When viewing the SG1 Sight Glass, refrigerant liquid levels rise in the viewing area of the reflex lens, the color of the lens will turn dark. As the level decreases the color of the lens lightens. Basketball playbook 011 serial key. The housing is made from ASME SA36 and meets material requirements of ASME for direct welding to vessel. The reflex lens is made from a clear boro. Sight Glass/ Moisture Indicator. Often in commercial HVAC and refrigeration, you will either find or install sight glass/moisture indicators. The sight glass portion is simple; it's just there to show if the liquid line has a full line of liquid or if it has bubbles, which shows it's a liquid/vapor mix. A clear sight glass on a running system. The Refrigerating Specialties liquid level sight glass SG1 provides a clear indication of liquid levels in industrial and commercial refrigeration systems.

Sight Glass And Moisture Indicator
A combination sight glass and moisture indicator is essential for easy field maintenance on any system, and is required on any field installed system unless some other means of checking the refrigerant charge is provided.
A sight glass in a convenient means of determining the refrigerant charge, showing bubbles when there is insufficient charge, and a solid clear glass when there is sufficient charge. however, the operator should bear in mind that under some circumstances even when the receiver outlet has a liquid seal, bubbles or flash gas may show in the sight glass. This may be due to a restriction or excessive presure drop in the receiver outlet valve, a partially plugged drier or strainer, or other restriction in the liquid line ahead of the sight glass. If the expansion valve feed is erratic or surging, the increased flow when the expansion valve is wide open can create sufficient pressure drop to cause flashing at the receiver outlet.
