  2. Helium mass spectrometer - Wikipedia

    en.wikipedia.org/wiki/Helium_mass_spectrometer

    Helium mass spectrometer. A helium mass spectrometer is an instrument commonly used to detect and locate small leaks. It was initially developed in the Manhattan Project during World War II to find extremely small leaks in the gas diffusion process of uranium enrichment plants. [ 1 ] It typically uses a vacuum chamber in which a sealed ...

  3. Leak detection - Wikipedia

    en.wikipedia.org/wiki/Leak_detection

    The primary purpose of leak detection systems (LDS) is to help pipeline controllers to detect and localize leaks. LDS provide alarms and display other related data to the pipeline controllers to assist decision-making. Pipeline leak detection systems can also enhance productivity and system reliability thanks to reduced downtime and inspection ...

  4. Leak noise correlator - Wikipedia

    en.wikipedia.org/wiki/Leak_noise_correlator

    A leak noise correlator is an electronic device used for Leak Detection and as a leak locator to find leaks in pressurized water or gas lines. Typically, microphones or acoustic sound sensors are placed in contact with the pipe, at two or more points, to record the sound emitted by a leak (e.g. a hissing noise) somewhere between the points.

  5. Water detector - Wikipedia

    Water detector. A water detector is an electronic device that is designed to detect the presence of water for purposes such as to provide an alert in time to allow the prevention of water leakage. A common design is a small cable or device that lies flat on a floor and relies on the electrical conductivity of water to decrease the resistance ...

  7. Hydrostatic test - Wikipedia

    en.wikipedia.org/wiki/Hydrostatic_test

    A hydrostatic test is a way in which pressure vessels such as pipelines, plumbing, gas cylinders, boilers and fuel tanks can be tested for strength and leaks. The test involves filling the vessel or pipe system with a liquid, usually water, which may be dyed to aid in visual leak detection, and pressurization of the vessel to the specified test ...

  8. Grid-leak detector - Wikipedia

    en.wikipedia.org/wiki/Grid-leak_detector

    A grid leak detector is an electronic circuit that demodulates an amplitude modulated alternating current and amplifies the recovered modulating voltage. The circuit utilizes the non-linear cathode to control grid conduction characteristic and the amplification factor of a vacuum tube. [1] [2] Invented by Lee De Forest around 1912, it was used ...

  9. Tank leak detection - Wikipedia

    en.wikipedia.org/wiki/Tank_leak_detection

    Tank leak detection. Tank leak detection is implemented to alert the operator to a suspected release from any part of a storage tank system, what enables to prevent from soil contamination and loss of product. In many countries regulated UST are required to have an approved leak detection method so that leaks are discovered quickly and the ...
