  2. Backflow prevention device - Wikipedia

    en.wikipedia.org/wiki/Backflow_prevention_device

    Backflow prevention device. The simplest, most reliable way to provide backflow prevention is to provide an air gap.An air gap is simply an open vertical space between any device that connects to a plumbing system (like a valve or faucet) and any place where contaminated water can collect or pool.

  3. Water detector - Wikipedia

    en.wikipedia.org/wiki/Water_detector

    A water detector is an electronic device that is designed to detect the presence of water for purposes such as to provide an alert in time to allow the prevention of water leakage. A common design is a small cable or device that lies flat on a floor and relies on the electrical conductivity of water to decrease the resistance across two contacts.

  4. Instrumentation in petrochemical industries - Wikipedia

    en.wikipedia.org/wiki/Instrumentation_in...

    Instrumentation comprises sensor elements, signal transmitters, controllers, indicators and alarms, actuated valves, logic circuits and operator interfaces. An outline of key instrumentation is shown on Process Flow Diagrams (PFD) which indicate the principal equipment and the flow of fluids in the plant.

  5. Vortex flowmeter - Wikipedia

    en.wikipedia.org/wiki/Vortex_flowmeter

    A vortex flowmeter has the following components: A flow sensor operable to sense pressure variations due to vortex-shedding of a fluid in a passage and to convert the pressure variations to a flow sensor signal, in the form of an electrical signal; and a signal processor operable to receive the flow sensor signal and to generate an output signal corresponding to the pressure variations due to ...

  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. Magnetic flow meter - Wikipedia

    en.wikipedia.org/wiki/Magnetic_flow_meter

    The magnetic flow meter requires a conducting fluid, for example, water that contains ions, and an electrical insulating pipe surface, for example, a rubber-lined steel tube. If the magnetic field direction were constant, electrochemical and other effects at the electrodes would make the potential difference difficult to distinguish from the ...

  8. Water metering - Wikipedia

    en.wikipedia.org/wiki/Water_metering

    A typical residential water meter. Water metering is the practice of measuring water use.Water meters measure the volume of water used by residential and commercial building units that are supplied with water by a public water supply system.

  9. Mass flow controller - Wikipedia

    en.wikipedia.org/wiki/Mass_flow_controller

    All mass flow controllers have an inlet port, an outlet port, a mass flow sensor and a proportional control valve. The MFC is fitted with a closed loop control system which is given an input signal by the operator (or an external circuit/computer) that it compares to the value from the mass flow sensor and adjusts the proportional valve ...
