| 摘要 |
The invention relates to a mass flow meter which operates on the coriolis principle. The meter has two straight and parallel measuring tubes with two axially aligned compensating supply and discharge tubes arranged in parallel to the measuring tubes. The compensating tubes have approximately the same coefficient of expansion as said measuring tubes. A mounting member having supply and discharge passage has the juxtaposed ends of the compensating tubes connected thereto. The opposite ends of the compensating tubes connect to the respective juxtaposed ends of the measuring tube. An oscillator drives the measuring tubes in opposite directions and sensors are provided for detecting movements of the measuring tubes from which mass flow can be determined.
