Abstract
The flowmeter of reaction type is a flowmeter by which the flow-rate of a liquid is obtained by measuring the balancing force acted on the movable tube through which the liquid flows. A device of flowmeter of this type with a cupshaped movable tube has been reported by author and others in this journal. The flowmeter of reaction type here reported is a bee-line flowmeter, in which flow-in and flow-out are of the same direction. In such a flowmeter, the areas of inlet and outlet ends must be different to each other.
Experiment are done with two flowmeters, one of them has two bellows of equal effective areas and the other of unequal effective areas.
