KROHNE OPTIFLUX 2300 Electromagnetic Flowmeter
Overview: The Widest Diameter Range for Demanding Water Applications
The KROHNE OPTIFLUX 2300 is an electromagnetic flowmeter (EMF) engineered for all demanding water and wastewater applications, particularly suited where high accuracy and extensive diagnostics are required. The OPTIFLUX 2300 offers the widest diameter range available in the market, DN25 to DN3000 (1 to 120 inch), and complies with custody transfer requirements per MID MI-001 and OIML R49, making it an effective alternative to mechanical water meters even in custody transfer measurement of potable water.
As an authorized supplier of KROHNE flow instrumentation, Seven Star LLC sources and supplies the OPTIFLUX 2300 electromagnetic flowmeter to water authorities, wastewater treatment plants, and industrial facilities across Oman and the wider GCC. Because custody transfer applications carry strict regulatory and installation requirements, Seven Star LLC helps engineering teams confirm the correct OPTIFLUX 2300 configuration and approvals for their specific project.
Measurement Principle
The OPTIFLUX 2300 measures flow based on Faraday law of electromagnetic induction: as electrically conductive water flows through the sensor magnetic field, electrodes detect a voltage proportional to flow velocity. What distinguishes the OPTIFLUX 2300 for custody transfer applications is its ability to achieve OIML R49 accuracy class 1 without requiring inlet or outlet straight-pipe runs (0D/0D installation), a significant installation advantage over flowmeters that demand upstream and downstream straight pipe lengths to achieve rated accuracy, particularly valuable in retrofit or space-constrained metering chamber installations.
A patented virtual reference option allows the OPTIFLUX 2300 to operate in a measuring mode even without additional grounding rings, delivering substantial cost savings in both installation labor and procurement of grounding hardware. Bi-directional flow measurement over a wide dynamic range (turndown ratio up to 1000:1) supports applications where flow direction may reverse or where a wide range of flow rates must be captured accurately by a single meter.
Engineering Design of the OPTIFLUX 2300
The OPTIFLUX 2300 achieves a standard measurement accuracy of plus or minus 0.2% or plus or minus 1 mm/s of measured value, with flange connections from DN25 to DN3000 rated up to PN40 / ASME Class 300, and digital communication options including 3x 4-20 mA, HART, Modbus, FOUNDATION Fieldbus, PROFIBUS PA/DP, and PROFINET. An IP68 / NEMA 6P rated version supports installation in measurement chambers subject to constant flooding, extending its applicability to submerged metering pit installations common in water utility infrastructure.
The flowmeter meets a wide range of potable water approvals including ACS, DVGW, NSF, TZW, KTW, and WRAS, reflecting its suitability for drinking water distribution metering across different international regulatory regimes. Full on-site verification without process interruption can be carried out using the KROHNE OPTICHECK service tool, allowing plant operators to confirm meter accuracy and health without removing the flowmeter from service.
Key Features
The KROHNE OPTIFLUX 2300 Electromagnetic Flowmeter delivers custody-transfer-grade accuracy for water and wastewater. Key characteristics include:

Industrial Applications
The OPTIFLUX 2300 is deployed across municipal water distribution networks, wastewater treatment plants, industrial water systems, and custody transfer metering stations for potable water. Its 0D/0D installation capability and wide diameter range make it particularly suited to retrofit metering projects and large-diameter distribution mains where achieving straight-pipe run requirements would otherwise be impractical or costly.
Seven Star LLC supports water authorities, wastewater treatment plants, and industrial facility operators across Oman, Muscat, Sohar, and the broader GCC region with sourcing of KROHNE OPTIFLUX 2300 electromagnetic flowmeters, helping projects achieve accurate, regulation-compliant water measurement.

Why Choose Seven Star LLC for KROHNE Custody Transfer Flowmeters
A custody transfer electromagnetic flowmeter carries real regulatory weight — the wrong approval class, liner material, or installation configuration can invalidate a metering point’s legal-for-trade status, which is a far more expensive mistake to catch after commissioning than before order placement. Seven Star LLC works directly with your project engineers to confirm the OPTIFLUX 2300’s approval package (MID, OIML R49), diameter, and liner material match your water authority or utility’s actual requirements, drawing on our authorized KROHNE partnership across Oman and the wider GCC. We also help coordinate on-site verification planning using KROHNE’s OPTICHECK tooling and support water utility and wastewater projects in Muscat, Sohar, and Salalah with documentation packages suited to regulatory submission.
