Finally got around to installing the SeeLevel setup, since I had the water reel removed for other issues. I wanted to have one display in the wet bay and one in the interior. Since our tanks are so tall, I would need 2 of the sensor strips per tank, so it worked out to purchase two of the Garnet SeeLevel 709 kits to get everything I needed.
Then I purchased a roll of 18/4 with colors similar to the wiring that came with the See Level kit. ( 100 ft. 18AWG Low Voltage LED Cable 4 Conductor Black Sleeve In-Wall RGB... ). Since I was having to re-wire for the new fresh water reel, I added an additional pigtail from that power/ground to power the SeeLevel system. I then ran the 18/4 wire across the top of the black tank from the street side where the first monitor would be in the wet bay, to the curb side where I would access the end of the tanks for the sensor strips.
First I cleaned the end of the tanks with alcohol, then hit them with some 60-grit sand paper, then cleaned them with alcohol again. Like others I have read on here, rather than using the adhesive on the back of the strips, I used Gorilla tape to mount the sensors, in case I needed to move them for calibration. I used two of the standard ES strips for the black and gray tanks. I cut 3 sections off of each strip to make it fit properly.
The fresh tank in my coach is "L" shaped at the curb side end. The bottom section is about 8" tall and extends about a foot further than the rest of the tank. The top portion of the tank is about 17" tall, so the ES strips would not work in this application. After talking with Garnet, I decided to purchase two of the 17" SS strips for the fresh tank. The top strip was used at full length and the bottom strip was cut to 7", the minimum length. Even though these are the maximum difference, and separated as mounted to the tank, they work perfectly.
I also wired the SeeLevel into the LPG sensor wires and that also works correctly.
The last step will be to fish a wire down from the cabinet over the microwave, into the basement and tie into the rest of the system. I left four open butt connectors for this, off the main wiring harness. That will have to wait until after our trip this weekend.
