Certifications: SIL 3 safety (IEC 61508), OIML R85, and API 3.1B compliance 2.
Technical Parameters:
Temperature Range: -200°C to +200°C
Pressure Range: 0.2–6 bar
Measurement Span: Up to 36 m
Materials: 316L stainless steel, Alloy C276, PTFE seals 2.
Applications:
Custody transfer of crude oil, chemicals, and refined products.
Inventory control in tank farms requiring legal metrology certification (e.g., NMi, PTB) 2.
No Direct Link to "NMS-80207": The search results do not explicitly reference a combined model "NMS-80207". The bearing 80207 and the level gauge NMS80 are unrelated products.
