Journal of the Association of Engineering Societies . ich water gas,to be mixed with coal gas, and thereby bringing up the candle powerof the mixed eas to the desired standard. Wet Meter, Showing Drum from Outlet End. METERS. One of the first gas meters invented was made of bladders,which were so arranged that one bladder would be filled with gasfrom the holder, and in expanding would force the gas out fromanother one already filled, and a valve system would shift the re-sponsibility from one to the other, and thereby furnish a steadysupply. This shifting of the valves by suitable clockwork registeredthe number of times each bladder had filled and emptied. In thisway the amount of gas passed could be obtained. These bladders,owing to the properties of gas, soon became dried and cracked, andwere finally abandoned for improved devices. The wet and drymeters were the final results of experiments on these lines. The wet meter consists of a miniature overshot water wheelpartially submerged in water and revolving on a shaft.
