A vertically mountable sight gauge is comprised of one or more serially connectable sections for visually determining the level or the volume, or both, of liquid stored in a container. Each section has an upper and lower housing. Each housing has a passage therethrough with a first end and second end, is surrounded by a flange, and is attached to the ends of a straight length of substantially transparent, flexible pipe. The pipe is surrounded by a cylindrical, substantially transparent, rigid shield and a cylindrical, substantially transparent, rigid sleeve. The bottom end of the sleeve is surrounded by a shoulder. The outer diameter of the top end of the sleeve is less than inner diameter of the shield, such that the sleeve telescopically engages the shield. Biasing means bears against the bottom end of the shield and the sleeve\s shoulder, surrounds and overlaps the sleeve, and urges the shield against the upper housing and the sleeve against the lower housing. The second end of the uppermost housing\s passage is placed in communication with the interior upper region of the container, and the second end of the lowermost housing\s passage is placed in communication with the interior lower region of the container. A float is placed in the pipe to improve the visibility of the height of the column of liquid contained. The upper housing\s and lower housing\s passages contain means for preventing the escape of the float without preventing the flow of liquid through the passages.

A vertically mountable sight gauge, having one or more serially connectable sections, for visually determining the level or the volume, or both, of liquid stored in a container having upper and lower interior regions, said gauge comprising: (a) for each section, a straight length of substantially transparent, flexible pipe; (b) for each section, an upper housing and a lower housing, each housing having (i) a passage therethrough having a first end and a second end, said first end of each said passage being attached to an end of said flexible pipe, and (ii) a flange that is substantially concentric with said second end of said passage; (c) for each section, a substantially transparent, rigid shield surrounding said flexible pipe, defining a continuous, inner wall surface and a continuous, outer wall surface and respective inner and outer diameters, and having a top end and a bottom end and a circumferential top edge that conforms to and abuts said flange on said upper housing; (d) for each section, a substantially transparent, rigid sleeve surrounding said flexible pipe, defining a continuous, inner wall surface and a continuous, outer wall surface and respective inner and outer diameters, having a top end and a bottom end and a shoulder surrounding said sleeve\s bottom end, said shoulder having a circumferential bottom edge that conforms to and abuts said flange on said lower housing, and having an outer diameter that is less than said shield\s inner diameter, such that said sleeve telescopically engages said shield; (e) for each section, resilient biasing means bearing against said shield\s bottom end, surrounding and overlapping said sleeve, and bearing against said shoulder, so as to urge said shield into engagement with said upper housing and said sleeve into engagement with said lower housing; (f) means for placing said second end of said passage in said upper housing of the uppermost of said serially connectable sections in communication with the interior of the upper region of said container; and (g) means for placing said second end of said passage in said lower housing of the lowermost of said serially connectable sections in communication with the interior of the lower region of said container.
