ABSTRACT:
A mass flowmeter of the Coriolis type with a tube that forms a mechanically closed loop through which a medium flows during operation, and with preferably electromagnetic, contactless excitation elements for causing the loop to rotate in an oscillatory mode about an axis of rotation during operation. The loop has a starting point and an end point. The starting and end points are situated close together and are connected to a flexible inlet tube and a flexible outlet tube, respectively, which extend preferably in parallel and close together. The loop is resiliently suspended from the frame of the flowmeter via the flexible inlet and outlet tubes, which preferably form one integral piece with the tube of the loop.
