Abstract

1,068,581. Liquid level indication; pressure gauges. T. E. M. SALES Ltd. March 24, 1964 [March 25, 1963], No.11738/63. Headings G1H and G1L. In a device, such as a gauge glass or manometer comprising two tubes 16, 7 connected at their enclosed tops by nipples 11 to sources of pressure, the level of the liquid in the tube 7 is shown on a screen 66 as the projected image of a transparent calibrated scale 33 bouyantly supported by a float 30 between windows 41, 42 and illuminated by a lamp 45. A convex lens is arranged behind the window 42.
