  2. Microwave power meter - Wikipedia

    en.wikipedia.org/wiki/Microwave_power_meter

    A microwave power meter is an instrument which measures the electrical power at microwave frequencies typically in the range 100 MHz to 40 GHz.. Usually a microwave power meter will consist of a measuring head which contains the actual power sensing element, connected via a cable to the meter proper, which displays the power reading.

  3. Water flow test - Wikipedia

    en.wikipedia.org/wiki/Water_flow_test

    A process to perform a water flow test is explained in the model fire codes as published by NFPA (National Fire Protection Association). If a water supply source is considered weak compared to what is required by the sprinkler system design hydraulic calculation , the water pressure can be boosted by means of a fire pump .

  4. Microwave radiometer - Wikipedia

    en.wikipedia.org/wiki/Microwave_radiometer

    A microwave radiometer (MWR) is a radiometer that measures energy emitted at one millimeter-to-metre wavelengths (frequencies of 0.3–300 GHz) known as microwaves. Microwave radiometers are very sensitive receivers designed to measure thermally-emitted electromagnetic radiation. They are usually equipped with multiple receiving channels to ...

  5. Watercut meter - Wikipedia

    en.wikipedia.org/wiki/Watercut_meter

    The main technologies are dielectric measurements using radio or microwave frequency and NIR measurements and less common are gamma ray based instruments. The water cut is the ratio of water produced compared to the volume of total liquids produced from an oil well. The water cut in waterdrive reservoirs can reach very high values. [2]

  6. Smart meter - Wikipedia

    en.wikipedia.org/wiki/Smart_meter

    The term smart meter often refers to an electricity meter, but it also may mean a device measuring natural gas, water or district heating consumption. [1] [2] More generally, a smart meter is an electronic device that records information such as consumption of electric energy, voltage levels, current, and power factor.

  7. Flow measurement - Wikipedia

    en.wikipedia.org/wiki/Flow_measurement

    Turbine meters are less accurate than displacement and jet meters at low flow rates, but the measuring element does not occupy or severely restrict the entire path of flow. The flow direction is generally straight through the meter, allowing for higher flow rates and less pressure loss than displacement-type meters.

  9. Microwave engineering - Wikipedia

    en.wikipedia.org/wiki/Microwave_Engineering

    The microwave engineering discipline has become relevant as the microwave domain moves into the commercial sector, and no longer only applicable to 20th and 21st century military technologies. Inexpensive components and digital communications in the microwave domain have opened up areas pertinent to this discipline.
