Liquid Level Indicator

The optional Liquid Level Indicator (LLI) consists of a hollow metal tube inserted into a special
fitting in the top of the 125, 200, 350, 600 or 900 lb HFC-227ea cylinder. See Table 3-5 for
part number information. The indicator is provided with a graduated tape which senses the
position of a toroidal magnet encased within an internal float riding on the liquid surface. The
graduations on the tape indicate the liquid level within the cylinder (see Figure 3-10).
