SMART LDV IIIRequest Quote
Simple and easy operated LDV (Laser Doppler Velocimeter) for accurate flow velocity measurement with high repeatability.
A Laser Doppler Velocimeter (LDV) measures fluid velocity by utilizing coherence of laser light. It detects the Doppler shift frequency of the scattering light of particles in the fluid and calculates the velocity of the particles (fluid). With a LDV system, non-intrusive measurements without disturbing the measuring object, liquid or gas flow, are achieved. No calibration is necessary and reverse flow measurements at a high resolution is also possible. The LDV system provides the absolute value of the flow velocity with accuracy.
The Smart LDV Ⅲ is a high quality Laser Doppler Velocimeter and compact in design. Absolute velocity measurement with high repeatability is realized with the Smart LDV Ⅲ.
