Meter Test at Syracuse.
At Syracuse, N. Y., has been completed a test of meters which has been in progress for a month at the repair shops of the bureau of water. Four old meters and four new ones of nearly as many kinds were selected for the purposes of the tests, both the disk and piston types. At first, all the meters were connected up tandem-fashion, so that the water which passed through one must necessarily pass through all of the others. Thus each was tested as to its capacity to register flows of water 1/2-in., ⅛-in., 1-16-in. and 1-32-in. in diameter. Afterwards each was tested separately as to its accuracy of measurement and registry by weighing the water anil comparing the record of pounds with the record in gallons. Thirty thousand cubic feet of water—enough to supply one family for between eight and nineyears, were run through the meters. One of the old ones, which had registered the consumption of about 30,0oo cu. ft. in actual service, stopped registering during the test. The other three made respectively 30,655, 30,076 and 30,004 of the 30,000 cu. ft. which passed through thun during the test, and meanwhile the four new ones were making 31,388, 31,477, 31.304 and 31,627 out of it. On the percentage basis the tests demonstrated that one of the new meters is absolutely correct. Another ranged front accurate to 6 per cent, slow, another from accurate to 2 per cent, slow, and the fourth from accurate to 4 per cent. slow. One of the old ones, by which the city has sold 60,000 co. ft. of writer, ranged from I to 3 per cent, slow; another from accurate to 2 per cent, slow, the third from accurate to 2 per cent, slow and the fourth stopped registering during the test.
