  2. 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 ...

  3. Tracer-gas leak testing - Wikipedia

    en.wikipedia.org/wiki/Tracer-gas_leak_testing

    A tracer-gas leak testing method is a nondestructive testing method that detects gas leaks.A variety of methods with different sensitivities exist. Tracer-gas leak testing is used in the petrochemical industry, the automotive industry, the construction industry [1] and in the manufacture of semiconductors, among other uses.

  4. Gas detector - Wikipedia

    en.wikipedia.org/wiki/Gas_detector

    Gas leak detection is the process of identifying potentially hazardous gas leaks by sensors. Additionally a visual identification can be done using a thermal camera These sensors usually employ an audible alarm to alert people when a dangerous gas has been detected.

  5. 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.

  7. Electrochemical gas sensor - Wikipedia

    en.wikipedia.org/wiki/Electrochemical_gas_sensor

    The magnitude of the current is controlled by how much of the target gas is oxidized at the working electrode. Sensors are usually designed so that the gas supply is limited by diffusion, and thus the output from the sensor is linearly proportional to the gas concentration. This linear output is one of the advantages of electrochemical sensors ...
