Abstract
A Coriolis mass flowmeter that incorporates a straight Coriolis measuring tube, two straight connecting pipes, at least one oscillator stimulating the tube, a measuring sensor associated with the tube and a compensating cylinder, where the tube is positioned within the cylinder, the two end sections of the cylinder are solidly connected to the respective end sections of the tube, the tube transitions with either end section into a connecting pipe, the connecting pipes extending outside the compensating cylinder, and by means of mounting flanges provided on the external ends of the connecting pipes, the mass flowmeter can be installed in a pipeline system. Each connecting pipe meets the requirements of the formulawhere M is the mass of the cylinder, f is the natural frequency of the water-filled tube, e is the modulus of elasticity of the connecting pipes, i is the geometric moment of inertia of the connecting pipes and l is the length of the connecting pipes.
