警報を発する。Embodiments of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, 1 is a primary side water supply pipe, 2 is 2
The secondary side water pipe 3 is a flow rate measuring means for measuring the amount of water flowing through the pipe, and converts a rotating body such as an impeller rotating according to the flow rate into an electric pulse signal by a magnetoelectric conversion element. 4 and 5
Are faucets respectively connected to the home, and 6 is a flow rate measuring means 3
It is a flow rate alarming means that determines the flow rate to be used from the flow rate pulse from and issues an alarm. The flow rate alarming means 6 is set by an instantaneous flow rate measuring means 7 for measuring the flow rate pulse from the flow rate measuring means 3 as an instantaneous flow rate value, a minimum flow rate setting means 8 for setting a minimum flow rate value of the measured flow rate, and a minimum flow rate setting means 8. The minimum flow rate value and the lower limit flow rate of the flow rate measuring means 3 are detected, and an alarm signal is output when the flow rate has passed a predetermined time. And the notification unit 10 for The instantaneous flow rate measuring means 7 obtains the flow rate pulse from the flow rate measuring means 3 as an instantaneous flow rate value from the number per unit time. The duration determination unit 9 is composed of a determination unit 11 for comparing and determining the flow rate value set by the minimum flow rate setting unit 8 and the flow rate value measured by the instantaneous flow rate measurement unit 7, and a timer unit 12 for duration measurement. It The determination unit 11 activates the timer unit 12 when the flow rate value measured by the instantaneous flow rate measurement unit 7 reaches the flow rate value set by the minimum flow rate setting unit 8 or less, and starts the time measurement of the flow rate state. Then, when the time set in the timer unit 12 is reached, an alarm signal is sent to the notification unit 10. The notification unit 10 displays an alarm sound or an alarm mark. The minimum flow rate setting means 8 sets a practical flow rate value that a person uses by opening the faucet. For example, if the amount used as cooling water for cooking is 0.5 liter / minute, The flow rate value below the value is not in the state where the consumer intentionally uses it. Therefore, if the flow rate value in the above-mentioned flow rate range continues, it is determined that the water leak has failed due to incomplete closure of the faucet or aging of the faucet, and an alarm is issued.

示すように、最小流量設定値区分に応じて定めている。The operation of the above configuration will be described with reference to FIG. 2 and (Table 1). In FIG. 2, the horizontal axis represents time, and the vertical axis represents the flow rate value measured by the instantaneous flow rate measuring means 7. In the figure, the flow rate value from time t0 to ts increases and decreases at certain time intervals depending on the action of the user. From time ts, the region flow rate that is equal to or less than the minimum flow rate setting value and equal to or more than the measurement lower limit flow rate value of the flow rate measuring means 3 continues. When the determination unit 11 detects the flow rate, the duration determination unit 9 activates the timer unit 12, but does not reach the time of issuing an alarm. When the above flow rate state continues from time ts to tn, the duration determination unit 9 sends an alarm signal to the notification unit 10 to warn. The alarm output determination time of the timer unit 12 is determined according to the minimum flow rate setting value category, as shown in (Table 1).

逸脱すると解除する。The alarm output determination time shown in Table 1 is an example for general households because the lower limit flow rate of the flow rate measuring means 3 varies depending on the water supply contract diameter. The practical flow rate range is 15 liters per minute or more for pouring into bathtubs and 6 liters per minute for dishwashing in the kitchen. The alarm is released when the flow rate value deviates from the minimum flow rate setting value and the lower limit value of the measurement value by the faucet operation.

Further, the flow rate value set by the minimum flow rate setting means 8 can be learned by learning the usage pattern of the consumer, and the setting can be automatically updated to configure a monitoring device adapted to a practical level.
