2. Float switch - Wikipedia

   en.wikipedia.org/wiki/Float_switch

   A float switch is a type of level sensor, a device used to detect the level of liquid within a tank. The switch may be used to control a pump, as an indicator, an alarm, or to control other devices. One type of float switch uses a mercury switch inside a hinged float.

3. Water level (device) - Wikipedia

   en.wikipedia.org/wiki/Water_level_(device)

   The water level at each end of the tube will be at the same elevation, whether the two ends are adjacent or far apart, so a line between them will be horizontal at its midpoint and a shed base, building foundation or similar structure laid out using several such lines will be "horizontal" within building tolerances on any scale over which use ...

4. Level sensor - Wikipedia

   en.wikipedia.org/wiki/Level_sensor

   Hydrostatic pressure level sensors are submersible or externally mounted pressure sensors suitable for measuring the level of corrosive liquids in deep tanks or water in reservoirs. Typically, fluid level is determined by the pressure at the bottom of the fluid containment (tank or reservoir); the pressure at the bottom, adjusted for the ...

5. Float (liquid level) - Wikipedia

   en.wikipedia.org/wiki/Float_(liquid_level)

   Liquid level floats, also known as float balls, are spherical, cylindrical, oblong or similarly shaped objects, made from either rigid or flexible material, that are buoyant in water and other liquids. They are non-electrical hardware frequently used as visual sight-indicators for surface demarcation and level measurement. They may also be ...

6. Flow measurement - Wikipedia

   en.wikipedia.org/wiki/Flow_measurement

   This depth is converted to a flow rate according to a theoretical formula of the form = where is the flow rate, is a constant, is the water level, and is an exponent which varies with the device used; or it is converted according to empirically derived level/flow data points (a "flow curve"). The flow rate can then be integrated over time into ...

7. 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.

8. Centimetre or millimetre of water - Wikipedia

   en.wikipedia.org/wiki/Centimetre_or_millimetre...

   A centimetre of water [1] is a unit of pressure. It may be defined as the pressure exerted by a column of water of 1 cm in height at 4 °C (temperature of maximum density) at the standard acceleration of gravity, so that 1 cmH 2 O (4°C) = 999.9720 kg/m 3 × 9.80665 m/s 2 × 1 cm = 98.063754138 Pa ≈ 98.0638 Pa, but conventionally a nominal maximum water density of 1000 kg/m 3 is used, giving ...

9. Multilevel groundwater monitoring systems - Wikipedia

   Various sensors and sampling devices could be ported through the liner where they were pressed against the borehole). Mr. Carl Keller acquired the manufacturing rights to the system in 1995 and developed a version that could be deployed below the water table for depth-discrete groundwater monitoring.
