Hydrogen peroxide reservoir assembly including a float position sensor for determining liquid level

Abstract

A reservoir assembly comprising a lower manifold, an upper manifold, a reservoir body, a float member and a sensor system. The upper manifold has an upper cover placed over a central bore, and sealingly engaged therewith, the upper cover being at least partially transparent. The reservoir body has a lower end sealingly engaged with the lower manifold and the upper end sealingly engaged with the upper manifold. The float member is positioned within the reservoir and can slidably move between the upper and lower manifolds. The float member has an upper target that is substantially parallel to an upper cover positioned on the upper manifold. The sensor system has a float position sensor positioned over the upper cover and targeting the upper target of the float member to, in turn, determine the position of the float member relative to the float position sensor.
