Abstract
A mass flowmeter and a method for operating a mass flowmeter is based on the Coriolis principle and incorporates a Coriolis measuring tube, an oscillator associated with and stimulating said Coriolis measuring tube, and a transducer associated with the Coriolis measuring tube and which collects Coriolis forces and/or oscillations based on Coriolis forces. The electric power consumed in the mass flowmeter is controlled as a function of the available electric power. This permits the efficient use of the available electric power, thus permitting the operation of the mass flowmeter via a two wire interface that serves for both the input of electric power and the output of measuring data.
