Thank you very much; your response is very reassuring.Well this is quite simple.
First What kind of sensor output do you have? If it is 4..20 ma you will need to add a resistor GND to signal to convert the current to voltage.
Something similar to this post.

You are using two sensors. One up and one down. Is the tank pressurized? If not you just need the bottom one.
Depending of the distance from the tank to the Pi I will suggest to use shield cable and add some RC filters to prevent noise.
I have a few 'Micro Sensor M20 pressure transmitter voltage output 10 Bar' units left over from a previous project, and I believe they could meet my current needs. Additionally, I think voltage output pressure transmitters might be a better fit for my setup compared to those with current output.
The water tank is sealed with a breather valve and is 99% at ambient pressure (around 1013 hPa), but when the irrigation system runs, the high-pressure pump momentarily causes a drop in tank pressure. The main reason for considering two pressure transmitters is that I already have a couple of them ready for installation, so using one or two doesn’t make much of a difference for me.
Thank you for your final recommendations; I will definitely keep them in mind to prevent any new issues.
