Abstract
A submersible load cell for measuring gas buoyancy which includes a shell which has an open bottom so that gas can be introduced to make the shell positively buoyant. A framework may be provided for supporting the shell for vertical movement so that a change in buoyancy results in the shell exerting a corresponding upward force. At least one hydraulic actuator is mounted between the framework and the shell for registering a pressure which corresponds to the degree of upward force or positive buoyancy of the shell. An indicator device can be connected to the hydraulic actuator for indicating the change in buoyancy of the shell as gas is introduced therein.
