Abstract

A method and flow measuring device for ascertaining flow of a medium through a measuring tube based on at least a first measurement signal, which depends at least on the flow velocity of the medium in the measuring tube, wherein the first measurement signal is registered, wherein an additional, second measurement signal is registered, which depends on the flow cross sectional area of the medium in the measuring tube and is independent of the flow velocity of the medium in the measuring tube, and wherein flow is ascertained as a function of the first and second measurement signals.
