Abstract

617,942. Flow-meters. KRONBERGER, H. Oct. 1, 1946, No. 29282. [Class 69 (i)] [Also in Groups XX and XXXVIII] An arrangement for measuring fluid flow comprises a flow-meter having a sensibly linear response over a range of flow rates, shunted by a laminar flow resistance constituted by a large number of passageways such that the percentage change in branching ratio with the mass flow is less than the percentage deviation from linear response in the flow-meter. As shown in Fig. J, a flow-meter of the kind described in Specification 591,690, [Crroup XXXVIII], and having a linear range of 50 c.c./min. of air or 300 c.c./ min. of hydrogen at normal temperature and pressure is adapted by means of a shunt to measure flows up to six kilograms per hour of hydrogen at N.T.P. The shunt comprises a brass tube 16, 37 inches long and 2 inches internal diameter, coupled to a standard 2-inch pipe-line 19 by internally smoothed flanges 17, 18. The passage in the tube 16 is split up into approximately 1600 similar narrow channels by partitions formed by sheets 21, Fig. 3, of terminal copper foil, alternate sheets being corrugated and the remainder flat. The flowmeter is connected to the shunt by approximately 3 yards of capillary tubing 23 of 0.7 mm. bore and by two short tubes 22 soldered at right angles into the larger tube 16.
