"For gas measurement, the inverted 2 liter bottle and stopwatch always seemed a little too basic. In the early days I rigged up a eudiometer
that was basically a long tube with at valve at the top and three valves at the bottom. To fill the tube, with water, the upper valve was opened
to allow the air to escape. One of the bottom valves went to a cold water supply. The other went to to the HHO generators. The third was a drain plug.
To operate the upper valve was opened to allow air to escape. The water supply valve was opened to allow water to fill the tube. The HHO
supply line valve would have been closed during this procedure as would be the drain valve.
Then as the water level rose in the tube to about 95 percent of its capacity, the water input valve would be closed and the top valve would be
closed. The drain plug would then be opened and because the bottom of the eudiometer was submerged. the vacuum kept the water from
draining out of the tube. Then the valve to the HHO generators would be opened and because the eudiometer stand was below the level of the
HHO tubes and since the gas was collected at the top of the cells no siphoning would occur. This was all manual control with ballcock valves similar
to what Charlie H was doing on the buggy.
I always wanted to automate this with an electric eye or float to sense when the tube was full and to shut the upper air ecape valve and close the
water intake. To measure the gas ouput ,at the push of a button, the timer would start , power would go to the HHO cells and the bottom solonoid
valve would open for drainage as the water was displaced from the tube.
As the gas level displaced the water and it fell below a certain level, a photo electric eye or other water level sensor, would turn off the timer
The sensors were to be placed so that one liter of water was the start and end point. It was felt that to build larger gas containment volumes such
as 2 to 5 liters was too risky in terms of spark or static ignition of the HHO. The automatic controls never got built and a modifed gas
flow meter form a welding set was used in its place"
