Abstract

228,193. British Thomson-Houston Co., Ltd., (Assignees of Thompson, L. W.). Jan. 26, 1924, [Convention date]. Indicating.-In connection with a number of measuring devices each comprising an indicating circuit in which the current is varied according to the value being measured and wherein the several measuring devices have different constants, a circuit is associated with the indicating circuits for totalizing the values being measured. As shown, the flows of fluid through separate conduits are totalized on an instrument 14 such as a watt hour meter, an ammeter &c. in a circuit 13. Flow meters 1 .. 3 vary the alternating current in indicating circuits 4 .. 6 according to the flow of fluid through the conduits. Each indicating circuit contains measuring instruments 12 and is supplied from common mains 11. The totalizing circuit 13 is linked with the circuits 4 .. 6 by transformers 18 .. 20, the current ratios of which are such that the different constants of the flow meters 1 ..3 are reduced to a common constant in the circuit 13. Specification 214,632, [Class 69 (i), Hydraulic apparatus &c.], is referred to.
