It's the measure of flow.
Laser Doppler velocimetry is a non-intrusive technique used to measure flow velocity by analyzing the Doppler shift of laser light scattered by moving particles. It is commonly used in fluid mechanics research to measure fluid flow velocities in a wide range of applications, such as aerodynamics, biofluid dynamics, and industrial flows. The technique provides high spatial resolution and can be used to map velocity fields in complex flow configurations.

The ultrasonic documentation that records velocity mapping and imaging is known as Doppler ultrasound. It uses the Doppler effect to measure the speed and direction of blood flow in the body's blood vessels.
An ultrasonic Doppler device is commonly used for recording velocity mapping and imaging. This device works by emitting ultrasonic waves that bounce off moving blood cells and produce velocity measurements based on the Doppler effect. These measurements can then be used to create images showing the velocity and direction of blood flow in vessels or organs.

One example of ultrasonic documentation that records velocity mapping and imaging is a Doppler ultrasound report. This report uses the Doppler effect to assess blood flow velocity and direction in vessels or organs. It provides detailed information on blood flow patterns and can be used to diagnose conditions such as deep vein thrombosis or heart valve malfunctions.

Both the doppler and transit time ultrasonic fllow meter have a cost that is relatively high in comparison with other types of pipe flow meter. ultrasonic flow meter are not recommended for primary sludge , mixed liquor,carbon sludge
Ultrasonic imaging is the technique of non-invasive examination of the heart and arteries.With refinements of Doppler imaging, the velocity of the blood may be indicated, and the presence of constrictions shown.
