Key Challenges & Solutions

1. High-Flow Measurement in Cryogenic Environments

• Challenge: Liquid nitrogen at -195°C cryogenic temperatures presents challenges for traditional flow meters in high-flow conditions (5-24m³/h), including material embrittlement and signal drift, leading to measurement inaccuracies.
• Solution: Utilizing hydrogen-embrittlement-resistant materials and optimized sensor algorithms to ensure stable operation under extreme low-temperature conditions, enabling high-precision measurement across 5-24m³/h high-flow ranges.

2. Stable Performance in Cryogenic Low-Pressure Conditions

• Challenge: The combination of ≤4MPa low pressure and -195°C cryogenic conditions places extreme demands on the flow meter's sealing and structural integrity.
• Solution: Specifically designed for cryogenic low-pressure applications, ensuring long-term stable operation under low-temperature conditions.

3. Accurate Measurement Despite Phase Changes

• Challenge: Liquid nitrogen is prone to vaporization, with significant density changes during phase transition that challenge traditional volumetric flow meters.
• Solution: The Coriolis principle directly measures mass flow, unaffected by media phase changes or density variations, ensuring stable and reliable output.

4. Rapid Installation and System Integration

• Challenge: Cryogenic systems require excellent insulation and quick installation to minimize cold loss.
• Solution: Equipped with DN50 matching flanges for easy installation, supporting rapid integration into existing cryogenic systems.
