Claims

[Scope of Claim for Utility Model Registration] A flow rate detection means for detecting a flow rate based on an electrical signal generated by the rotation of the impeller, in which a valve body and a blade wheel are provided in a flow path, and a flow rate detection means for integrating the flow rate. In an electrically controlled fixed quantity water stop faucet, which has a comparison means that outputs a valve closing signal when the amount of water stored reaches a set value, and a valve closing means that closes the valve based on the valve closing signal, a battery is used as a power source for the water stop faucet. 1. A fixed-rate stop valve of intermittent flow rate measurement type, characterized in that the flow rate detection means detects the flow rate at predetermined time intervals, and calculates the amount of water stored based on the detection operation time and the detected flow rate.
