In 2026, water treatment plants face increasing process disturbances. The OPTIFLUX 2400 addresses this through its proprietary Multi-Phase Operation (MPO) technology. Unlike standard electromagnetic flowmeters (EMF) that fail during gas entrainment or high solid content, the OPTIFLUX 2400 maintains stable and repeatable readings even in the presence of:
Entrained gas bubbles.
High percentage of abrasive solids/slurries.
Electromagnetic interference in heavy industrial zones.
For high-precision applications requiring mass flow measurement under similar gas-entrained conditions, consider the [KROHNE OPTIMASS Coriolis Flowmeter], which features Entrained Gas Management (EGM™) technology.
The OPTIFLUX 2400 is more than a flowmeter; it is a diagnostic tool. With integrated conductivity measurement as standard, it provides:
Real-time water quality tracking: Fast response times for detecting chemical changes or contamination.
Empty pipe detection: Prevents pump dry-run and protects downstream assets.
Cost savings: Eliminates the need for a separate conductivity sensor, reducing installation complexity and procurement costs.
The traditional days of opening converter housings in confined spaces are over. The OPTIFLUX 2400 leverages Bluetooth® connectivity and the OPTICHECK Flow Mobile App to simplify lifecycle management.
On-site Verification: Generate a full device status report wirelessly without interrupting the process.
NAMUR NE 107 Compliance: Color-coded backlit displays provide immediate status alerts (Error, Maintenance Required, Out of Specification).
EcoMode: Reduce power consumption for sustainable operations without sacrificing measurement accuracy ($\pm 0.2\%$).

Choosing a flowmeter for wastewater requires balancing chemistry and physics.
For Potable Water: Select the PP liner with NSF/WRAS approvals.
For Sewage & Sludge: The Hard Rubber liner is superior for its abrasion resistance.
For Burial Installations: Opt for the IP68/NEMA 6P sensor version to ensure longevity in continuous flooding conditions.
In smart water networks, synchronous pressure monitoring is essential. We recommend integrating the [Rosemount 3051S Pressure Transmitter] alongside your OPTIFLUX 2400 for a complete pipeline integrity solution.
Virtual Reference: Utilize KROHNE’s Virtual Reference grounding. This eliminates the need for expensive grounding rings in large-diameter pipes, significantly reducing the bill of materials (BOM).
Pipe Orientation: Always ensure the meter is installed in a line that is completely full. Vertical installation with upward flow is ideal for sludge and high-solid media to prevent sediment buildup.
Straight Runs: While EMFs are robust, maintain $5D$ upstream and $2D$ downstream for maximum precision.
Utilize the Real-time Clock to log events. When an alarm occurs, use the OPTICHECK DTM or mobile app to analyze the diagnostic buffer. Most issues, such as electrode coating or gas bubbles, are identified by the internal 80+ diagnostics, allowing for targeted cleaning rather than blind replacements.
Q: What is MPO (Multi-Phase Operation) technology, and how does it handle sludge measurement? A: MPO is a proprietary KROHNE signal processing algorithm. In wastewater applications where gas bubbles or high solid concentrations (sludge/slurries) cause standard electromagnetic flowmeters to have unstable readings, MPO filters out the noise. It maintains continuous measurement and delivers repeatable flow and conductivity data even during these major process disturbances.
Q: How much can I save by using the "Virtual Reference" grounding method? A: Traditional EMFs require expensive grounding rings when installed in plastic or lined pipes. KROHNE’s Virtual Reference technology allows the converter to detect the electrode potential directly, eliminating the need for grounding rings. For large-diameter pipes (above DN300), this typically saves 15% to 30% in procurement and installation costs.
Q: Can I verify the flowmeter status without interrupting the process or opening the housing? A: Yes. The OPTIFLUX 2400 features integrated Bluetooth® connectivity. Using the KROHNE OPTICHECK Flow Mobile app, you can wirelessly parameterize, monitor real-time data, and perform a full on-site verification. A professional verification report can be generated with a single click, which is ideal for audit compliance without process downtime.
Q: Is the OPTIFLUX 2400 suitable for drinking water applications? A: Absolutely. The OPTIFLUX 2400 comes with a wide range of international potable water approvals, including NSF, WRAS, DVGW, TZW, and KTW. The PP (Polypropylene) liner is specifically designed to meet stringent global health and safety standards for drinking water distribution.
