See Level tank monitoring system install

(1/2) > >>

SargeW:
This is a thread from another forum that I had made a few years back.  The install was was fairly easy but took some time to complete.  I wanted to share it with the members of this forum. 

I spent two days this weekend working on installing a new tank monitoring system from Garnet industries called SeeLevel II. It is a huge step forward in monitoring your fresh, black and gray water systems, as well as LP levels and Battery condition.

The mounting box was sourced by the member of another site known as "Flyer" from the Home Depot really made the install professional looking.

Mounting Box

However, a few points here that are particular to my 06' Meridian. First, the really big challenge was to remove the metal facia in front of my black and gray tanks. The facia has 4 different water outlets on it, all of which require you to reach around and unscrew the connecting water lines. There are also two electrical switches with several wires, and the whole thing was held on with about a dozen screws. Most of this had to be done with the use of a mirror to see behind the panel, and detach the fittings by brail. However, putting everything back on was a lot easier.

Water bay cover

I used two displays. One on the inside on the "One Place" panel, and the other in the sewer bay to monitor levels when dumping or filling fresh water tanks.  I painted the inside box black before the install to match the existing panel. 

Inside box applied over the old monitor switches.

The other major help was going to the Winnie site here on this forum, and printing the section on the electrical schematics that diagrams the "one place" panel. It really helped to be able to identify each incoming wire and what it powers.

Wiring the fresh tank was not bad at all. I just put the upper and lower senders on different sides of the tank. All the wiring was accomplished by using the existing sensor wiring.

I moved fairly cautiously and took about a day and a half to complete the install. If I were to do it again, it would be about half as long.

A truely great mod, and not too difficult.

Marty - great project and many thanks!!

Good post Sarge!

A couple of questions for you

1.  Was the probeless monitoring system by Winnebago giving you fits?
2.  What was so bad about the OEM monitoring system to make you change?

Off topic questions and I appologize to Canfield in advance:

1.  What is the blue stuff on the floor of the water bay?  (I installed the alum. bubble wrap insulation in my compartment)
2.  Is that white circular item a sewer hose support that is cut in at the back of your comparment?  Did you do that

SargeW:
Good questions Mark. Actually it was working exactly as designed.  The problem was that since the OEM unit measured in 1/3 units, when the fresh water tank dropped below 1/3, I either had 30 gallons, or empty.  As soon as the water dropped 1 gallon below the 1/3 mark, the empty light would come on.  The same with the black and gray tanks when filling. The tank 2/3 light would come on as soon as the levels reached that point, and you had no further info until you were full.  That can cause a bad situation when the DW is showering and the water starts to back up in the drain.......

The system is worth it's weight in gold!  If one were to never dry camp it may not be an issue, but we like to hit the beaches and national and state parks.  Most don't have a sewer dump at the site.  In my opinion, that system was the weakest link in the entire RV.  Now it works well.

I have also installed a Sea Level II gauge.  It is the best mod I have done.  It is more accurate then the OEM gauge which makes it very helpful when dry camping.  If you are interested in this mod I have many detailed photos of the installation and a detailed write up.
