Armored liquid level gages (sometimes called armored level sight glasses) are standard items for petrochemical refineries, chemical plants, and other installations. These gauges are essentially identical to gauges made by a number of companies such as Jerguson, Penberthy, Quest Tec, etc., in this product space, all of which are equivalent.
Model Q2 level gages are medium pressure units with up to 2000 PSI ratings, while Model Q3 gauges rate up to 4000 PSI. They are available with transparent and reflex (prismatic) gage glasses.
