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 ...
An ultrasonic flow meter measures the velocity of a liquid or gas through a pipe using acoustic sensors. This has some advantages over other measurement techniques. The results are slightly affected by temperature, density or conductivity. Maintenance is inexpensive because there are no moving parts. Ultrasonic flow meters come in three ...
Sonar flowmeters have the capacity of measuring the velocity of liquids or gases non-intrusively within the pipe and then leverage this velocity measurement into a flow rate by using the cross-sectional area of the pipe and the line pressure and temperature. The principle behind this flow measurement is the use of underwater acoustics.

Forbidden Planet pioneered several aspects of science fiction cinema. It was the first science fiction film to depict humans traveling in a man-made faster-than-light starship. [6] It was also the first to be set entirely on a planet orbiting another star, far away from Earth and the Solar System.
All of the films include core elements of science fiction, but can cross into other genres such as drama, mystery, action, horror, fantasy, and comedy. Among the listed movies are films that have won motion-picture and science fiction awards as well as films that have been listed among the worst movies ever made , or have won one or more Golden ...
