Abstract
1410742 Fluid pressure switches ENVIRONMENT ONE CORP 13 Feb 1973 [15 Feb 1972] 6912/73 Heading H1N In a sewerage liquid level sensor comprising a fluid pressure diaphragm switch 10, Fig. 1, above a column 11-17 of trapped air or other fluid with the lower end 17 immersed in the liquid, a float operated valve 14 is arranged in the column to prevent a rise in the level of the liquid past the valve 14 in the event of a leakage fault in the measuring device 10 such as caused by a diaphragm leakage. The valve 14 comprises a ball float 19, Fig. 2, resting on projections 20 whereby the air or other fluid of low specific gravity may freely pass. In the event of a rise in the liquid level, the ball 19 rises into its upper seat 21 and prevents a further rise in the liquid level and thereby protects the switch from contamination.
