Abstract

Использование: изобретение относитс к приборостроению и может быть использовано дл измерени уровн жидкости и сыпучих материалов. Цель изобретени - по- сышение точности измерени . Сущность: уровнемер содержит трубу 1, чувствительный элемент Ч, выполненный в виде гибкого полого корпуса, закрепленного вверху с помощью кольца 3. На внутренней поверхности трубы 2 и внешней поверхности корпуса датчика 2 размещен токосъемник в виде то- копровод щего сло . На токопровод щем слое корпуса по его длине установлены гибкие проводники 4. К токопровод щему слою подключен вторичный прибор 5, между корпусом элемента 2 и трубой 1 помещен мерный груз 6, выполненный с положительной плавучестью. 2 з.п. ф-лы, 3 ил.Usage: the invention relates to instrumentation and can be used to measure the level of liquid and bulk materials. The purpose of the invention is to improve measurement accuracy. SUBSTANCE: level gauge comprises a pipe 1, a sensing element H, made in the form of a flexible hollow body fixed at the top with a ring 3. On the inner surface of the pipe 2 and the outer surface of the sensor housing 2, a current collector in the form of a conductive layer is placed. Flexible conductors 4 are installed on the conductive layer of the housing along its length 4. A secondary device 5 is connected to the conductive layer, a measured load 6 made with positive buoyancy is placed between the case of the element 2 and the pipe 1. 2 s.p. f-ly, 3 ill.
