Ultrasonic sensor configuration (DYP-ME007TX)

Hi, I want to ignore the tenk surface and mesure the distance between the sensor and the water surface. Is it possible to configure the "DYP-ME007TX" to get a such result? Description scheme : https://ibb.co/h6XEfy

If the tanks is closed, probably not. But in case of doubt, post a diagram clearly showing the relationship between the tank, the water and the sensor.

Most forum members won't follow a mysterious link.
