Water Sensor Leak alert with sensor running over 10 minutes without stopping?


i have a Water Sensor, which gives me a number of water consumption in liters.

I just have one sensor.wasserverbrauch with the liters but now, i want to send a notification to my phone, when the sensor.wasserverbrauch is running over 10 minutes.

Is there any possible way with automation or helper or so?
I want to find leaks, if there is some. Normally, we dont run shower over 10minutes or so. But if this sensor is running over 10 minutes in a row, i will have notification.

Any ideas how to check that, if the sensor never stopped over 10 minutes?
