measurement flow path of the measurement flow path unit is divided into a plurality of flow paths by a plurality of partition plates.
  • the measurement flow path can be divided into a plurality of flow paths to be multilayered, and the flow of the fluid to be measured can be rectified.

Abstract

L'invention concerne une unité de mesure de débit à ultrasons comprenant une unité canal d'écoulement de mesure comportant une ouverture dans une surface d'un canal présentant une coupe transversale rectangulaire par lequel s'écoule un fluide à mesurer, ainsi qu'une unité capteur pourvue de deux transducteurs à ultrasons éloignés d'au moins une distance prédéterminée dans le sens du canal d'écoulement du fluide à mesurer, l'unité capteur étant disposée intégralement à travers l'ouverture de l'unité canal d'écoulement de mesure. Des réglages pour la mesure du débit peuvent ainsi être effectués aisément dans l'unité canal d'écoulement de mesure par laquelle se propagent des ondes ultrasonores.
