2. Ultrasonic flow meter - Wikipedia

   en.wikipedia.org/wiki/Ultrasonic_flow_meter

   Schematic view of a flow sensor. 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 propagating into and ...

3. Custody transfer - Wikipedia

   en.wikipedia.org/wiki/Custody_transfer

   Ultrasonic flow meters have negligible pressure drop if recommended installation is followed, have high turndown capability, and can handle a wide range of applications. Crude oil production, transportation, and processing are typical applications for this technology.

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. Flow conditioning - Wikipedia

   en.wikipedia.org/wiki/Flow_conditioning

   In case of a perfect fully developed real velocity profile of Ultrasonic meter which is shown in Fig.(7) indicating a possible sound path as a result of an installation in a real flow. Figure (7) showing Ultrasonic meter sound path - fully developed flow. Here a mathematical derivation for this Ultrasonic meter is also becomes very complicated.

6. Gas meter - Wikipedia

   en.wikipedia.org/wiki/Gas_meter

   A gas meter is a specialized flow meter, used to measure the volume of fuel gases such as natural gas and liquefied petroleum gas. Gas meters are used at residential, commercial, and industrial buildings that consume fuel gas supplied by a gas utility .

7. Multiphase flow meter - Wikipedia

   en.wikipedia.org/wiki/Multiphase_flow_meter

   Most modern meters combine a venturi flow rate meter, with a gamma densitometer, and some meters have additional measurements for water salinity. The meter measures the flow rates at line pressures, which are typically orders of magnitude greater than atmospheric pressure, but the meter must report the oil and gas volumes at standard ...
