Average pitot tube type flow meter

摘要

Average pitot-tube type flow meter according to the present invention has a total pressure tube and a static pressure tube. The total pressure tube and the static pressure tube are spaced from each other. Across the total pressure tube and the static pressure tube, a rectifying device and a connection case are installed as they are integrated into one body. The rectifying device is positioned in advance of total pressure holes and the total pressure hole and a static pressure hole are positioned inside the connection case.
