The main technical means for achieving the foregoing objective is that the water leakage detecting water meter comprises: a water meter body having an input end and an output end, wherein the water meter body is configured to flow between the input end and the output end. Water consumption value; a detecting water flow device, which is disposed outside the water meter body, the detecting water flow device includes a setting unit, a control module and a buzzer, and the control module is respectively connected with the setting unit and the buzzer Connecting, and controlling the module to be connected with the water meter body to obtain a water consumption value, the setting unit is configured to set one or more detection section times of the control module, one or more triggering times and one or more leakage water limit values, the triggering The time is less than the detection period time, and the control module compares the water consumption value and the leakage water limit value according to the set trigger time in the set detection period time, and exceeds the set time in any trigger time. The leaking water limit is an alarm from the buzzer.

The water leakage detecting water meter composed of the foregoing components is used to set the detection section time of the control module through the setting unit during the night or when the water is not used, and the control module continuously obtains in the detection period time according to the set trigger time. The water consumption value flowing through the water meter body is compared with the set leakage water limit value, and the control module determines that the leaking water limit value exceeds the set water leakage limit, indicating that a water leakage has occurred, and the buzzer immediately issues an alarm to remind the pipeline of water leakage, and solve the existing problem. Users can't find water leaks in time, causing the loss of money and water resources.

A preferred embodiment of the present invention, as shown in FIGS. 1 and 2, includes a water meter body 10 and a detecting water flow device 20 disposed outside the water meter body 10. The detecting water flow device 20 is connected to the transmission line. Water meter body 10, wherein

The amount of water used between 11 and output 12.

The detecting water flow device 20 is disposed outside the water meter body 10 . As shown in FIG. 2 , the detecting water flow device 20 includes a setting unit 21 , a control module 22 , a buzzer 23 and a display unit 24 . The control module 22 is electrically connected to the setting unit 21, the buzzer 23 and the display unit 24, respectively, and the control module 22 is connected to the water meter body 10 to obtain the value of the water consumption amount and is displayed by the display unit 24, the setting unit 21 is used to set one or more detection section times of the control module 22, and one or more leaks The upper limit value and the plurality of trigger times, the trigger time is less than the detection period time, the control module 22 obtains the water consumption value of the time period in each trigger time, and the control module 22 is in the selected detection section. The water consumption and the leakage water limit are compared according to the trigger time of each period, and the alarm is issued by the buzzer 23 or the display unit 24 when the leakage limit is set. In this embodiment, the detection period time is For a user-settable time value or a time value that can be selected by the control module 22, such as: 1 hour, 2 hours, 4 hours or 8 hours, the leakage limit is one. The self-selected water quantity value, such as: 0.1 liter, 0.5 liter, 1 liter, the trigger time is a user-settable time value or a time value that can be selected by the control module 22, such as: In the minute, 10 minutes or 30 minutes, since the trigger time is less than the detection period time, the control module 22 can perform multiple trigger times in the detection period time, and each trigger time is used to obtain the water consumption value of the period. And then with the selected leak The upper limit value is compared.
