Which water level sensor for a 5000l tank with integration with Supla - precise reading?

Hello, I have several devices connected under suple, also I have a 5000 l rainwater tank. I would like to set up some kind of sensible water level sensor in the tank. However, I am keen for one that shows if there is, for example, half of the tank or that it is 3/4 full. do you have any ideas about this? Greetings
AI: Can you please write exactly what kind of tank you have (e.g. is it buried, what material, do you have easy access from the top to mount the sensor)? .
Bolt 5000 l plastic tank
AI: Do you have a preference for the type of sensor (e.g. ultrasonic, pressure, float) or restrictions on budget, power supply or method of connection (wired/wireless)?
I am looking for a WiFi wireless sensor, works on the tank site. I have no preference. I am looking for some sort of budget version.

Can it be easily connected to the Supla app?
