LASER DOPPLER VELOCIMETER

A Laser Doppler Velocimeter (LDV) is an advanced instrument used to measure the velocity of particles in a fluid flow. It operates on the principle of the Doppler effect, where the frequency of light scattered by particles moving in the fluid is shifted relative to the source. The LDV directs a laser beam at the fluid, and when particles reflect th

An ultrasonic flow meter is a highly accurate device used to measure the flow rate of liquids or gases in pipelines. It works by emitting high-frequency sound waves into the fluid and measuring the time it takes for the waves to travel through the medium. There are two main types: transit-time and Doppler. Transit-time meters calculate the differen
