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. Ultrasonic transducer - Wikipedia

   en.wikipedia.org/wiki/Ultrasonic_transducer

   A curvilinear array ultrasonic transducer for use in medical ultrasonography Inside construction of a Philips C5-2 128 element curved array ultrasound sensor. Ultrasonic transducers and ultrasonic sensors are devices that generate or sense ultrasound energy. They can be divided into three broad categories: transmitters, receivers and transceivers.

4. Flow measurement - Wikipedia

   en.wikipedia.org/wiki/Flow_measurement

   Schematic view of a flow sensor. Ultrasonic transit time flowmeters measure the difference of the transit time of ultrasonic pulses propagating in and against the direction of flow. This time difference is a measure for the average velocity of the fluid along the path of the ultrasonic beam.

5. Ultrasound - Wikipedia

   en.wikipedia.org/wiki/Ultrasound

   Ultrasonic sensors are also used to detect intruders; the ultrasound can cover a wide area from a single point. The flow in pipes or open channels can be measured by ultrasonic flowmeters, which measure the average velocity of flowing liquid. In rheology, an acoustic rheometer relies on the principle of ultrasound.

7. Level sensor - Wikipedia

   en.wikipedia.org/wiki/Level_sensor

   Ultrasonic level sensor used in a water treatment plant. Ultrasonic level sensors are used for non-contact level sensing of highly viscous liquids, as well as bulk solids. They are also widely used in water treatment applications for pump control and open channel flow measurement.
