Application of correlative technology for the measurement of refrigerant flow rate in a capillary tube.

Author(s) : ZHOU Z. K., LIU C. Y., LI Q. F., ZHANG S. T.

Summary

Flow noises exist while refrigerant flows through a capillary tube, and can be measured and transformed by electric capacity sensor into two-way correlative random signals. The refrigerant flowrate can be calculated after correlative analysis based on the two-way signals. The principle of measurement, the method of the extraction of flow noises, and the electric capacity detection circuit are also discussed in the paper.
