Abstract
A measuring system comprises a measuring and operation electronic unit (ME) and a transducer device electrically coupled thereto. The transducer device has two tubes through which a fluid flows and causes to vibrate, a vibration exciter, two vibration sensors on the inlet and outlet sides, respectively, for generating vibration signals, and an inlet-side temperature sensor coupled to a wall of the tube for thermal conduction and an outlet-side temperature sensor coupled to a wall of the tube for generating temperature measurement signals. The measuring and operation electronic unit feeds electrical power into the vibration exciter in order to effect mechanical vibrations of the tube. Furthermore, the ME generates a mass flow sequence, by means of each of the vibration signals and each of the temperature measurement signals in such a way that mass flow measurement values are independent of the temperature difference.
