The Flexim FLUXUS F831 is a dual channel ultrasonic clamp-on flow meter for bi-directional flow measurement of liquids in hazardous areas (ATEX, IECEx Zone 1 and FM Class I, Div. 1 approved). With its explosion proof housing, optional intrinsically safe inputs and outputs and the corrosion resistant transducers residing outside the pipe wall, the FLUXUS F831 series is perfectly suited for every demanding industrial application in and out of the oil field and the chemical industry. The connection and electronics compartments of the FLUXUS F831 are hermetically sealed and the FLUXUS F831 comes with carefully matched and temperature compensated transducers (fully ANSI / ASME MFC 5M compliant) providing unmatched zero-point stability.
