Krohne OPTIFLUX 4100 Electromagnetic Flowmeter

The Krohne OPTIFLUX 4100 is an electromagnetic flowmeter (EMF) for a wide range of standard process applications with affressive and abrasive liquids. The OPTIFLUX 3100 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 OPTIFLUX 4100 suitable for applications that invlolve corrosive chemicals, sewage and drilling mud or mining sludge. The OPTIFLUX 4100 is available in an optional IP68/NEMA6P rated version, making installation in measurement chambers that are subject to (constant) flooding possible.

Unlike the OPTIFLUX 4050, the OPTIFLUX 4100 features higher accuracy. It comes with a selection of chemically resistant liners and electrodes. Due to its full bore design without moving or intruding parts, there is no pressure loss and no maintenance required. A full on-site verification of the OPTIFLUX 4100 without process interruption can be carried out using the OPTICHECK service tool.
