Flexim FLUXUS Flow Meter for LNG and Cryogenic Fluids

With its huge measurement range, the Flexim FLUXUS Cryo non-intrusive ultrasonic flow meter is ideally suited to cover the highest flow rates of loading / off-loading processes, as well as very low flow rates when lines start or stop.

Capable of performing in various LNG and other cryogenic applications at temperatures down to -200 °C (-328 °F): from 3-inch lines in peak shaving plants to 36-inch pipes for tanker off-loading to storage tanks, these non-intrusive ultrasonic flow meters provide the ideal solution for all cases where reliable and trouble-free flow measurement of cryogenic fluids is required.

Features

Highly reliable:
Maintenance-free. No moving or vibrating parts.
Dual-beam redundant measurements.
Operationally safe: no gaskets, no leakage points.
Economical: no pipework modification necessary.
One-person-installation without the need for lifting gear.
No pressure loss - no chance for flashing.
Advantages in retrofit applications:
No pipework necessary.
No lifting gear required - independent of pipe size.
FLUXUS Cryo can be mounted at limited space conditions, e.g. at FLNG loading arms.
Installation is done within a few hours when the pipe is not cooled down.
The measuring system is fully integrated into the insulation.
Advantages in new plants:
Highly cost-effective - only standard piping needs to be planned - FLUXUS Cryo fits.
Late design changes are not a problem! One equipment type fits many pipe sizes.
No pressure-loss and thus no energy loss.
No risk of flashing.
Significantly reduced CAPEX, especially for large diameters.
Global installation and support by Flexim.
