Abstract

848,722. Indicating liquid levels. FRANCAIS ETAT. Nov. 8, 1957 [Dec. 21, 1956], No. 34827/57. Class 123(1) [Also in Groups XXXIII and XXXV] A liquid level indicator comprises a float 11 on a pivoted arm 1 transmitting its position to an electric indicating device through a sealed casing 9 by means of a magnetic coupling (see Group XXXV). If desired, two transmitters feeding a single receiving instrument 14, as shown, may be used to cover a wider range of level.
