Flexim FLUXUS F809 Flow Meter

Flow meter for hazardous areas

The FLUXUS F809 is FLEXIM’s dual channel ultrasonic clamp-on flow meter for bi-directional flow measurement of fluids in hazardous areas (ATEX, IECEx Zone 1 and FM Class I, Div. 1 approved).

With its flameproof housing and the corrosion resistant transducers mounted on the outside of the pipe wall, the FLUXUS F809 series is suited for almost every demanding industrial application. The connection and electronic compartment of the FLUXUS F809 is sealed, so that the measurement system provides maximum operational reliability and safety.

The FLUXUS F809 is rugged, reliable and precise. Thanks to its matched and temperature compensated transducers (fully ANSI / ASME MFC 5M compliant), the FLUXUS F809 offers an unparalleled zero point stability and precise bi-directional flow measurement of virtually any liquid media – ranging from crude oil to refined products and chemical media over an unlimited turndown range.
