摘要： PROBLEM TO BE SOLVED: To suppress flow measurement error in a volumetric flowmeter in which a measurement element for allowing a constant amount of fluid to flow in each cycle is repeatedly operated for measuring a flow.SOLUTION: A volumetric flowmeter comprises: a measurement element for allowing a constant amount of inflow fluid to flow in each cycle by circulatively repeating an operation in a channel; a differential pressure detector for detecting a differential pressure between the fluid flowing into the measurement element and the fluid flowing out of the measurement element; an operation detector for outputting a signal in accordance with the operation of the measurement element; a motor for assisting the operation of the measurement element; a waveform generating part for generating, on the basis of the output signal of the operation detector, a waveform including a frequency component over a response frequency of the differential pressure detector; and an operation control part for controlling, on the basis of the differential pressure detected by the differential pressure detector and the waveform generated by the waveform generating part, an operation of the motor so that the differential pressure between the fluid flowing into the measurement element and the fluid flowing out of the measurement element may be zero.
