Abstract
This mass flow sensor has a vibration-body arrangement through which flows a fluid to be measured and which comprises the following parts: two plane, congruent tube loops each consisting of a straight inlet tube with an inlet end, a straight outlet tube with an outlet end, which ends are fixed in a common mount, and a tube bend interconnecting the respective inlet tube and the respective outlet tube. Mounted at the junctions of the respective inlet and outlet tubes and the associated tube bends is a plate with holes which correspond to the outside diameter of the straight tubes and the tube bends and in which the latter are fixed to determine a respective vibration node. A vibration exciter sets the two tube bends into opposite sympathetic vibrations perpendicular to their respective planes, and two sensors are spaced along the straight tubes for sensing the vibrations of the latter.
