摘要： A meter for a liquid, such as water, comprises a measuring circuit (55) for measuring those measuring periods in response to a detection pulse sequence resulting from rotation of a body (30) rotated by the liquid, each of which may be defined either by a period of one complete rotation of the body or a predetermined interval, such as six seconds. The circuit produces measurement signals representative of individual amounts of the liquid used with the individual amounts accompanied by detection errors resulting from a variable flow rate of the liquid. A totalizing circuit (61), which may comprise an ROM or consist of a microcomputer, totalizes the individual amounts with the detection errors reduced.
