Show New Meter Successful. The latest development In metering appliances is a coal meter built on the principle of a water or gas meter. This Instrument was devised primarily to measure the coal consumption of factory fac-tory boiler rooms, but It may find a wider application on a Smaller scale. It operates on the same principle as a water meter, the stream of broken coal pouring down a chute and turning turn-ing an Inclosed vane. The meter can also be used for grain, according to the Inventor. Its use on coal was entirely successful. |
