Tank Level from Hydrostatic Pressure Sensor?

[myocean]

Due to some unknown reason our boat has no water tank">fresh water tank level sensor and the installation of a rigid capacitive probe from the top of the tank is nearly impossible because the fuel tank is stacked on top of it.
So I consider using a hydrostatic pressure sensor which I can just "throw in" and let measure on the ground of the tank.
Such sensors usually come with a 4-20 mA output and are quite expensive.

Are there any hints or recommendations?

The tank tender system will fit when most others won't. It's also probably the best.

Is it really necessarily to view the tank level from your console?
I just put 2 connections on my tank one on the bottom one on the top and a nice clear pipe in between to indicate the tank level. Cheap and never fails.

Be careful, don't put the bottom connection to close to the pump suction or it will drag in air trough the sounding pipe.
