Tank Monitor - SeeLevel ?

[Marksman]

I have a sight tube on my water tank, use a stick on my fuel, and the holding tank bag is pretty self evident as well. Veeerrrrryyyy low tech. uses no power at all. But certainly not a good solution for everyone.

Garden cane low tech approach for fuel tank here too

Chris,
Thanks - yet another option (I missed Peggie's reference earlier) the Electrosense monitor uses 5 sensing rods cut to different lengths to measure the tank. Apparently Electrosense tries to configure the rods based on tank size and shape. The 9 volt battery option is nice, simplifying installation.

I have to measure the clearance above the holding tank. My feeling is that I have about 1/2" between the bottom of the cushion and top of tank (top mounted on plywood). That's why I'm not sure if any of the top mounted solutions will work.

Each manufacturer claims their solution is better than the others. We have air pressure, electrical capacitance, ultrasound, measuring rods,....... Amazing how many options for such a simple concept - clearly one has to be better than the others!

My understanding is the hose from the tank doesn't have any low spots to avoid erroneous readings, I don't think it has anything to do with siphoning.

James S,
Per the Tank Tender installation instructions, they say to "Keep tubing above the level of the tank to be measured.....". I'd have to run up and over the headliner to properly install!

Where's your tanks Don?
Yes...I can see them possibly siphoning if they are cut and fall below the tank.
If properly installed I wouldn't think they would have much chance of being cut and if they are, they would only fall below the tanks if they were not properly secured.
Really seems a long shot, but certainly possible, thanks for pointing it out Don.

I have Tank Tender's on a 4 tank system. I love it,and I think the real advantage is that the system doesn't use any electricity whatsoever and is totally independent of any batteries or wiring at all. So not only does it pull no juice, it will still work when all your electronic doodads are dead. Mine was installed at the factory in '83, I have the original manual, and it works great. No replaced hoses. Nothing ever gets in the hose but air if you install it right. I have 1000 gallons of tankage so it's nice to be able to keep an accurate count of what's where quickly.

Yes, the tank tender is my current system too... it's as good as can be for the non-NMEA crowd imo.

ciao!

I've heard that the SeeLevel works fantastically for any RV unit. The only qualm that I've heard is that the system goes haywire if it comes into any contact with a liquid, as it isn't water tight. Not sure if the system can come with an optional enclosure or not. For a boat, you may want to search for a Water Level Sensor that comes with a water-tight case. If you aren't concerned with the SeeLevel getting wet, I probably would consider getting that.

I don't think Seelevel would last a week at sea...

Does anyone have a recommendation for a floatswitch in a dieseltank? I need to reconfigure my day tank so that it switches on the pump at low level, switches of at high level and sounds an alarm if below low level.
