Abstract
A device for total cross-section measurement of a mass flow rate of gas, liquid and solid in a multiphase flow includes a gamma-ray source, a gamma-ray detector, and a differential pressure type flowmeter. The differential pressure type flowmeter includes a throat section, and the gamma-ray source and the gamma-ray detector are respectively disposed at opposite positions on both sides of the throat section. The gamma-ray detector is an array including a plurality of detection units, and the gamma-ray source is configured to emit gamma rays covering the measurement cross-section of the throat section. The gamma-ray detector is configured to receive the gamma rays passing through the measurement cross-section of the throat section.
