Imaging system for measuring multiphase flow and deposit thickness
A recently granted patent (Publication Number: US11971282B2) discloses an innovative imaging system designed to measure flow rates of individual phases in a multiphase flow, such as gas and liquid, while also providing images of the flow. The system includes an ultrasonic array imaging system with rings of ultrasonic elements that can operate in transit and/or reflection mode to determine gas phase thickness and water-cut value, as well as perform image reconstruction using tomography techniques. Additionally, the system can measure the thickness of deposits on the internal pipe wall, enhancing its utility in various industrial applications.
Furthermore, the imaging system may incorporate a THz imaging system to measure gas void fractions above a predefined value, providing additional insights into the multiphase flow. The THz imaging system, comprising a THz source and camera, can capture images reflecting the permittivity of the flow, which are then processed to determine parameters like water-cut, density, and velocity of the liquid-gas interface. The system's versatility is further enhanced by the inclusion of ultrasonic sensors operating in transit time or Doppler-effect mode, pressure sensors for flow rate measurement, and online flow conditioners like swirl separators. Overall, the patent outlines a comprehensive method for analyzing multiphase flows in pipes, offering a valuable tool for industries dealing with complex fluid dynamics.
