Claims

[Scope of utility model registration request]

A valve hole is formed in the flow passage of the tubular main body, and an on-off valve that can open and close the valve hole of the flow passage by operating in response to an electric signal is provided in the main body. A branch passage that bypasses the hole and communicates with the downstream side is formed so as to have a smaller cross-sectional area than the flow passage, and a measuring stage capable of measuring the flow rate of the fluid flowing through each passage is provided, and from this measuring means. By applying an electric signal to the on-off valve, the valve hole is set to open when the flow rate exceeds a predetermined value, and to close when the flow rate is less than a predetermined amount. Characterized by flow rate.
