Transceiver integrated 16mm 40KHz Ultrasonic Sensor(waterproof type) Ultrasonic

I'm a newbie to both the arduino and the electronic world in general. I hope I can describe my inquiry in good enough detail for you to help me.

I took a you tube lesson on using the ultrasonic sensors to measure distances and also ran across an article where they were using ultrasonic transducers to measure wind speed taking in consideration the doppler effect. I have found some waterproof sensors (ie my subject line) but the documentation is lacking at least for a newbie like me.

Does anyone know if this type of project has been done before with an Arduino? Is there any documentation of a similar project that a person like me could follow?

Looking through the past forums, I know that there are always individuals ready to help. To those, I send you a thank you in advance.
