Abstract
A fluid level detector system, which may measure the amount of fluid in a reservoir, and may further trigger an alarm when the fluid level in the cassette reaches a low level condition. The cassette's reservoir may contain a transient sterile solution, which is moving through the cassette to be either cooled or heated in the heat exchanger area. The detection scheme includes a ring magnet housed in a float assembly located in the fluid reservoir of the cassette and, e.g., two magnetic sensors, such as may form a Hall effect integrated circuit, which may be fixed within the console.
