Abstract: A mass flowmeter is described and depicted that operates according to the Coriolis principle, with a straight Coriolis tube that conducts the flowing medium, with an oscillation driver, assigned to the Coriolis tube and which excites the Coriolis tube, with two detectors assigned to the Coriolis tube and which register Coriolis forces, or Coriolis oscillations caused by Coriolis forces, and with shell that encloses the Coriolis tube. The mass flowmeter has a notably smaller total length relative to the nominal length of the Coriolis tube than mass flowmeters made according to the prior art because the Coriolis tube is flexibly mounted to an inlet and outlet in the shell.

Abstract: A mass flowmeter for flowing media, which operates according to the Coriolis principle, has a preferably cylindrical housing, at least one preferably essentially straight Coriolis measuring tube located within the housing and connected at both of its ends to the housing, a preferably cylindrical bridge located on the Coriolis measuring tube, at least one oscillation generator acting on the Coriolis measuring tube, and at least one sensor detecting Coriolis forces and/or Coriolis oscillations based on Coriolis forces, the bridge being located symmetrically and designed symmetrically with respect to the mid-point of the Coriolis measuring tube, wherein the midpoint of the Coriolis measuring tube is defined with reference to the ends of the Coriolis measuring tube connected to the housing, and the oscillation generator and the sensor being operative between the Coriolis measuring tube and the bridge, The flowmeter is characterized by the fact that the bridge is provided with a balancing system located essentiall

Abstract: A preamplifier for amplifying signal voltages from a signal source with high source impedance has a signal input connected to the signal source, a first supply voltage terminal connected to the first power supply voltage potential, a second supply voltage terminal connected to a second power supply voltage potential and a signal output supplying an output signal. In this preamplifier, the first and second power supply voltage potentials can be shifted in parallel depending on the output signal. Alternatively or cumulatively, a known preamplifier may be developed so that the potential of a shield for the signal source can be controlled by the output signal.
