Tank sensor recommendations
Looking for suggestions for a reliable tank sensor system. I read about the See-level system and wondering if anyone has installed it and if it worked fairly well.
Had to replace my fresh water tank and of course Marathon had changed the sensor interfaces etc. Now all three tanks are pretty unreliable. The fresh tank stays on 50% and the dump tanks read either 20% or 80%. Just want a simple reliable system that has a dedicated readout. Thanks

Tech Edge iSeries with optional inside take sensors. I mounted the readout in the bathroom.

Chris,
The only way I can get a good reading on my tank sensors is to manually disconnect the wire that is on the little circuit board, count to 10 and reconnect. At some time from 5 minutes to 3 hours later Tech Link will show what looks like a good reading. I suspect that the little PI computer is not scanning the tank sensors on a regular basis and by doing the manual disconnect/reconnect it forces an update. Just a guess on my part.

Chris, I have the See-Level sensors on my tanks. My tanks are tall enough to need two strips to read from top to bottom. So I purchased two systems.
I stacked the strips to read the whole tank and installed one readout in the utility bay and the other inside in bathroom.
I thought about only one system with the strips installed at the top of the tank. This would read when the tank was beginning to be full and would make the system more economical.

Installed Sea-Level 4 yr ago two sets because of tall tanks one read out in bay and control panel. Used existing wiring. Easy to hook up. Highly recommend

I thought See level tank monitors were for plastic tanks only. Do they have a version now for stainless / aluminum ?

To use them on a metal tank, you have to tap into a low discharge line with a T. Probably the macerator pipe will work, and use a plastic stand pipe coming out of the T. The pipe will need a vent line in the top returning to the tank so you do not get odors, but any small line will work. The stand pipe of plastic will fill at the same rate as the tank so the sensor reading will be accurate.
Same principle will apply to the water holding tank and that will be easier to hook up a plastic stand pipe and it will only need a cap with a tiny hole in the cap.
If I wanted to monitor tank levels I would only use one for fresh water and as I do now just never fill with water unless dumping the holding tank.

Those are soon great ideas Jon. My original tank monitors have never worked right, fresh water accurate about 15% of time and the holding tank always reads empty. Based on your setup, do you wait to dump until the fresh water tank is empty?

Thanks for the replyies. I’ll see what Jeff feels will do best. Hope I can get something semi-reliable.

Dick, Like your coach mine has Headhunter level sensors and they work so I can monitor what is going on. I have a long time habit of never ever taking on water unless I have dumped my holding tank. My holding tank shows nearly full when I am down to about 20% on water so at that point I am going to dump.
When we are hooked up to water and sewer I rarely let the water get as empty or the holding tank as full. When dry camping with no hookups I always hope to use the gray water by-pass. That way I am assured I will not overflow the holding tank.
If my Headhunter sensors failed I would consider using the system as described above, but only on the water tank since my practice of dumping before filling has kept me out of trouble.

Trying to locate my coach tanks sensors…reviewed the postings and they were supposed to be on passenger side / water bay – main water pump bay behind the panel. None found…took pics and sent to Marathon, tech reply was that he could not see the pumps nor the tubes that would hook to the pumps…he suggested that maybe the system was upgraded to “pressure pad style” and installed on driver side of the coach. Records I have do not show any “upgrades” unless these were installed when the coach was built in 2000? Looking thru the schematics, the tech did mentioned that it was a special build…whatever that means…
I assume these will be on the water bay compartment, what am I looking for?
Pads mounted on side of the tanks or?

Dorel,
On our coach on the curb side water bay, above the water pump we have a
shelf that has three little white 2 x 4 aquarium type air pumps that measure
the levels in our tanks. They work off a timer, so if you wait 5 minutes, you will
hear one turn on and pump some air.

Dorel,
We had our sensors, which used the aquarium pumps, replaced two years ago with the pressure pads. If you have the pressure pads, you can take the panel off that the faucet is mounted on, and you should see the pads adhered to the tanks. Black and gray pads are mounted on the driver’s side, and the fresh water pads on the passenger side.
