摘要： This method of fixing the ends of measuring tubes in associated transition pieces of a Coriolis-type mass flow sensor eliminates the risk of stress-corrosion cracking in these areas as completely as possible. The ends of the measuring tubes are inserted into associated bores of the respective transition pieces and are press-bonded to the walls of the respective bores without heat supply using a rolling tool which is inserted into the respective ends.

摘要： 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.

摘要： The device comprises a thin vibratable plate to be introduced into the substances whose density is to be measured, and the plate is held by a holder at a holding point and is vibrated by at least one vibration exciter in operative engagement with the plate. The vibrations of the plate are detected by at least one vibration detector operatively associated with the plate at a point spaced from the point or points at which vibrations are imparted to the plate. An electronic unit is connected to the vibration exciters and the vibration detector and forms therewith an oscillator having an input from the vibration detector and an output supplied to the vibration exciters. The vibration exciters are so positioned with respect to the plate, and so energized by the electronic unit, that the plate vibrates in a manner such that two nodal lines intersect in the range of each holding point at which the plate is supported by a holder. While the plate may have various configurations, it is preferably circular and is so energized that the nodal lines extend diametrically of the plate and intersect at its center, with the center forming the holding point at which the holder supports the plate. The electronic unit includes a meter measuring the periods of the vibration.
