Claims (1)
流量を測定する羽根車式流量センサーであつて、
羽根車１の羽根１ａをその回転軸２の軸線に対し
て傾斜させたものにおいて、該羽根車１の出口側
に液体等の逆流による羽根車１の逆回転を防止す
る斜流部３を設けたことを特徴とする流量センサ
ー。 羽根車１の羽根１ａを入口側の斜状案内羽根
４による旋回流を受けやすい方向に傾斜させ、か
つ、斜流部３を該羽根車１の羽根１ａと同方向に
傾斜させた請求項１記載の流量センサー。[Scope of Claim for Utility Model Registration] An impeller-type flow rate sensor that measures the flow rate by counting pulses generated by the rotation of the impeller 1,
In the case where the blades 1a of the impeller 1 are inclined with respect to the axis of the rotation shaft 2, a diagonal flow section 3 is provided on the outlet side of the impeller 1 to prevent reverse rotation of the impeller 1 due to backflow of liquid etc. A flow rate sensor characterized by: Claim 1, wherein the blades 1a of the impeller 1 are inclined in a direction in which the swirling flow is easily received by the oblique guide vanes 4 on the inlet side, and the diagonal flow section 3 is sloped in the same direction as the blades 1a of the impeller 1. Flow sensor listed.
