Not illustrated. 1917 Excerpt: ...diameter of the pipe, to which the contemplated attachment is to be made, rather than measuring the quantity which the pipe can deliver. The writer believes that there is but one reliable and satisfactory method for practically determining the proper maximum capacity of a meter to be applied to a service, namely, to insert a meter in circuit, open all the valves or faucets and time the operation of the meter for one, five or ten minutes. Thus, if a f-inch meter has been set and its full delivery is only, say, 1 cubic feet a minute, then in the majority of cases a f-inch meter would satisfactorily replace it and so on through the range of sizes. The Committee on Meter Rates examined its statistics to ascertain how much water was ordinarily passed by meters of different sizes. This study rested on the fundamental assumption that the largest meter in any system supplies that service in the system from which most water is drawn; and that all the other services are to be assigned to the meters of the several sizes in the order of their outputs. This is not strictly correct, Jour. N.E.W.W. Assn., Vol. VIII, 1894, p. 63. ORDINARY RATES OF OUTPUT 113 but for practical purposes it may not be much in error, because there are bound to be as many larger meters coming under any given limit as there are smaller meters exceeding it. There will be some variations both ways, but in the aggregate these will balance. The limits that were found were as follows: Examined in this way, it appears that the normal maximum output for one f-inch meter (data for 11 systems) is 705 gallons per day. In other words, averaged by systems there are as many f-inch meters as there are services from which less than 705 gallons per day are drawn. The average output from all the f-inch meters i...
