See-Level with Reflex Lens and Frost Shield

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. SEE-LEVEL™  liquid indicators are suitable for ammonia, R22, R134a, CO2 and other approved refrigerants.

Typical uses include: refrigerant receivers, level columns, accumulators, intercoolers, suction lines, oil lines, and liquid lines. SEE-LEVEL™ has a large diameter reflex lens for easy viewing. Frost shield length is suitable for temperatures down to -60oF (-50°C). Standard housing can be welded (fillet weld) into a 1 1/2" diameter opening or 1 1/2" socket weld fitting, or butt welded to a 1 1/2" pipe (Schedule 80). The scarfed (saddle milled) housing is available for simplified welding over a 1.5" (38 mm) hole, onto 2 1/2", 3", or 4" pipe, such as for level columns or liquid lines.
