  2. Leak detection - Wikipedia

    en.wikipedia.org/wiki/Leak_detection

    A leak appearing within an analytic region (a rule added to the camera) is immediately analyzed for its attributes, including thermal temperature, size, and behaviour (e.g. spraying, pooling, spilling). When a leak is determined to be valid based on set parameters, an alarm notification with leak video is generated and sent to a monitoring station.

  3. Heat trap - Wikipedia

    en.wikipedia.org/wiki/Heat_trap

    Heat traps are valves or loops of pipe on the cold water inlet and hot water outlet of water heaters. The heat traps allow cold water to flow into the water heater tank, but prevent unwanted natural convection and heated water to flow out of the tank. [1] [2] Newer water heaters have built-in heat traps.

  4. Microwave radiometer - Wikipedia

    en.wikipedia.org/wiki/Microwave_radiometer

    Solids, liquids (e.g. the Earth's surface, ocean, sea ice, snow, vegetation) but also gases emit and absorb microwave radiation. Traditionally, the amount of radiation a microwave radiometer receives is expressed as the equivalent blackbody temperature also called brightness temperature. In the microwave range several atmospheric gases exhibit ...

  5. Airborne particulate radioactivity monitoring - Wikipedia

    en.wikipedia.org/wiki/Airborne_particulate...

    CPAMs use a pump to draw air through a filter medium to collect airborne particulate matter that carries very small particles of radioactive material; the air itself is not radioactive. [1] The particulate radioactive material might be natural, e.g., radon decay products ("progeny", e.g., 212 Pb), or manmade, usually fission or activation ...

  6. Soil thermal properties - Wikipedia

    en.wikipedia.org/wiki/Soil_thermal_properties

    A thermal sensor can detect variations to heat transfers into and out of near surface layers because of external heating by the thermal processes of conduction, convection, and radiation. Microwave remote sensing from satellites has also proven useful as it has an advantage over TIR of not being effected by cloud cover.

  7. Electromagnetic absorption by water - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_absorption...

    Liquid water and ice emit radiation at a higher rate than water vapour (see graph above). Water at the top of the troposphere, particularly in liquid and solid states, cools as it emits net photons to space. Neighboring gas molecules other than water (e.g. nitrogen) are cooled by passing their heat kinetically to the water.
