Wet Gas Flow Measurement Based on Differential Pressure Pulsation of Tapered Orifice Plate

Through having differential pressure pulsation considered,a tapered orifice plate which boasting of anti-blocking property was designed to measure two parameters of wet gas flow at a constant pressure.Using mature theory of differential pressure pulsation for reference,the SVM was applied and the R and x were taken as input variables and the dryness as output value to obtain dryness measurement model under a changeable pressure.The experimental results show that this measurement method can be applicable to dryness measurement at wet gas condition and gas-liquid flow measurement at non-wet-gas condition.
