<P>PROBLEM TO BE SOLVED: To provide a flowmeter which enables an installation operator to easily determine whether or not pulsation with predetermined size is generated when the flowmeter is installed. <P>SOLUTION: A flowmeter includes: a flow rate measurement part 3 which can measure instantaneous flow rate q of fluid; a first measurement system when pulsation is small; and a second measurement system when the pulsation is large, can automatically switch measurement systems according to the size of the pulsation, and can operate in a measurement mode for measuring the instantaneous flow rate q in time series, and a pulsation detection mode for measuring the instantaneous flow rate q in time series and determining of the pulsation. The pulsation detection mode includes pulsation detection starting means for manually starting an operation in the pulsation detection mode and fixing measurement in the pulsation detection mode in the first measurement system. <P>COPYRIGHT: (C)2013,JPO&INPIT |
