摘要： A method for detecting accretion or abrasion on a first measuring tube of a flow measuring device. A first temperature as a function of time is registered via a first temperature sensor, which is arranged on the first measuring tube in such a manner that, between the first temperature sensor and the medium, at least one measuring tube wall of the first measuring tube is embodied. Parallel in time, a second reference temperature as a function of time is registered by a second temperature sensor, which is spaced from the first temperature sensor and thermally coupled to the medium. Therefrom, at least one variable characteristic is determined, and accretion or abrasion on the first measuring tube is detected, if the at least one determined characteristic variable or a variable derived therefrom deviates by more than a limit value from a predetermined reference variable.

摘要： 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.

摘要： An inline measuring device comprises a vibratory-type transducer and a measuring device electronics electrically coupled with the vibratory-type transducer. The vibratory-type transducer includes at least one measuring tube being inserted into the course of a pipeline and serving for conducting a mixture to be measured. An exciter arrangement acting on the measuring tube for causing the at least one measuring tube to vibrate and a sensor arrangement sensing vibrations of the at least one measuring tube and delivering at least one oscillation measurement signal representing oscillations of the measuring tube. The measuring device electronics delivers an excitation current driving the exciter arrangement. Further, the inline measuring device electronics is adapted to produce a measured value representing the physical, measured quantity of the mixture to be measured. Therefor, the measuring device electronics estimates from the excitation current and from said at least one oscillation measurement signal a Coriolis coupling coefficient. This Coriolis coupling coefficient corresponds with an instantaneous coupling between a first natural eigenmode of the measuring tube currently driven by the exciter arrangement and a second natural eigenmode of said measurement tube. In this second eigenmode the measurement tube has an eigenform corresponding with a mode of vibration caused by Coriolis forces induced in the flowing mixture. Due to a variation of a concentration of at least one of a component of the mixture the Coriolis coupling coefficient varies in time.

摘要： A method for detecting complete or partial plugging of a measuring tube of a Coriolis flow measuring device, which is insertable into a pipeline, and which has a measuring transducer of the vibration type having at least two measuring tubes connected for parallel flow. The method includes, in such case, the steps of measuring a subset flow occurring in a subset of the measuring tubes, and comparing a subset flow value obtained from this measurement with a reference value to be expected for this subset. The reference value is, in such case, determined from a total mass flow determined in the context of a Coriolis mass flow measuring. Additionally, the method includes the step of detecting plugging of at least one measuring tube of the measuring transducer, if the subset flow value deviates from the reference value by more than a limit value.
