  2. Ultrasonic flow meter - Wikipedia

    en.wikipedia.org/wiki/Ultrasonic_flow_meter

    An ultrasonic flow meter is a type of flow meter that measures the velocity of a fluid with ultrasound to calculate volume flow. Using ultrasonic transducers, the flow meter can measure the average velocity along the path of an emitted beam of ultrasound, by averaging the difference in measured transit time between the pulses of ultrasound ...

  3. 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.

  4. Water metering - Wikipedia

    en.wikipedia.org/wiki/Water_metering

    Ultrasonic water meters are highly accurate devices, with residential models capable of measuring flow rates as low as 1 liter per hour (L/h). [2] They feature wide flow measurement ranges, require minimal maintenance, and have long lifespans due to the absence of internal mechanical components that could wear out over time. [3]

  5. Custody transfer - Wikipedia

    en.wikipedia.org/wiki/Custody_transfer

    Because they are direct mass flow measurement devices, Coriolis meters can handle the widest range of fluids from gases to heavy liquids and are not impacted by viscosity or density changes that often effect velocity based technologies (PD, Turbine, Ultrasonic).

    en.wikipedia.org/wiki/Brooks_Instrument

    Brooks Instrument is a manufacturer of flow control and measurement equipment based in Hatfield, PA.It was a division of Emerson (NYSE:EMR) until December 31, 2007 when it was sold to American Industrial Partners Capital Fund IV (“AIP”) for approximately $100 million in cash.

  7. Flow conditioning - Wikipedia

    en.wikipedia.org/wiki/Flow_conditioning

    Figure (5) showing ultrasonic meter sound path - no flow. Due to the relative age of the technology, it may be beneficial to discuss the operation of the multipath ultrasonic meter to illustrate the effects of flow profile distortion and swirl. There are various types of flow measurements utilizing high frequency sound.
