LNG Coriolis Mass Flow Meter | Cryogenic Precision

Core Operational Challenges Addressed

• Compared to traditional gas flow meters (such as turbine, vortex, and differential pressure types), the advantages of Coriolis flow meters are decisive. The LNG return gas flow can fluctuate significantly, requiring accurate measurement from small venting flows to large recovery flows. The small DN8 diameter is well-suited for lower return gas flows. Flow meters like turbine types cannot start or have significant errors at low flow rates.
• The Coriolis principle is sensitive to the mass of the fluid, not its flow velocity. Therefore, it maintains excellent measurement performance even at extremely low flow rates, with an extremely wide range ratio (up to 100:1), capable of fully covering the entire flow range that may occur during the gas return process.
• Gas flow meters (such as orifice plates and vortex types) have demanding installation requirements, needing long straight pipe sections upstream and downstream to ensure fully developed flow for accurate measurement. This is often difficult to satisfy when on-site space is limited.
• The Coriolis mass flow meter's measurement principle is largely unaffected by flow velocity distribution, thus requiring minimal straight pipe sections upstream and downstream. This greatly simplifies on-site installation, saves space, and reduces measurement errors caused by improper installation.
