The Finished Rotameter Project

I go over the finished Rotameter I intend to use to measure HHO gas production with. I also give a little demo of the thing in action when I blow air through it.





Works for me.

Introducing the Rotameter

I went out on Ebay and acquired a Rotameter to measure my gas production with. While using pop bottles is a cheap way of doing so, I wanted to be able to monitor the gas flow more often to see if there is a distinct correlation between heat, current and gas production. Measuring once in a while with a bottle doesn't really do that, without making a mess of course.

The answer was the Rotameter. This one had too much capacity for the current projects, but I was able to get another tube with the capacity range I'm likely to see for now. Even with the second tube I paid less than retail for the whole rig.

Sweet!

Building a Housing for an Electric Watt Hour Meter

I decided I needed to know how much electricity I'm using to do my experiments, so I went out and shopped victoriously on Ebay for an electric meter. The meter I bought is an older model, a General Electric GE IW-70-S which only sports 4 main wiring blades. The newer model I-70-S has 5 or 6 main wiring blades and will be wired differently than the one I have.

Once It arrived in the mail I was left with the dilemma of how to actually put it to use. The answer showed up in the form of a woodworking 101 project.



The entire project took about 4 hours of my time over two days and cost me a total of around 60-65 Dollars. It would be more or less depending on the meter since they are running 10 to 40 bucks and what bells and whistles you would want on your housing.

Here's some support info for the meter housing.









The list of wiring guides are at the General Electric Meter Wiring Guides in case you are using a different model of GE meter.

And the Parts List

• (1) Carry handle
  
• (1) used extension cord to be remade into the power cord (20 feet will do)
