摘要： 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.

摘要： 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.
