20100281999 | Method for determining measuring tube wall thickness of a coriolis, flow measuring device - 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. | 11-11-2010 |
20100281998 | Method for detecting blockage in a cariolis flow measuring device - 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. | 11-11-2010 |
