ABSTRACT:
A flow rate measuring instrument comprising an oscillation assembly causing self-oscillation responsive to the flow condition of a fluid and a mechanism for adjusting the moment of inertia of the oscillation assembly in response to the variations in the flow condition and other conditions of the fluid, being capable of carrying out required corrections responsive to the changes in the density, level and the like of the fluid for obtaining the true flow rate of the fluid from a detected flow rate on the basis of the detection of the frequency of the oscillation assembly.
