  2. Mass flow controller - Wikipedia

    en.wikipedia.org/wiki/Mass_flow_controller

    A mass flow controller is designed and calibrated to control a specific type of liquid or gas at a particular range of flow rates. The MFC can be given a setpoint from 0 to 100% of its full scale range but is typically operated in the 10 to 90% of full scale where the best accuracy is achieved.

  3. Mass flow meter - Wikipedia

    en.wikipedia.org/wiki/Mass_flow_meter

    The mass flow rate is the mass of the fluid traveling past a fixed point per unit time. The mass flow meter does not measure the volume per unit time (e.g. cubic meters per second) passing through the device; it measures the mass per unit time (e.g. kilograms per second) flowing through the device. Volumetric flow rate is the mass flow rate ...

    FCI operates a NIST flow calibration laboratory with 19 precision flow stands. FCI utilizes these precision flow stands to flow actual gases and reference fluids matched to the temperature, process conditions, and line size of individual customers' flow meter applications. The company has subsidiaries in Tilburg, Netherlands and Beijing, China.

  5. Mass flow rate - Wikipedia

    en.wikipedia.org/wiki/Mass_flow_rate

    Mass flow rate is defined by the limit [3] [4] ˙ = =, i.e., the flow of mass m through a surface per unit time t. The overdot on the m is Newton's notation for a time derivative . Since mass is a scalar quantity, the mass flow rate (the time derivative of mass) is also a scalar quantity.

  6. Custody transfer - Wikipedia

    en.wikipedia.org/wiki/Custody_transfer

    With a fluid mass, the Coriolis force is proportional to the mass flow rate of that fluid. A Coriolis meter has two main components: an oscillating flow tube equipped with sensors and drivers, and an electronic transmitter that controls the oscillations, analyzes the results, and transmits the information.

  9. Thermal mass flow meter - Wikipedia

    en.wikipedia.org/wiki/Thermal_mass_flow_meter

    A second type is the capillary-tube type of thermal mass flow meter. Many mass flow controllers (MFC) which combine a mass flow meter, electronics and a valve are based on this design. Furthermore, a thermal mass flow meter can be built by measuring temperature differential across a silicon-based MEMS chip.
