Do you need to measure really low flows? Turn to FLUXUS XLF
FLUXUS XLF is FLEXIM‘s non-invasive metering system for the reproducible and long term reliable measurement of extremely low flow rates down to 1 gal/h and below on line sizes ranging from 0.4 inch to 2 inches independent of the pipe wall thickness. As the flow sensors are mounted externally, there is no process interruption for installation.
Moreover, due their NEMA 6P rating, ATEX / IECEx Zone 1 / 2 as well as FM Class I, Div. 1 / 2 approval and being completely made out of stainless steel (316L / 1.4404 grade), the measurement system is highly rugged and withstands even the harshest and most corrosive environmental conditions.
FLEXIM is the much more cost-effective and safer alternative for measuring extremely low flows of any liquid
The FLUXUS XLF is applicable on all pipe materials and wall thicknesses as well as independent of operating pressures.
In comparison to wetted instrumentation, the system does not suffer from mechanical stress or wear and tear by the medium and is thus not only much more cost efficient, but also offers significantely higher operational safety as the risk of leaks can completely be eliminated.
Its high accuracy and repeatability at extremely low flow velocities is achieved by carefully matched and temperature compensated transducers (acc. to ANSI/ASME MFC 5.1-2011), highly sensitive electronics and sophisticated internal signal processing as well as a highly precise and traceable wet flow calibration (according to NIST standards) at FLEXIM‘s low flow calibration facility.
Tests with water under stable temperature conditions yield the following results:
For thin-wall (0.02-0.04”) tubing, after zeroing, the meter will consistently provide better than 5% volume accumulation uncertainty (based on flowing for at least one minute) for the flow rates listed in the table below, using an 8-pass installation with Q transducers.
This performance will be observed for 95% of batches (two-sigma).
