A method for checking a connection seal between two elements of a part, includes dipping the part to be checked in a penetrant having a compound suitable for reacting to light excitation; cutting the part at the connection to be checked; and checking for the presence of penetrant under a light capable of exciting the penetrant.

A scour monitoring system may provide a housing that is separated into multiple segments that are fluidically isolated from each other. The scour monitoring system may be position adjacent to a structure to be monitored for bridge scouring. Each of the segments may provide a water-swellable material positioned near or in contact with a fiber Bragg grating (FBG) cable. If water penetrates a segment, the water-swellable material may expand to deform the FBG cable. The wavelength of the FBG cable may be monitored periodically for changes, thereby providing moisture detection when a change in wavelength is detected.

A forced air leakage testing assembly includes a plurality of intake covers that can each be fitted over an air intake of a respective type of air handler of a forced air heating and cooling system. A flange is attachable to a respective one of the plurality of intake covers and the flange is attachable to an exhaust hose of a source of forced air to direct forced air into the air intake over which the respective intake cover is positioned. A plurality of register covers is each positionable over a respective air register thereby inhibiting air from flowing through the respective air register. A balloon is inflatable to seal a floor register when the balloon is inserted into the floor register and inflated thereby inhibiting air from exiting the floor register.

An above ground pipe is installed at a location to transport fluid for one or more operations. A fiber optic cable is laid on the above ground pipe and temporarily attached to the above ground pipe. The fiber optic cable is laid on the above ground pipe with a sinusoidal curvature to increase contact between the fiber optic cable and the above ground pipe. Leaks along the above ground pipe are detected using measurements from the fiber optic cable. The fiber optic cable is removed from the above ground pipe for re-use at a different location.

A method of determining a flow rate of a gas leak in a pressurized gas system includes applying a liquid soap solution to a region of a component, and capturing, via a camera of a portable electronic device, a plurality of sequential images of bubbles formed in the region by an interaction between the liquid soap solution and a gas leak from the component. The plurality of images are analyzed by a first algorithm executed by a processor to determine a total area of the bubbles in the region produced by the leak. A flow rate of the gas leak is then determined via a second algorithm executed by the processor based on the total area of bubbles in the region, a size of the component, and a pressure of the gas.
