The total and of the pitot tube were measured when the opening of the regulating valve was changed with keeping the flowrate fixed as well as unchanged the opening of the regulating valve with invariable flowrate. Then, the dynamic pressure signals were analysed with the method of PSD after computed and normalized and a better result of frequency-domain distribution was obtained. In addition, the average energy was defined and used for the analyzing of disturbance signals of regulation valve.
