  2. Tank leak detection - Wikipedia

    en.wikipedia.org/wiki/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 release is stopped in time.

  3. Level sensor - Wikipedia

    en.wikipedia.org/wiki/Level_sensor

    A variation of magnetic sensing is the "Hall effect" sensor which utilizes the magnetic sensing of a mechanical gauge's indications. In a typical application, a magnetism-sensitive "Hall effect sensor" is affixed to a mechanical tank gauge that has a magnetized indicator needle, so as to detect the indicating position of the gauge's needle.

    The digital fuel gauge in a 2018 Mazda 3 showing a nearly-empty tank along with a distance to empty display. Typical old-style fuel gauge on a 50 ccm chinese-made scooter from 2008, with the internationally used pictogram of a gas pump. The system can be fail-safe. If an electrical fault opens, the electrical circuit causes the indicator to ...

    en.wikipedia.org/wiki/Oil_tanker

    Tank-gauging equipment is used to tell the person in charge how much space is left in the tank, and all tankers have at least two independent methods for tank-gauging. [101] As the tanker becomes full, crew members open and close valves to direct the flow of product and maintain close communication with the pumping facility to decrease and ...

    en.wikipedia.org/wiki/Custody_transfer

    Custody transfer measurements involve measurements in pipelines, storage tanks, transportation tanks (tankers, trailers or railway tanks) - whole fuel distribution process must be traceable. In order measurements can be made in a volume or mass units (or both), so various metering methods are commonly used. [3]

    en.wikipedia.org/wiki/Tank_locomotive

    LB&SCR J1 class. A tank locomotive is a steam locomotive which carries its water in one or more on-board water tanks, instead of a more traditional tender.Most tank engines also have bunkers (or fuel tanks) to hold fuel; in a tender-tank locomotive a tender holds some or all of the fuel, and may hold some water also.

  8. Magnetic level gauge - Wikipedia

    en.wikipedia.org/wiki/Magnetic_level_gauge

    A magnetic level gauge pulled out from inside the valve housing on top of a railway tank car in the United States [1]. A magnetic level gauge is a level gauge based on a float device that can experience floatation in both high and low density fluids.

  9. Sight glass - Wikipedia

    en.wikipedia.org/wiki/Sight_glass

    Water gauge on a steam locomotive. Here the water is at the “top nut”, the maximum working level. Note the patterned backplate to help reading and toughened glass shroud. A sight glass or water gauge is a type of level sensor, a transparent tube through which the operator of a tank or boiler can observe the level of liquid contained within.
