The OPTIFLUX 5000 is a high-accuracy electromagnetic flowmeter with a high-tech zirconium oxide ceramic measuring tube, available in a flanged version and a compact sandwich (wafer) version. The ceramic tube resists corrosive and abrasive fluids, is fully vacuum-resistant and immune to temperature shock, and gives exceptional long-term stability, which is why metrology institutes use it as a master meter. It measures flow velocity, volume flow, mass flow and electrical conductivity, and pairs with IFC 050, 100, 300 or 400 converters in compact or remote form.
