Abstract
A method for determining tube wall thickness of at least one measuring tube of a Coriolis, flow measuring device, wherein the Coriolis, flow measuring device has an oscillatory system, which includes at least one measuring tube, and at least one exciter, by which the oscillatory system is excitable to execute mechanical oscillations. In the method, at least one excitation input variable of the at least one exciter and at least one response variable of oscillations of the oscillatory system caused thereby are registered. Additionally, a tube wall thickness of the at least one measuring tube is ascertained by inserting the excitation input variable and the response variable into a transfer equation.
