A method for detecting blockage of a measuring tube of a Coriolis flow measuring device, which has at least two measuring tubes. For this, the at least two measuring tubes are excited by at least one exciter to execute mechanical oscillations, mechanical oscillations of the measuring tubes are registered by at least one sensor and at least one measurement signal representing the mechanical oscillations is produced. At least one produced measurement signal is analyzed for the occurrence of a deviation of a resonance frequency of one measuring tube relative to a resonance frequency of the at least one other measuring tube. In case such a deviation occurs, blockage of a measuring tube is established. |
