Sinusoid based calibration for holdup measurement in two-phase flow using helical capacitance sensor

A helical capacitance sensor was designed to measure the holdup of two-phase stratified flow in horizontal pipe. The structure of 360° twisted helical capacitance sensor had been designed, analyzed and optimized using finite element method. A sinusoidal function was observed as the relationship betw...
