The disclosure is directed to reservoir assembly for storing hydrogen peroxide for use with a hydrogen peroxide vaporizer in association with a filler. Which includes a fluid chamber, a float member and a column level sensor. The float member is positioned within the fluid chamber. The fluid column level sensor is positioned at or near the upper end of the fluid chamber. The float member is configured to absorb the vibrations, turbulence and bubbling caused by the fluid movement and degradation. To that end, the float member is configured so as to be partially submerged. In addition, the float member includes an outer surface that has both passageways and sidewall guide surfaces which facilitate proper tracking within the fluid chamber, while also allowing for the directing of fluid movements around the float.
