PROBLEM TO BE SOLVED: To provide a flowmeter of simple constitution capable of surely storing the information in abnormality detection as history and capable of providing to the analysis of the abnormality. SOLUTION: A flowmeter body includes: a flow sensor; a flow integration means for obtaining the integrated flow by integrating the flow detected by the flow sensor; an abnormality detection means for detecting the abnormality of the flowmeter body and/or the piping system in which the flowmeter body is built in; and a memory (storage means) for storing the integrated flow value as the abnormal history obtained by the flow integration means in abnormality detection, together with the information indicating the kind of abnormality in abnormality detection by the abnormality detection means.
