  • Flow rate measurement method for spiral throttling component
    Patent number: 12560463
    Abstract: A flow rate measurement method for a spiral throttling component is provided, where a spiral flow channel is formed inside the spiral throttling component, and the method includes: introducing a calibration medium into the spiral throttling component, obtaining a plurality of flow rates Qv, diameter of the spiral flow channel d, effective length L of the spiral flow channel, pressure drop DP of a fluid flowing through the spiral flow channel, and density of fluid density ?, figuring out a relationship of k=f(Qv, d, L, DP and ?) to obtain a calculation formula of the flow rate Qv. Through the technical solution, a calculation formula for the spiral flow channels with different sizes can be obtained by using a small amount of calibrations, thereby avoiding mismatch of flow formulae when a size of the spiral flow channel changes.
