Abstract
112,672. Candy, F. P. Jan. 22. 1917. Liquid-meters.- In a water-filtering plant, the inflowing water supplied by a pipe 7 passes through a weir box 8 and over weirs 9, and a float 23 in the weir box is connected to an index 27 which indicates the rate of flow. A layer of gravel 21 supported by a perforated plate ensures an even upward flow of water in the weir box.
