I just got a used water level expansion, The instructions indicate that one should use pvc, but don't say how long it should be. The unit came with about 5 inches of clear 1/2" plastic tubing attached. Is there any reason I should replace it, lengthen or shorten it?

I don't think the length really matters, up to a point (few feet?). Just use whatever length fits your application.

Were they using the 1/2" tubing instead of PVC? I wouldn't think it would matter.

Yep, 1/2" tubing instead of pvc. It's glued on, so hopefully it will work as is. I'll give it a try. Thanks for the reply!

9" PVC is what comes with the unit, but you can use what ever length you need up to about 15 inches then there is some code that you need to add for longer pipe to work properly.

Check this thread.

Line 55 of WaterLevel.cpp
Change this:

Code: Select all

	addr+=0x03; // Programmable Gain

To this:

Code: Select all

	addr+=0x01; // Programmable Gain

Let me know if this helps.

Thanks for the post, I did a search, but I never bumped into that thread! Very helpful.

No Problem.
The only reason I know about it is because I'm going to be putting a pipe top to bottom in a 20 gallon Brute Trash can.
About a 20" pipe.

I think it's titled "Water Level's Limitation".

So, if I understand correctly, the idea is you want to place your sensor at the high water mark, and the pipe will go all the way to the bottom of the container.

Depends on what you are trying to accomplish.
My sump is like that, but the overflow is not. I just want to measure to top end of the overflow, so the pipe never reached the bottom.

When I was looking around for info on how to set up the adapter/pipe assembly I saw a photo of your overflow setup. Very cool idea!

I'm going to measure full (100%) and empty (0%) in my Brute Trash can.

My RO/DI unit will automatically turn on when level is reaches 0% and turn off when it reached the 100% mark.

Great idea! Now I just need a half dozen of these things!
How do you connect to Reef Angel Controller? Do you use a long bus cable?

1/2 dozen of the Water Level sensors?

Roberto developed a multi Water level senor that has 4 units in it, so that plus the original single unit will give you 5.
That is the max you can have I believe.

I have the units mounted in my stand with all my other equipment and I'm going to use long tubing to the unit to the PVC tube.

Ah, I didn't know you could extend the 1/4" tubing. Any idea how long it can be?

I haven't tried it yet. I'm looking at about 20'.
I already extended 1 to 10' to reach the 10 gallon ATO tank I have set up now.
