  • The fact that you are putting so much effort into this is admirable.

    If you get it right, then that would be such a bonus!

  • You had me going there for a while...I was following so intensley, watching it unfold in my head.

    It is an idea that needs some polishing...I had not thought of a HORIZONTAL device to measure...this is an interesting concept!

    This needs some follow-up!

    Great idea!

  • Wow, thanks for the idea. I didnt think of, and I agree that the rising launcher method is wrong. It seems I guess in my opinion that puttin a little bottle (250mL) under water and bubbling up a tube seems accurate mostly.

    Thanks for the great information!

    Ben.

  • I think a more accurate version, because of the short amount of time it takes to fill 250 ml, would be to have a larger reservoir of water, say 1 gallon/4 quarts/close to 4 liters.

    This could be an idea...it would be nice to see 4 liters of water displaced from a jug in a minute...that is some serious production!

    I do not see it happening with most of our HHO devices and still have enough amps to charge the battery properly on the car.

  • I think once someone can verifiable mesure system flow they should setup a service for certifiing units that will be sold. Some what like UL does for tosters. if you want the cert you send your unit and get it certified and then you can put a certified by sticker on your product.

    Oh to live in a purfect world.

    what your doing is great

    would be nice if yoou posted a how to build your unit or a link to where its located

    Good Luck & work Safe

  • Now, that is an idea!

see all

  • I now have seen sid'e design and am inclined to agree with jamestfergussen about the accuracy issue. I am going to make one that resets itself and is incredibly accurate and will share my design when completed. Skewed results do nothing but lie to us all.

  • Check out zerofossilfuel's HHOmeter. The only back pressure it creates is the weight of the 520 ml plastic bottle, which can accounted for before the test. It is resettable on it's own, and gives very consistent results accurately. It is incredibly easy to make, and the concept can be adapted to make a much more accurately calibrated design. I agree with you on the point of accuracy. His design is affordable and able to be scaled up. Hope this helps.

  • I got tired of getting my hands wet. See my last video response.

    Pros:

    A lot of vertical travel for a very small amount of gas. Very fine milliliter measurements are possible.

    Only requires 350ml of water to run.

    Water is only used as a seal or gasket. It is not being pushed around during the test.

    Weight supported by the gas is constant throughout the entire range of travel.

    Cons:

    Needs a lot of headroom to be able to measure 1 liter of gas.

  • LOLLL you guys are too cool.

  • It does have a number of weakness though.

    - it is subject to error in atmospheric pressures and/or altitude where the test was conducted. We would need to figure out how to compensate for this.

    - it needs a small weight (less than 1 ounce) added to the lower side of the tank to keep the metering hole as the lowest point in the tank. This is to ensure gas does not escape early.

    - Ideally, The water tank needs to be large enough where the sealed chamber does not touch the side of the tank.

  • Well, I am not proud of it, but this is what I came up with. (See my video response above)

    The hoses/tubes are too much trouble to use and will not give consistent results.

    A sealed chamber with a metered outlet that has as close to neutral buoyancy as possible appears to give the most consistent and repeatable repeatable results.

  • Ok, there is the problem with using tubing.

    It is a royal pain to get all of the air/gas back out of the line to ready it for the next test.

    The larger the diameter of the tubing, the worse this issue becomes. That why I was was originally suggesting 1/8" tubing.

    Let me fade back and think about this some more.

  • I belive that I am going to make a 200 mL version. I already have a piece of 3/8" here not doing anything important.

    For a 200 mL 'standard':

    A 10 foot (3.048M) length of 3/8" (9.53mm) tubing with a mark at 2.763 Meters from the terminal end "should" represent 200mL.

  • Let me make a video to demonstrate. (I will need to run to the store for some 1/2" tubing.)
