Outline of Final Research Achievements

In this study, the development of flow rate measurement method using multi-point LDV system was performed. The multi-point LDV system construct the line-wise measurement volume whichi is applicable for high accurate flow rate measurement. After the LDV system was developed, it was applied to the pipe flow. Based on the experiments, the issues for the measurement was considered. Especially, the modification of the signal power and frequency shift was modified. Finally, the applcability of this system for the flowrate measurement was shown. Based on the results, the plane type measurement was tried as the multi-path measurement. The experimental results showed the applicability of the plane type measurement method for the flow rate measurement.
