  2. Mass flow meter - Wikipedia

    en.wikipedia.org/wiki/Mass_flow_meter

    The mass flow of a U-shaped Coriolis flow meter is given as: Q m = K u − I u ω 2 2 K d 2 τ {\displaystyle Q_{m}={\frac {K_{u}-I_{u}\omega ^{2}}{2Kd^{2}}}\tau } where K u is the temperature dependent stiffness of the tube, K is a shape-dependent factor, d is the width, τ is the time lag, ω is the vibration frequency, and I u is the inertia ...

    en.wikipedia.org/wiki/Custody_transfer

    Coriolis technology offers accuracy and reliability in measuring material flow, and is often hailed as among the best flow measurement technologies due to direct mass flow, fluid density, temperature, and precise calculated volume flow rates. Coriolis meters do not have any moving parts and provide long term stability, repeatability, and ...

  4. Flow measurement - Wikipedia

    en.wikipedia.org/wiki/Flow_measurement

    Ultrasonic flow meter; Mass flow meter (Coriolis force). Flow measurement methods other than positive-displacement flowmeters rely on forces produced by the flowing stream as it overcomes a known constriction, to indirectly calculate flow. Flow may be measured by measuring the velocity of fluid over a known area.

  5. Water metering - Wikipedia

    en.wikipedia.org/wiki/Water_metering

    A Coriolis water meter is a precision instrument used to measure the mass flow rate and density of fluids, including water, by utilizing the Coriolis effect. Unlike traditional mechanical meters with moving parts, Coriolis meters use oscillating tubes through which the fluid flows.

  6. Coriolis force - Wikipedia

    en.wikipedia.org/wiki/Coriolis_force

    A practical application of the Coriolis effect is the mass flow meter, an instrument that measures the mass flow rate and density of a fluid flowing through a tube. The operating principle involves inducing a vibration of the tube through which the fluid passes.

  7. Gas meter - Wikipedia

    en.wikipedia.org/wiki/Gas_meter

    Orifice meters are a type of differential meter, all of which infer the rate of gas flow by measuring the pressure difference across a deliberately designed and installed flow disturbance. The gas static pressure, density, viscosity, and temperature must be measured or known in addition to the differential pressure for the meter to accurately ...
