"Scientific American Supplement No. 819, September 12, 1891"

The hydrogen
and oxygen, escaping through the upper orifices, flow to the
compensator. The apparatus is provided with an emptying cock or a cock
for filling with distilled water, coming from a reservoir situated
above the apparatus.
[Illustration: FIG. 4.--DETAILS OF AN INDUSTRIAL VOLTAMETER.]
The constants of the voltameter established by Commandant Renard are
as follows:
Height of external electrode 3.405 m.
" internal " 3.290 "
Diameter of external " 0.300 "
" internal " 0.174 "
The iron plate employed is 2 millimeters in thickness. The electric
resistance is about 0.0075 ohm. The apparatus gives 365 amperes under
2.7 volts, and consequently nearly 1 kilowatt. Its production in
hydrogen is 158 liters per hour.
It is clear that, in an industrial exploitation, a dynamo working
under 3 volts is never employed. In order to properly utilize the
power of the dynamo, several voltameters will be put in series--a
dozen, for example, if the generating machine is in proximity to the
apparatus, or a larger number if the voltameters are actuated by a
dynamo situated at a distance, say in the vicinity of a waterfall.
