1. A lubrication system, comprising:
a floater container including a floater compartment that contains a buoyant floater;
wherein the floater container is coupled to a housing bulkhead;
wherein the floater container includes an inlet opening in a first wall that is off-axis from a horizontal plane and forms an angle with a second wall;
wherein the housing bulkhead includes an outlet opening positioned lower than the inlet opening and provides fluidic communication between the floater compartment and a rotating component compartment that contains a rotating component;
wherein the housing bulkhead includes:
a first side that is coupled to the floater container and defines a portion of a boundary of the floater compartment; and
a second side that forms a portion of a boundary of the rotating component compartment; and
wherein the housing bulkhead divides a compartment from the rotating component compartment; and
a conduit extending vertically from the floater compartment and including an opening that is positioned above a lubricant level in the compartment and profiled to provide fluidic communication between an interior of the floater compartment and the compartment.
