I know that the manual says the max length of the pipe is 15". What would happen if I made it around 22" or 24"? Would it not calibrate correctly?

You should be able to achieve that without any problems.

Don't you have to change some code in the Water Level.cpp?

This is from the Water Level's Limitations thread http://forum.reefangel.com/viewtopic.ph ... imitations

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.

Or has this been changed in recent library updates?

That's for when you use extra long pipe. I think for that size, it is not necessary.

rrodriguez was using a 23" tube in that other post and lsmsclst is taking about using a 22" or 24" tube.

I still think that for that length the gain change is not needed, but further test needs to be done.
Just dip the entire pipe in water and watch what the calibration number is like. If it tops up, you will need to change the gain.

Ok. Just double checking for when I start to setup my ATO & NSW system.

I will try it tonight and let you know.

Hy there

I use a 23'' (give or take), but I had to change the gain value on line 55 of WaterLevel.cpp, otherwise the reading gets nuts.

After that.. works perfectly

Thanks Rafa that is the way I read it.
