A bearingless windmill-type gas flowmeter was developed, and its characteristice are described with both theoretical explanation and experimental results. The windmill is mounted on a float, and the float is on liquid in a cup so that the friction against the rotation of the windmill due to friction of the float to liquid is reduced to be negligible at slow rotating speeds. To keep the axie of rotation of the windmill assembly to the center, a magnetic attraction is introduced. The flowmeter shows a satisfactorily linear relationship between rotating speed and flow rate over a wide range from 15 to 500 l/min.
