Example invertible metering apparatus and related methods are disclosed. An example apparatus disclosed herein includes at least one processor and memory including instructions that, when executed, cause the at least one processor to at least: determine an orientation of a housing; determine if a housing is in a mounting orientation; in response to determining that the housing is not in the mounting orientation, initiate a first alarm; in response to determining that the housing is in the mounting orientation, determine an orientation of a stencil; determine if the stencil is in an upright orientation; in response to determining that stencil is not in the upright orientation, initiate a second alarm; and in response to at least one of the housing being in the mounting orientation or the stencil being in the upright orientation, assign a light pattern to a plurality of lights associated with the stencil.
