SeeLevel Tank Monitor System

I don't know what the difference "before or after 2009" is but I installed my 709-PH sytem in 2006 and have been very well pleased with it.

My experience with the See Level system was quite disappointing. As recommended, I temporarily mounted the sensors in order to determine the best vertical location on the tank. However, when filling each of the four tanks with a five gallon bucket, it became clear that the sensors were not measuring the five gallon increases the same. One tank might increase it's level by 25%, and another tank would not change at all.

After speaking with their tech support it was advised to place the sensors on the lower portion of the waste tank, thus allowing for outage at the 100% level and the inverse for the fresh water tank. And yes, the installation instructions were closely followed.

In addition, they suggested that the inaccurate reading might be to scum build up on the tank walls. After purchasing their recommended tank flush product, there was no change in the accuracy of the sensors.

I've developed a chart for each tank, and it's relative percentage of capacity.

Thats why I would not recommend this product. Hope this helps.

There are a couple of notes that I should add.
1. Wish I had installed 709 PH SeeLevel system. After I installed the 709. I found that circuit board on original monitor is all in one. Not possible to separate.
2. I should have mounted the sensors on side of black and gray tanks to more accurate reading of full.
Beyond that I am very happy with the install.
Here are some pictures.

I installed my SeeLevel II system in 2008, and couldn't be happier with it. The percentage readings are much more accurate than the standard "Empty,1/3,2/3,Full" systems. The installation is comparatively easy if you have reasonable access to your tank walls and the existing sensor wiring.

I've also installed the SeeLevel, and I also used the wiring from the other sensors that never worked right.

Generally, I've been pleased. The only negative I can come up with is that sometimes, when it's really wet out, the sensors won't read properly. But that probably has more to do with my install than the sensors themselves.

I'd say go for it.

I installed a See Level 709 last fall. Great product and easy to install using wires from original sensors that never worked.
