OPTIFLUX 6400

The OPTIFLUX 6400 is a precision electromagnetic flowmeter engineered for demanding hygienic applications requiring custody transfer compliance. Available in compact (C) and field-mounted (F) configurations, it delivers accurate liquid flow measurement across process temperatures from -40°C to +140°C and pressures up to 40 bar. Integrated Bluetooth® and HART® connectivity enable wireless on-site verification and remote diagnostics, while comprehensive certifications—including FDA, 3A, EHEDG, ATEX, and major custody transfer standards (AGA, API, OIML)—ensure regulatory compliance across pharmaceutical, food, and industrial sectors.
