  • Portable Leak Detection Instrument Improves Heat Rate at Electric Power Plant.
    ,. find the leak and get out quickly. Seminole originally tried an older airborne ultrasound detector. The unit tested was not. designed for the high humidity environment that is present in steam condensers. It soon. ceased to function as moisture built up in the circuit, but not before they were
  • Detection of Moisture within Building Enclosures by Interior and Exterior Thermographic Inspections (.pdf)
    . Moisture detection methodologies for interior and exterior inspections vary and equipment specifications are different for both types of inspections. The physical mechanisms that produce moisture patterning in the infrared wavelengths are different for both interior and exterior inspections
  • Non-Invasive Roof Leak Detection Using Infrared Thermography
    : Moisture detection, non-invasive leak detection, roof leak detection, testing criteria, infrared. thermography, building diagnostics. INTRODUCTION. Roof leaks are typically discovered by direct observation. If the roof sheathing is not visible from below, such. as in an attic, the wallboard or ceiling
  • Beta testing an in-line monitor for moisture measurement in inert gas lines
    moisture challenge, providing an accurate moisture reading at start-up. Figure 10: Responses of a prototype monitor and a pressure-compensated production model to a 7-ppbv moisture challenge. Leak Detection In another installation at Siemens, when the monitor detected moisture levels up to 100
  • Using an in-line monitor to obtain real-time moisture measurements (First of two parts)
    , and pressure regulators). Moisture in a gas line can also be an indication that a leak has occurred. Several techniques are useful for detecting moisture in process gases. However, many characteristics of these methods such as bulky instruments, slow measurement speed, and high capital costs limit
  • Fundamentals of Combustible Gas Detection
    than air and highly. flammable. Its low LFL and wide flammability range make it extremely easy to. ignite. In the presence of moisture, acetylene can react with copper, silver and. mercury to form metallic acetylides that are shock-sensitive, explosive compounds. 7. Ammonia. Used in a variety

    outgassed. In our many years of field leak detection, we have found the following problems. (starting with the most frequent). 1.) Customer's leak detector is out of calibration and not "seeing" helium. 2.) Improper leak check procedure: not using the "puff into the ballast valve test". to verify
  • Pulling Money Out of Thin Air
    a compressed-air system is in fixing air leaks. Much has been written about air leaks. However, there are new audit and detection methods worth revisiting. It is not unusual for a well-maintained plant to have a leak rate of around 20% of total compressed air production. A single 1/16-in. leak can
