We have frequently experienced large amplitude vibration of floats of float-area-type flow meters. Nevertheless, elements generating unsteady flow have not been installed through pipelines when employing gases as working fluids. This kind of instability has been considered to be most dangerous when using the float-area-type flow meters. In order to clarify factors influencing this kind of float instability of the float-are-type flow meters, a theoretical study was performed in this paper by adopting a simple model which consisted of a float-area-type flow meter and a circular pipe installed upstream. The theoretical results were verified by experiments of self-excited vibration of the float, which were carried out by varying the length of the circular pipe and air as the working fluid. Good agreement was ascertained between the theoretical and the experimental results.
