An apparatus to detect fluid sealing of fuel tank includes a flow inlet and a flow outlet. The apparatus also includes a first flow path, fluidly connected between the flow inlet and the flow outlet, where the first flow path includes a fluid pump which pressurizes fluid from the flow inlet, the first flow path including an on-off valve to allow flow from the flow inlet to the flow outlet, the first flow path including a pressure sensor, and a flow control orifice located in the first flow path between the check valve and the flow outlet. The apparatus also includes a second flow path fluidly connected between the flow inlet and the flow outlet, the second flow path including an on/off valve located therein.

A portable, case-enclosed pressure test manifold, configured to support both pneumatic and hydrostatic pressure testing, and comprising a downstream fluid path (e.g., a test gauge, a vent valve, a system test port, a relief valve, and various other high-pressure rated components/piping) and an upstream fluid path (e.g., a low-pressure gauge, a high-pressure gauge, and various other low-pressure rated components/piping). A regulator and/or the vent valve selectively operate the downstream fluid path, defining a high-pressure fluid path, to receive a liquid; and the upstream fluid path in combination with the downstream fluid path, defining a low-pressure fluid path, to receive a gas. Manifold components are pressure rated based on use and are ASME Code B31.3 compliant. A flexible hose connects with either of the low-pressure fluid path and the high-pressure fluid path of the manifold. The case includes parking receptacles and a carrying handle configured to stow the hose during transport.

Exemplary embodiments disclosed herein are directed to systems and methods by which the contents of a container, such as the level of liquid nitrogen in one or more liquid nitrogen storage containers, can be locally and/or remotely monitored, and alerts can be generated if a leak is detected. The weight of the container, or a combination of the weight and the temperature of the container, may be monitored with respect to detecting a leak.

Systems and methods for determining Container Closure Integrity (CCI) in a container system comprising a container, an elastomeric stopper, and a retainer for retaining the stopper in place are disclosed. The systems and methods involve disposing, within a seal assembly, a component configured to sense a degree of compression of the elastomeric stopper. In a first implementation, the elastomeric stopper comprises an embedded positioning component embedded within the elastomeric material. The position of the positioning component is sensed using a detection system and the integrity of the closure is determined based on the position of the embedded component. In a second implementation, a force sensitive resistor is disposed within the seal stack to measure the compression of the elastomeric stopper. The compression of the elastomeric stopper is correlated to the integrity of the seal.

A coupling for use with a blower unit for detecting leaks in a structure, wherein the coupling is constructed and arranged to attach to a surface of the structure defining an opening and to the blower unit via a sealing gasket, and to allow air flow through the coupling when the blower unit is attached to the coupling and to prevent air flow through the coupling when the blower unit is not attached to the coupling, and wherein the coupling further includes a pressure port defined within a surface of the coupling constructed and arranged to accommodate at least one of a differential pressure gauge fitting or a tube.

In one embodiment, systems and methods include using a pressure measurement and leak test tool to measure the internal pressure of a container. A pressure measurement and leak test tool comprises a first side, a second side, a top end, a bottom end, and a front surface. The first and second side are disposed along the same plane opposite from each other, wherein the top and bottom end are coupled to the first and second side, wherein the top and bottom end are disposed opposite from each other, wherein the front surface is disposed on an edge defined by the first side, the top end, the second side, and the bottom end. The pressure measurement and leak test tool further comprises an electrical connector disposed on the top end, a power switch disposed on the front surface, and an information handling system comprising a display disposed in the front surface.

A leakage detector for a fuel vapor treatment device includes a fuel vapor treatment device that maintains the interior of a treatment system of the fuel vapor treatment device in a sealed state. In addition, the leakage detector includes; a closing valve and shutoff valve that can shut off fluid communication between the fuel tank and the canister to section the interior of the treatment system into a first region including the fuel tank and a second region including the canister. Further, the leakage detector includes an aspirator that applies a negative pressure to the second region. The leakage detector for the fuel vapor treatment device determines the presence and/or absence of leakage in the first region on the basis of a change in the pressure in the first region while an engine is stopped and determines the presence and/or absence of leakage in the second region on the basis of a change in the pressure in the second region by applying a negative pressure to the second region while the engine is operated.

This disclosure relates to equipment utilized to manufacture chemical agents, particularly biopharmaceuticals, using Disposable Containers (DCs).

The present invention discloses a dual mode fuel tank leakage detector (100), comprising of an electromechanical valve (1) with a canister port, an engine control unit, pump assembly, a sensor (3) and works in pressure condition by comparing a measured pressure with reference pressure; in case there is leakage then the pressure is not upto the reference pressure within time interval. In case of no leakage, the pressure will be equal/above than the reference pressure, the leakage detector (100) works in vacuum condition by comparing a measured leakage with a reference leakage, in case there is a leakage the measured vacuum is not able to reach to the reference vacuum within a time interval and when there is no leakage, the measured vacuum will be equal or above from the reference vacuum and fuel tank leakage detector (100) enables to monitor leakage detection either in vacuum or pressure conditions.

Exemplary embodiments disclosed herein are directed to systems and methods by which the level of liquid nitrogen in one or more liquid nitrogen storage containers can be monitored, leaks may be detected and reported, and ideal container fill level may be indicated.
