Abstract
A mass flow meter has a high inertial support. A fluid conduit is fixedly mounted on the support. The conduit has a symmetrical portion and a flexible connecting portion. The connecting portion is interposed between the support and the symmetrical portion. The symmetrical portion has a geometric center and an axis through the geometric center. A housing is rigidly affixed to the symmetrical portion. A rotor is rigidly mounted for rotation within said housing. The rotor is located at the geometric center and is perpendicular to the axis. The rotor is maintained at the geometric center and perpendicular to the axis at all times during the operation of said meter. A device is varying rotational speed of the rotor is operatively connected to the rotor. A mechanism for oscillatory driving the housing and its contents about said axis is operatively connected to the symmetrical portion. A mechanism for sensing movement of the symmetrical portion is operatively connected to said symmetrical portion. A mechanism for determining the rotational speed of the rotor is operatively associated with the rotor.
