发明名称 MEASURING AND OPERATING CIRCUIT FOR A CORIOLIS MASS FLOWMETER
摘要 According to the invention, a digital processor (DSP) is provided in a measuring and operating circuit for a Coriolis-type mass flowmeter. From the vibration sensor signals, said digital processor evaluates only the differential signal (D) a nd the one sensor signal (S1). The in-phase component (I) and the quadrature components (Q) are determined for the differential signal (D), and the amplification of the second sensor signal (S2) is controlled in such a manner that the in-phase component (I) vanishes. The mass flow rate (m) is determined from the quadrature component (Q).</SDO AB>
