Abstract

655,367. Electric flow indicators. CLARK, W. J., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Dec. 30, 1947, No. 34640. [Class 40 (i)] A float 4 moved in relation to a conical portion A, B of a pipe in accordance with fluid flow alters the coupling between the primary 8 and the respective secondaries 9, 10 of a transformer, the secondaries acting differentially on a meter. Where the meter is a D.C. instrumment, temperature compensated rectifiers 15, 16 shunted by a resistor 14<SP>1</SP> are connected as shown, Fig. a. The flow may be read on the meter or on a potentiometer 23 or 25 used to bring the meter reading to zero. The float shown is of stainless steel and contains soft iron rods 5. The float is not necessarilv a float in the ordinary sense and may be a disc or a pair of discs separated by a tubular or other spacer.
