Ultrasound also work well with non-conduction fluids like fuel and other hydrocarbons. A sensor for this project should be easy to connect to the Raspberry interface, analog, I2C, On/off or other simple interface. It should also be cost effective.
I found it from Aliexpress also : https://www.aliexpress.com/item/Ultrasonic-Module-Distance-Measuring-Transducer-Sensor-Waterproof-DC-5V/32330248071.html
