Fully redundant dual four-path liquid ultrasonic flow meter for cryogenic LNG custody transfer and dynamic metering — two complete sets of 4-path electronics + transducers in one spool, providing the most rigorous redundancy in the industry for marine LNG transfer. Multi-plane interlocked British Gas meter geometry delivers ±0.15% factory-proven linearity and ±0.027% meter-factor uncertainty. Cryogenic-rated SST body and seals tolerate -162°C LNG. Full-bore design eliminates pressure drop and the risk of LNG flashing. Used in marine custody transfer (loading and unloading), fiscal metering, line balancing, allocation, and check metering on land-based LNG terminals. Same 3810 series electronics platform.
