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. Gas meter - Wikipedia

   en.wikipedia.org/wiki/Gas_meter

   The meter then compares the difference between the upstream and downstream speeds to calculate the velocity of gas flow. Ultrasonic meters are high-cost and work best with no liquids present at all in the measured gas, so they are primarily used in high-flow, high-pressure applications such as utility pipeline meter stations, where the gas is ...

4. Custody transfer - Wikipedia

   en.wikipedia.org/wiki/Custody_transfer

   Custody transfer measurements have been around for a long time, and over the past ten years, Coriolis and ultrasonic meters have become the flowmeters of choice for custody transfer in the oil and gas industry. Ultrasonic meters provide volumetric flow rate.

5. 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.

6. 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.
