PENNSTATE Department of Energy and Mineral Engineering Spring 2014 PSU PennTAP Air Leak Analyzer Overview Formulate a design and create a prototype device that can capture and quantify the amount of air that is leaking from various shapes and sizes of compressed air line leaks. The device will need to be flexible enough to fit and seal around various types of fittings, nozzles, hoses, small pipelines, etc. It will also needed to have some type of volumetric container or capacity that can quantitatively measure air volume escaping the leak. Objectives This design project called for the production of a device that was capable of quantifying leaks that occur in air delivery systems. This highly flexible and durable design was focused on endpoint leak quantifications, creating an airtight seal on pneumatic tools, gauges etc. Approach The costumer needs were gathered during the first meeting with our sponsor, a document outlining the objectives of the prototype was given to each team member. There are currently no patented air leak analyzers on the market, however we examined patents for similar devices, such as leak detectors and flow meters. We visited the West steam plant on campus to examine air leaks in an industrial setting. Design concepts were generated using brainstorming techniques based on the leaks we examined during our onsite visit. We created a CAD drawing for the original design concept, a Velcro prototype. An original prototype was produced utilizing Velcro and shower curtain liner, a second and final prototype was created using the Baja dry bags. We tested the device on a simulated leaking air hose. We determined that our model worked best on large leaks, and that more development would be required for a universal leak detector. Outcomes Device for quantifying endpoint leaks Basis for further development of more versatile leak capture device Potential energy and air delivery system audit for Anvil International Detailed method for instantaneous measure of air leaks

PSU PennTAP Air Leak Analyzer

Overview Formulate a design and create a prototype device that can capture and quantify the amount of air that is leaking from various shapes and sizes of compressed air line leaks. The device will need to be flexible enough to fit and seal around various types of fittings, nozzles, hoses, small pipelines, etc. It will also needed to have some type of volumetric container or capacity that can quantitatively measure air volume escaping the leak. 

Objectives This design project called for the production of a device that was capable of quantifying leaks that occur in air delivery systems. This highly flexible and durable design was focused on endpoint leak quantifications, creating an airtight seal on pneumatic tools, gauges etc.  Approach ● The costumer needs were gathered during the first meeting with our sponsor, a document outlining 

the objectives of the prototype was given to each team member. ● There are currently no patented air leak analyzers on the market, however we examined patents for 

similar devices, such as leak detectors and flow meters. ● We visited the West steam plant on campus to examine air leaks in an industrial setting. ● Design concepts were generated using brainstorming techniques based on the leaks we examined 

during our on­site visit. ● We created a CAD drawing for the original design concept, a Velcro prototype. ● An original prototype was produced utilizing Velcro and shower curtain liner, a second and final 

prototype was created using the Baja dry bags. ● We tested the device on a simulated leaking air hose. ● We determined that our model worked best on large leaks, and that more development would be 

required for a universal leak detector.

Outcomes ● Device for quantifying endpoint leaks ● Basis for further development of more versatile leak capture 

device ● Potential energy and air delivery system audit for Anvil 

International ● Detailed method for instantaneous measure of air leaks
