    The rapid development of tomography methods particularly electrical, X and gamma rays allows for a wide range of the information about flow structure. However, all of such methods are quite complicated. At the same time much simpler systems as the measuring system of gamma rays absorption, allows to obtain a all key flow information which describe the two-phase flow. In the article the results of analyzes of radiometric signal...

  • Signal Processing in the Investigation of Two-phase Liquid-gas Flow by Gamma-ray Absorption

    Publication

    - Year 2019

    n this paper, the use of the gamma-absorption method applied in the investigation of the two-phase liquid-gas flow in the pipeline is described. An example of its application to the air transported by water in a horizontal pipeline is evaluated. In the measurements, Am-241 radioactive sources and probes with Nal (Tl) scintillation crystals have been used. The signals from the radiometric set were used to determine the velocity...

  • EVALUATION OF LIQUID-GAS FLOW IN PIPELINE USING GAMMA-RAY ABSORPTION TECHNIQUE AND ADVANCED SIGNAL PROCESSING

    Publication

    - Metrology and Measurement Systems - Year 2021

    Liquid-gas flows in pipelines appear in many industrial processes, e.g. in the nuclear, mining, and oil industry. The gamma-absorption technique is one of the methods that can be successfully applied to study such flows. This paper presents the use of thegamma-absorption method to determine the water-air flow parameters in a horizontal pipeline. Three flow types were studied in this work: plug, transitional plug-bubble,...

  • Two-phase water-air flow measurement using gamma-ray absorption technique – plug flow

    Open Research Data
    open access

    The attached datasets contains the measurement results of the air-water flow in a horizontal pipeline. Flow type: plug flow. The data shows the pulse counts of the two radiometric sets. Each of these kits consisted of a QSA Global Am-241 gamma ray source and a Tesla SKG-1 type NaI(Tl) scintillation probe. The pulses were recorded using a dedicated EC...
