Direct answer

Yes. LibertyCES has documented Sight Glass in Chemical Processing applications, including Richter PSG, Richter TSG and Richter SGS. The right model depends on the fluid, concentration, temperature, flow and duty cycle, so send James your process data for a free spec review before final selection.

Install / Failure Note

SGS trades a lower pressure rating (6 bar vs. 16 bar) and a narrower temperature range for a cavity-free design that doubles as a level indicator — a real functional tradeoff to flag before specifying it for a high-pressure in-line sight-check application it isn't rated for.

A sight glass is a genuinely distinct equipment category for process observation, not a powered instrument, but the material and pressure choice still has to match the process — Richter's PSG and TSG both hold 16 bar at up to 360°F for in-line process sight-checking, while the SGS trades pressure and temperature range for a cavity-free design that can double as a level indicator.
