Abstract
A container for holding a volume of fluid and having a housing defining an interior for retaining the volume of fluid; at least one in-tank tilt sensor connected to a controller and disposed inside the housing for generating a signal corresponding to a level of fluid inside the housing; and a support material attached to the housing and connected to the at least one in-tank tilt sensor to mechanically support the at least one in-tank tilt sensor such that the at least one in-tank tilt sensor is not in direct contact with the fluid inside the housing. The in-tank tilt sensor detects a change in fluid level which may only be caused by tilting of the imaging device. When tilting is registered, protective action is taken to prevent fluid from leaking.
