Abstract
1414551 Electrolytic solutions for bubble sensors NORTH AMERICAN ROCKWELL CORP 26 June 1973 [26 June 1972] 30282/73 Heading G I N A bubble level sensor 10, Fig.1, comprises a cylindrical container 20 with a central electrode Z in the base, and a cap 30 which supports two pairs of diametrically opposite, curved electrodes Xl, X2 and Y1, Y2. The container 20 is filled with an electrolytic liquid 22, Fig.2, through a hole 25 in electrode Z, leaving a bubble 27 which is centralized by adjustment of the cap 30. The differential impedance from electrode Z to electrodes Xl, X2 and Yl, Y2 measure the tilt in X and Y planes. The electrolytic liquid comprises an alcohol containing a volatile ionizable acid, base or salt. Examples of suitable materials are given.
