Hello friends, do any of you have an arduino program code idea for monitoring the volume of water in a tank with a MPS20N0040D-D barometric digital sensor?
I am very grateful for your attention
Hello rahimpuji
Take a search engine of your choice and ask the WWW for 'MPS20N0040D-D +arduino' to collect some data to be sorted out to get the needed information.

@paulpaulson , I think that @rahimpuji's favorite search engine is broken

lol, reading the features on Ali....
i quote..
The specific pressure value needs to be calculated by yourself. We can't provide other information. After reading the above description, we are shooting.
So the good answer is 42..
good luck.. ~q

If your water tank height is less than 4 meters and you have pipe connection at the bottom level you can use that sensor (otherwise do it with ultrasonic distance sensor from top). You can use some example code used for HX710(/HX711), for example weight scale implementation. Rest is just conversion and calibration.
