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.
