Particle Image Velocimetry (PIV) is a widely used technology in fluid mechanics research that allows scientists to measure liquid movements with high precision. However, one of its major limitations is that it does not work well in opaque fluids. This is where Ultrasonic Velocity Profiling (UVP) technology comes in, as it is specifically designed to work in opaque liquids. In this blog post, we will explore how UVP technology can complement PIV solutions and provide accurate velocity measurements in opaque fluids.


The Limitations of PIV

PIV is a powerful technology that uses lasers to illuminate particles in a fluid and capture their movement with a high-speed camera. However, in opaque fluids, the laser light cannot penetrate through the liquid, making it impossible to track the movement of the particles. This is a significant limitation, as many industrial and biological fluids are opaque, such as oil, blood, and food products.


The Advantages of UVP

UVP technology, on the other hand, uses ultrasound to measure the velocity of particles in a fluid. This technology works well in opaque liquids, as ultrasound can penetrate through the liquid and provide accurate measurements of the particle movement. UVP technology is also non-invasive, which means that it does not alter the flow field being measured.


Met-Flow UVP-DUO

The Met-Flow UVP-DUO is a state-of-the-art UVP system that provides accurate velocity measurements in opaque fluids. It uses ultrasound to measure the velocity of particles in a fluid, providing real-time data with high spatial and temporal resolution. The UVP-DUO is a versatile system that can be used in a variety of applications, from laboratory research to industrial process control.


Another advantage of the UVP-DUO is its ease of use. The system is designed to be user-friendly, with intuitive software and a compact design that makes it easy to set up and operate. It can be used in both stationary and moving fluids, and can provide measurements in one, two and three dimensions.


In addition to its technical capabilities, the UVP-DUO is also cost-effective, providing accurate data at a fraction of the cost of other measurement techniques.
