The OPTIFLUX 4100 is an electromagnetic flowmeter (EMF) for a wide range of standard process applications with aggressive and abrasive liquids. It enables reliable flow measurement even under harsh process conditions with temperatures up to +180°C / +356°F, low conductivity (≥5 µS/cm) and solid content (up to 10%). This makes the flowmeter particularly suitable for applications involving corrosive chemicals, sewage and drilling mud or mining sludge. Installation in measurement chambers subject to (constant) flooding is also possible using the optional IP68 / NEMA 6P rated version.
