Particle Image Velocimetry (PIV) is a laser optical technique for the fast and non-intrusive measurement of whole flow fields. The technique is applicable to a whole range of liquid and gaseous flows, from microscopic channels to external aerodynamics of cars and airplanes. Velocities can be measured from mm/s to supersonic.

Laser Doppler Velocimetry （激光多普勒测速）

Laser Doppler Velocimetry (LDV) is a non-intrusive point measurement technique for measuring flow velocities and turbulence. LDV is highly accurate (up to 0.1%),has a large dynamic range and a high spatial and temporal resolution. ILA offer a wide range of modular LDV systems from 1D to 3D. The technique has countless applications in industry and research, including aerospace, turbomachinery and process engineering to name but a few

传感器校正

Flow sensors such as cup or vane anemometers need to be calibrated if they are to provide accurate readings. Because it provides a direct measurement of flow velocity, LDV is highly suitable as a primary standard for flow sensor calibration. ILA offer a range of LDV calibration probes that are optimised for industrial use
