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. 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. Turndown ratio - Wikipedia

   en.wikipedia.org/wiki/Turndown_ratio

   The examples are here for gas flow, but the same meter types can be used on liquids as well, with similar turndown ratios. Note that meter manufacturers state their products' turndown ratios—a specific product may have a turndown ratio that varies from the list below. [citation needed] A thermal mass flow meter has a turndown ratio of 1000:1.

5. Water metering - Wikipedia

   en.wikipedia.org/wiki/Water_metering

   Ultrasonic meters may either be of flow-through or "clamp-on" design. Flow-through designs are those where the water passes directly through the meter, and are typically found in residential or commercial applications. Clamp-on designs are generally used for larger diameters where the sensors are mounted to the exterior of pipes, etc ...

6. Custody transfer - Wikipedia

   en.wikipedia.org/wiki/Custody_transfer

   Custody transfer is one of the most important applications for flow measurement. Many flow measurement technologies are used for custody transfer applications; these include differential pressure (DP) flowmeters, turbine flowmeters, positive displacement flowmeters, Coriolis flowmeters and ultrasonic flowmeters.

7. Allocation (oil and gas) - Wikipedia

   en.wikipedia.org/wiki/Allocation_(oil_and_gas)

   Fiscal measurement: N/A Flow to shared facility, from a satellite field: Custody transfer measurement (when ownership changes) Field allocation Flow from the reservoir: Allocation measurement: Back allocation to well or formation Flow from a gas well: E.g. with ultrasonic flow meter: Flow from an oil well: Well test or with multiphase meter for ...

   Students can't graduate if they don't practice on real people, so they need the community to help by booking appointments for eyebrows, facials, makeup and waxing.

9. Flow conditioning - Wikipedia

   en.wikipedia.org/wiki/Flow_conditioning

   The fundamental difference between the orifice meter and the turbine meter is the flow equation derivation. The orifice meter flow calculation is based on fluid flow fundamentals (a 1st Law of Thermodynamics derivation utilizing the pipe diameter and vena contracta diameters for the continuity equation). Deviations from theoretical expectation ...
