Particle Image Velocimetry (PIV) Principle
Particle image velocimetry (PIV) is an optical method of flow visualization used to obtain instantaneous velocity measurements and related properties in fluids.
Flow Measurement: Learn about Flow Sensors like Orifice, Venturi, Annubar, Pitot, Magnetic, Turbine, Ultrasonic, Coriolis flow meters, etc.

A recent development in industrial flow measurement is Optical Flow Meter which uses light to measure the velocity of a fluid through a pipe.
Ultrasonic flow meter measures fluid velocity by passing high-frequency sound waves along the fluid flow path.
Positive Displacement Flow Meter are rotary in nature, meaning each shaft revolution represents a certain volume of fluid has passed through meter.
Most common weigh feeder design consists of a conveyor belt with a section supported by rollers coupled to one or more load cells.
Magnetic Flow Meter based on electromagnetic induction. These flow meters are commonly known as magnetic flowmeters or simply magflow meters.
A variation of turbine flow measurement is the paddle wheel flow meter, a very inexpensive technology usually in the form of an insertion-type flow sensor.
Turbine flow meter use a free-spinning turbine wheel to measure fluid velocity, much like a miniature windmill installed in the flow stream.
Vortex Flow Meter based on phenomenon is known as vortex shedding. When fluid moves in a pipe then vortices will form when flow hit the bluff body.
Velocity-based Flow Meter able to directly measure fluid velocity, therefore capable of inferring volumetric flow rate of fluid in a pipe.
