摘要
A Coriolis mass flow measuring device includes four bent measuring tubes, two exciter mechanisms, and two sensor arrangements. All four measuring tubes are joined inlet end and outlet end with collectors, where the measuring tubes are connected inlet end and outlet end pairwise with node plates to form oscillators, where the exciter mechanisms are adapted to excite bending oscillation working modes between the two measuring tubes of an oscillator, where the first oscillator and the second oscillator have bending oscillation working modes with first and second working mode eigenfrequencies (f11, f12), where the magnitude of the difference of the working mode eigenfrequencies of the two oscillators (|f11−f12|) amounts to at least 0.1 times, for example, at least 0.2 times and especially at least 0.4 times the lower of the two working mode eigenfrequencies, where the sensor arrangements are adapted to register oscillations of the oscillators.
