OPTIFLUX 4300C Krohne Electromagnetic Flow Metre For Advanced Process And Ct Applications

The OPTIFLUX 4300 is an electromagnetic flowmeter (EMF) for advanced process applications with aggressive liquids or abrasive media. The high-end flowmeter is particularly suitable for critical applications requiring high accuracy and many diagnostic functions. It enables reliable measurement even under very harsh process conditions with temperatures up to +180°C / +356°F, low conductivities (≥1 µS/cm), high solid contents (up to 70%) and high pressures (up to 1500 bar / 21751 psi). For custody transfer applications, the OPTIFLUX 4300 has a wide range of certifications including OIML R49 and R117 or MI-001 and MI-005. It can also be used for flow measurement in district heating networks requiring MI-004 approval.

The OPTIFLUX 4300 is available in a wide diameter range up to DN3000 / 120". Its patented virtual reference option allows for a very cost-saving measuring mode without additional grounding rings – particularly when it comes to large diameters. Installation in measurement chambers subject to (constant) flooding is possible with the IP68 / NEMA 6P rated version. The meter is approved for use in hazardous areas and offers various digital communication options. A full on-site verification of the OPTIFLUX 4300 without process interruption can be carried out using the OPTICHECK service tool.
