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.
