A method of operating a flowmeter and to this effect flowmeter

Described and illustrated is a method of operating a flowmeter (1) comprising a measuring tube (2), said flow (d) of a medium (4) through the measuring tube (2) is measured. The invention has for its object to provide a method of operating a flowmeter (1), in which a measurement error is equal to zero at least reduced by a zero flow. The object is solved, is assigned to that in each case a continuous residence time of the measured flow (d) rvall (At
