Small Water tank level gauge help

[BLTillson]

Greetings friends,

I am in the midst (year 2 ) of designing and building my very own teardrop trailer. I am ordering the little water tank on Monday. This is a small tank, only 11 gallons installed right above the axel and under the bed. I am looking for a solution for a decent water level gauge. I can't use a simple closed tube because the the tank location. I could a tube on the side inside the compartment (see picture) but I would have to lift the bed and open the lid to see it. I need something electrical that comes in from the side. I also want to keep the cost down. The tank is from Plastic-Mart and is a model: R-RVB319. It will have the fittings installed where I choose. I have figured out my fill, vent and drain locations and wondering if I will need others for a gauge. It's not a huge issue and not a critical item, however, if I can find an easy solution I would consider it. Thanks all!

Also, since I am posting on the subject, here is my basic plumbing schematic.

Hey there,

For an affordable and effective water level gauge, you might want to consider a simple float switch sensor. These sensors can be mounted on the side of your tank and connected to an LED indicator or a digital display, which you can place somewhere more convenient to view. They're relatively inexpensive and can be installed with minimal hassle.

How about this simple DIY idea on a budget:

The probe, the contacts, and wires will have to be made of food safe materials.

Yup......not a whole lot different than the sensor system(s) in a towable RV camper. 3 or 4 contacts molded into the side of the tank, with the right sequence of wiring, and you have a rather simple and effective level "gauge"

I have this one and it works great. They also have a propane tank sensor you can also monitor in the same app.

x2 on the Mopeka. No need to drill a hole in the tank and it sticks to polyethylene. I'm on my second year and mine is still working great. It's compatible with Victron Cerbo GX too.
