    The difference is sent as a signal to a level control valve (LCV) on the liquid outlet from the vessel. As the level rises the controller acts to open the valve to draw off liquid to reduce the level. Similarly as the levels fall the controller acts to close the LCV to reduce outflow of fluid. [4] Some vessels store liquid until it is pumped out.

  3. Float switch - Wikipedia

    en.wikipedia.org/wiki/Float_switch

    A pedestal sump pump with a 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.

    en.wikipedia.org/wiki/Level_sensor

    Pneumatic level sensors are used where hazardous conditions exist, where there is no electric power or its use is restricted, or in applications involving heavy sludge or slurry. As the compression of a column of air against a diaphragm is used to actuate a switch, no process liquid contacts the sensor's moving parts. These sensors are suitable ...

    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.

    Internal block diagram. A mass flow controller (MFC) is a device used to measure and control the flow of liquids and gases. [1] A mass flow controller is designed and calibrated to control a specific type of liquid or gas at a particular range of flow rates.

    en.wikipedia.org/wiki/Fluid_dynamics

    In physics, physical chemistry and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids – liquids and gases.It has several subdisciplines, including aerodynamics (the study of air and other gases in motion) and hydrodynamics (the study of water and other liquids in motion).
