On Board Water Remote Gauge

I'm planning a rebuild of my truck bed platform, with plans for a permanently mounted water tank in the rear of my truck (behind drawers). im trying to avoid having to climb in the bed (under camper shell) everytime I want to check the water level and was wondering what sort of options every1 is using to remotely monitor the water level in OBW systems

A standard fuel gauge float works just fine. Connect it to a standard digital or analog gauge.
more specifically the logistics of that -- installing such a float in a sealed plastic tank without damaging the structural integrity and preventing leaks

Without having your exact tank right in front of me to work on, I can't give you step by step instructions, but buy something like this and follow the instructions. https://www.summitracing.com/parts/rnb-55818?seid=srese1&cm_mmc=pla-google-_-shopping-_-srese1-_-dorman&gclid=Cj0KCQjwvLLZBRDrARIsADU6ojCT3bH-_RzWLgmw3uMciGfN7RIzmzf3FjiJ2kkel79htNGABaIVmLcaAmmCEALw_wcB

Lets hope fueltank sensor is compatible with water immersion.
In industry we use a variety of sensors. Ultrasonic, laser, capacitive & so on. Most of those need threaded boss into the tank.

Is the tank wall visible and somewhat transparent ?
Now that video is crazy cheap, how about a camera ?
the tank im looking at unfortunately is not transparent

There are water tank specific senders for gauges. I don’t think I’d use a standard fuel level sender. It would rust

That's how I did mine when I had a Valterra tank:



I even measured filling from empty and added gallon-specific markers.
clever. unfortunately for my build the tank will not be anywhere with line of sight to the tank, so i would need a true remote gauge...

Look at RV parts suppliers. There are various potable water senders available. Only issue is they usually read in quarters with 4 led's instead of like a fuel gauge that's infinitely incremental.

See Level II in my RV has a strip that is put on the outside of the tank and sent to a monitor that reads in percentage.
It is pretty accurate. Also has other tank monitors, like for black and grey tank as well.

that option is very neat! i like that you don't need to drill the tank at all -- downside is the set-up is going to cost me more than the tank, water pump, and electrical to wire everything :unsure:
