Condensate Monitoring
Type Approvals: EC approvalTÜV (Germany)
Low-level limiter of “high-integrity design”: level electrode NRG 16-50, level switch NRS 1-50, SIL 3
Separate high-level alarm of “high-integrity design”: level electrode NRG 16-51, level switch NRS 1-51, SIL 3
Level control with high-level alarm and remote water level indicator: level probe NRG 26-21, level controller NRR 2-52 and control valve V726
Water level gauge
Conductivity measurement with indicator, conductivity limit switch and continuous blowdown control: conductivity electrode LRGT 16-2, continuous blowdown controller LRR 1-52, continuous blowdown valve BAE
