Cryogenic Coriolis Mass Flow Meter for Liquid Oxygen and LNG
The SH-CM Cryogenic Coriolis Mass Flow Meter is engineered for ultra-low temperature applications down to -200°C, including liquid oxygen (LOX), liquid nitrogen (LN2), LNG, and liquid hydrogen. Featuring an extended neck design to isolate electronics from cold, austenitic stainless steel construction, and metal seals for leak prevention, it delivers accurate mass flow and density measurement in the harshest cryogenic environments. Certified with ATEX for hazardous zones.
Key Selling Points
- Ultra-Low Temperature Capability: Measures fluids down to -200°C – ideal for liquid oxygen at -183°C, LNG, and liquid hydrogen.
- Extended Neck Thermal Isolation: Protects electronics from extreme cold – ensures stable electronics performance and long service life.
- Accurate Mass Flow & Density: Provides direct mass flow measurement with accuracy up to 0.2% – eliminates separate density meters.
- ATEX Certified for Zone 2: Safe for hazardous cryogenic gas applications – certified to IEC 60079 standards.
- Cost-Effective Alternative: Priced at approximately one-fifth of leading brands like Micro Motion – delivers high-end performance at factory-direct pricing.
