Hansen See-Level liquid indicators provide simple indication of true liquid levels in industrial and commercial refrigeration systems. When liquid is present the distinctive reflex lens appears dark; when vapor is present, the lens is light. The long universal housing provides adequate length for ease of welding as well as insulation clearance for low temperature applications. The optional frost shield facilitates clear viewing of liquid level under frosting conditions.
Application
