ABSTRACT:
An apparatus for measurement of density, particularly of liquids and gases, by determination of the characteristic frequency of a tube-shaped bending-type oscillator which is filled with the measuring substance, which oscillator is connected with a tensioned body, the tension of which is dependent upon the temperature and/or the pressure of the measuring substance. The tensioned body is bending-slack (a string). A member is provided which guarantees that the deflection of the bending oscillator is transmitted to the string and the restoring force of the string is transmitted to the oscillator.
