SGS is the only one of the three rated for both a lower pressure (6 bar vs 16 bar) AND usable as a level indicator via its cavity-free design — a functional differentiator the vendor calls out explicitly. Moderate because level indication is a stated capability rather than a separate SKU. Quoting caveat: SGS also has the narrowest temperature range of the three, so the capability comes with a real thermal tradeoff.

SGS carries the narrowest temperature range and lowest pressure rating of Richter's three sight-glass models — a real thermal/pressure tradeoff that comes with its level-indicator capability, worth confirming against the tank farm's actual operating pressure before specifying it over the PSG or TSG.
A chemical storage tank farm sight glass used for level visualization has a different job than an in-line process sight-check — Richter's SGS is the one model in the line engineered for it, with a cavity-free design that functions as a level indicator, but that capability comes at a real cost: the narrowest temperature range and lowest pressure rating (6 bar) of the three sight-glass models.

FAQ
Is Sight Glass used in Chemical Storage & Tank Farm?
SGS is the only one of the three rated for both a lower pressure (6 bar vs 16 bar) AND usable as a level indicator via its cavity-free design — a functional differentiator the vendor calls out explicitly. Moderate because level indication is a stated capability rather than a separate SKU. Quoting caveat: SGS also has the narrowest temperature range of the three, so the capability comes with a real thermal tradeoff. This is moderate evidence.
What products are specified for Sight Glass in Chemical Storage & Tank Farm?
Documented examples include Richter SGS / SGS/F / SGS/F-L (cavity-free design option, usable as a level indicator, DN15-DN100, 6 bar, -60°C to +150°C, cylindrical body viewable from all sides) — confirm current specifications with the manufacturer before final selection.
