According to the invention, an apparatus to characterize leaks in a fluid storage container is disclosed. The apparatus may include a valve coupler, a gas manifold and a processor. The valve coupler may couple the apparatus with a closed valve on the fluid storage container. The gas manifold may be coupled with the valve coupler and may include a first branch connected with a gas monitoring device. The gas monitoring device may scan for a plurality of gases that may be emitted by the closed valve of the fluid storage container. The processor may be operable to receive gas monitoring device data representing masses for one or more of the plurality of gases detected by the monitor.

Leak characterization apparatuses and methods for fluid storage containers

According to the invention, a system for applying torque to a valve element that stops fluid flow through the valve is disclosed. The system may include an input element, a drive element, and a torque transferring mechanism. The input element may be configured to receive a torque. The drive element may be configured to apply substantially none of the torque, or at least a portion of the torque, to the valve element. The torque transferring mechanism may be configured to receive the torque from the input element, and transfer substantially none of the torque, or at least a portion of the torque, to the drive element based at least in part on a resistance of the valve element to turning.
