Sight Glass

Where LibertyCES specs Sight Glass
Chemical Processing
Strong evidenceGenuinely new equipment category — no sight glass exists elsewhere in the corpus. Shared: housing EN-JS 1049, flanges to ISO 7005-2 Type B or ASME B16.5 Class 150 raised face, EU PED 2014/68/EU and TA-Luft. Assigned to Sensing & Control because the function is process observation; a Piping & Fittings assignment is equally arguable (flanged in-line body, no powered output) — flagged as a taxonomy judgment, not a data finding. Selection rule: PSG or TSG for in-line process sight-checking, SGS for tank level visualization.
Chemical Storage & Tank Farm
Moderate evidenceSGS 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.
Chemical compatibility
No documented chemical-compatibility record yet for this category — a spec review is the right next step before specifying against a specific chemical.

What is a real-world application of Sight Glass in Chemical Processing?
Genuinely new equipment category — no sight glass exists elsewhere in the corpus. Shared: housing EN-JS 1049, flanges to ISO 7005-2 Type B or ASME B16.5 Class 150 raised face, EU PED 2014/68/EU and TA-Luft. Assigned to Sensing & Control because the function is process observation; a Piping & Fittings assignment is equally arguable (flanged in-line body, no powered output) — flagged as a taxonomy judgment, not a data finding. Selection rule: PSG or TSG for in-line process sight-checking, SGS for tank level visualization. — examples include Richter PSG (standard flanged, DN25-DN150, 16 bar, -60°C to +180°C / -75°F to +360°F, DIN 3237 part 2, integrated drip lip, individually exchangeable cover flanges, borosilicate panes to DIN 7080; PSG/F in PFA, PSG/F-L antistatic PFA), Richter TSG (standard flanged, DN25-DN80, 16 bar, -60°C to +180°C; TSG/F, TSG/F-L), Richter SGS (cylindrical, DN15-DN100, 6 bar, -60°C to +150°C, viewing from all sides, cavity-free design option; SGS/F, SGS/F-L). This is well-documented in LibertyCES's field data.

Fluid, chemistry, concentration, temperature, flow, pressure, line size, and current equipment — that's what a real spec review needs to start.
