AliCat Scientific Flow Meter, Calibrated for HHO.
Model M-20SLPM-D/5M, GAS HHO
Steve, at GreenFuelH2O, demonstrates the accuracy of the bottle fill
method, versus the AliCat. The bottle fill method is surprisingly
accurate in comparison. His first experiments with the AliCat were, in
my opinion, very inaccurate; LPM was about 40% high. Steve discovered that the
moisture was affecting the reading. So to solve the problem, he added an
additional Dryer to filter off the moisture. Steve noticed that his
larger cells measured around 100 ML PM more than Faraday. That could be
because of the pressure needed to route the gases from the cell, through
the Alicat, and then through the bottle Flow Meter. A slight back
pressure could be the reason. At any rate, Steve has justified the use
of the AliCat if moisture is minimized. Thank You Steve, at
If you as an HHO Company are using this AliCat Flow Meter, your
measurements will be at or close to my Faraday Cell Configurator calculations,
if and only
if you minimize the moisture. The video below proves it.
In GreenfuelH2O's words, Alicat really knows how to measure gas. That
is what they are in business to do.

If you place an order, you must tell them you need HHO included.
Model M-20SLPM-D/5M, GAS HHO
I have been
telling people that you can not measure two different gases with the
same meter; specifically hydrogen and oxygen. As it turns out, I am
wrong. A company by the name of Dwyer can custom make a Flow Meter for
Call toll free at 1-800-872-9141 and ask to speak to a
Flow Meter product engineer.
Tell the engineer your are measuring mixed Hydrogen and Oxygen
The ratio of the gases are 66.666% Hydrogen and 33.333% Oxygen.
They will Custom Build the meter for you; at an expense.
you tell them the wrong mix ratio, the meter will provide the wrong
Personally, I would ask them the percentage of accuracy +/- what %.
I would also ask them "what part of the ball is used to read the
measurement" (top, middle, bottom). It makes a difference; you see, the
bead height is 2 of the meter marks (200 ML each mark). So there could
be a 400 ML difference, depending on the position of the bead. That is a
lot of gas.
Flow Meter makes an approximation/ estimation of the
gas flow in exchange for ease of use. This is, at best, a replacement to
manual measuring gas flow using a Liter bottle submerged into water and
timing it. This product offers a workable measurement to researchers and
hobbyists who need a ready product which serves the purpose in a trouble
free manner, rather than scientific accuracy of a high end... expensive
piece of formal research experiment,.
Not HHO Flow Meters
Super Gen Series Flow Test. This guy knows Air is not HHO yet he
tries to convince you his cell is putting out 8 LPM. Air does not weigh
the same as HHO, thus the measurement is false. The inconsistent level
of the measuring bead is a testament to the poor internal design of this
particular tube cell. HHO is having to build up internal pressure in
order to escape. Shameful.

This guy calls the Flow meter a
professional meter, made by Dwyer, specifically for measuring HHO. The
meter is clearly labeled "Air".
The cell has a serious flow problem. Backpressure is forcing gas out
of the bottom water fill hose.
Pulsing of the gas is very visible; caused by the top outlet port
being too far down from the top of the gasket. This creates a chamber
for the gas to collect in. Also, the plates have only one hole in them.
They alternate up and down, every other plate. This causes cell chambers
to fill with gas, which completely pushes the water out of the next
chamber. A serious design flaw. Hydroclubusa does this too.
How Not To Measure HHO
The worst demonstration I have seen.
The bottle is not completely submerged.
The cap is put on the bottle 6 seconds before the timing starts.
The bottle is collecting HHO during that time.
