Abstract: A venturi flowmeter includes a ring of which the inside is hollow and which prevents inner wall abrasion or fatigue load accumulation at a main orifice and thus can reduce maintenance costs. The venturi flowmeter includes a main orifice of which the inside is hollow and an element of which one side has a hollow inside having the same diameter as that of a through-hole of the main orifice, and which has a tapered shape toward the other side thereof. A diffuser has one side having a hollow inside of the same diameter as that of the through-hole of the main orifice, and which has a tapered shape toward the other side thereof. A ring is connected between the main orifice and one side of the element. The ring includes a stopper formed along an inner wall and having a hollow central portion.

Abstract: 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.
Abstract translation: 根据本发明的平均皮托管式流量计具有总压力管和静压管。 总压力管和静压管彼此间隔开。 在整个压力管和静压管之间，整流装置和连接壳体被整合成一体。 整流装置位于总压力孔之前，总压力孔和静压孔位于连接箱的内部。
