Abstract: A fluid measuring device comprises a body suspended by a force transmission means within a container for receiving the fluid to be measured. The weight of the body is counterbalanced by a tare weight acting on a lever connected to the force transmission means. A gyroscopic load cell measures the vertical force exerted on the body by the fluid in the container and is calibrated so that a load cell display expresses the quantity of fluid received discharged or existing in the container as its volume or its weight. Servo-operable inlet and outlet valves to the container can be controlled by signals from the load cell whereby the device will meter predetermined quantities of the fluid.

Abstract: A dynamometer cell consists of a gyroscope of which the precessional motion induced by the force to be measured is a measure of that force. In order to apply the force to a lever of which one end is movably mounted on an inner gyroscope gimbal while the other end is similarly mounted on an outer gyroscope gimbal a vertically rotatably mounted suspension member is provided. The non-precessing end of this suspension member includes a support member to which a load lever is hingedly attached and to which lever the force to be measured is directly or indirectly applied. With the object of avoiding or at least reducing undesirable oscillations of the lever the support member consists of at least two parts adapted to be mutually mobile by means of bearing members provided therebetween.
