Abstract
Official abstract text for this publication.
A flow meter device comprises a flow measuring section ( 2 ) for measuring a flow of a fluid in a fluid passage through which the fluid is supplied to a fluid instrument in use; and a measurement data processing section ( 3 ) which calculates a slope of a change in a flow difference per unit time which change occurs with time, at a time point when a sign of the flow difference per unit time is inverted, based on the flow of the fluid measured by the flow measuring section, and determines whether or not the fluid instrument in use is a particular fluid instrument based on whether or not the slope falls within a predetermined range.
