Abstract
This paper discusses an applicaton of the hydraulic oscillator utilizing the self -exited vibration phenomenon to a flowrate meter which detects the flowrate in the form of a vibratory member frequency.
The hydraulic oscillator is constituted not to cause the pulsation of the flowrate when the fluid passes through it, and the frequency characteristics are improved to confom with a flowrate meter.
The approximated equations of motion for the vibratory member are obtained and solved by means of digital computer.
The experiments are conducted by varying the ratio of a main spring constant to an auxiliary spring constant. The experimental frequency characteristics almost agree with the theoretical. It is confirmed by the theoretical and experimental study that the hydraulic oscillator is applicable to a flowrate meter.
