Icon Process Controls
"Corrosion-Free Instrumentation Equipment" — analytical, flow, level, pressure, and leak detection instrumentation for chemical process service.
What LibertyCES specifies from Icon Process Controls
P14 Series pH sensors split by named process condition — including a real quantified hydrofluoric acid concentration threshold (P14H under 4000 ppm, P14F over).
Zirconium Ceramic and ETFE Tefzel wetted parts, PFA Teflon construction to 248°F, and Kalrez O-ring options down to 0.01 GPM for dosing applications.
Fully-welded 316SS 300S for zero-elastomer chemical exposure; MLR-70 guided-wave radar explicitly named for liquid chemical storage and chemical sumps.
Direct-diaphragm and gauge-guard pressure gauges, plus LDS-YN electrostatic leak sensors for double-wall tank interstitial space and secondary containment.
Frequently Asked Questions
What pH sensor is rated for hydrofluoric acid service?
Icon's P14 Series splits by HF concentration: the P14H model is rated for HF Acid under 4000 ppm, and the P14F model is rated for HF Acid over 4000 ppm — a real, quantified concentration threshold for HF-specific pH instrumentation.
What is the difference between a direct-diaphragm and gauge-guard pressure gauge?
A direct-diaphragm gauge bonds a corrosion-resistant PTFE diaphragm directly into a PVC/PP/PVDF body (±0.75% accuracy). A gauge-guard gauge isolates a standard, cheaper gauge movement behind a flexible diaphragm so it never contacts the process fluid, at a slight accuracy trade-off (±1.5%).
What sensor is designed for double-wall tank leak detection?
The LDS-YN electrostatic leak sensor is explicitly engineered for the interstitial area between double wall tanks, tank retention dikes, and secondary containment sumps, pairing with the PA223 alarm.
