Abstract
1396021 Measuring fluent levels electrically METRITAPE Inc 14 Sept 1972 [15 Sept 1971] 42723/72 Heading G1N A level transducer comprises a base conductive strip covered with a helical resistance winding and inserted vertically in a container of fluent material whereby the material in the container forces the resistance winding against the conductive strip to short-circuit part of the resistance and the value of the remaining resistance is indicative of the material level. The invention relates to a protective housing for the transducer 23, Fig.4, comprising a channel 34 and a thin facing strip 40 covering the actuatable side of the transducer and supported in grooves 38, 39 in the sides of channel 34. Details are given of different types of assembly, with and without a facing strip 40, and of an assembly for mounting the transducer in a container Fig.12, (not shown).
