  • Page 17: Theory Of Operation

    Description 3.3 Theory of operation Theory of operation The FVA250 operates according to the principle of flotation. The flowing measuring substance raises the conical float in the measuring ring. In this way the annular gap widens until an equilibrium between the buoyancy of the measuring substance and the weight of the float is achieved.
