Title
(EN) Multiphase flow-mass metering device based on ray coincidence measurement
(ZH) 一种基于射线符合测量的多相流量质量计量装置
Abstract
(EN)
The invention relates to a multiphase flow-mass metering device based on ray coincidence measurement, comprising a support. A pipe through hole allowing a fluid pipe to pass through is arranged in thecenter of the support; the outer wall of the pipe through hole is provided with a plurality of ray detection components; the ray detection components are distributed along the periphery of the pipe through hole; each ray detection component includes scintillation crystal and a detector, and the scintillation crystal is positioned between the outer wall of the pipe through hole and the corresponding detector. Intrinsic ray of the scintillation crystal is utilized herein to perform full-section measurement; a radioactive source in the prior ray measuring equipment can be omitted, so that systemcost is reduced, equipment size is decreased, and system safety and reliability are greatly improved; in addition, as Lu-176 has a half-life period of 2.1*1010 years; the device herein never decreases in performance due to aging of a radiating device, and system stability is greatly improved, with service life greatly extended.
