What Matters in Dosing and Measurement
Four factors that are crucial when selecting a dosing and measurement solution.
Measurement Principle
- Oval impeller (FMO) for high-viscosity fluids up to 500,000 mPas
- Wobble disc (FMC) for slightly contaminated media; can be mounted in any orientation
- Turbine impeller (FMT) for mobile small-volume measurement on JUNIORFLUX/COMBIFLUX
Accuracy & Legal Metrology
- ± 0.5% repeatability in calibrated FMC/FMO-FLUXTRONIC® systems
- Calibration-accurate weighing technology (FPackV-compliant) with FLUX FILL GT
- MID 2014/32/EU and the German Measurement Act (MessEG) for sales filling subject to calibration requirements
Media Compatibility
- Materials: PP, ETFE, PVDF, stainless steel, and aluminum, depending on the medium
- Fluid temperatures up to 120 °C (FMO), operating pressures up to 200 bar
- Explosion protection for flammable media (FMC, FMO S/S: II 2G Ex h IIB T4 Gb)
Integration & Control
- FLUXTRONIC® with manual and automatic (batch) modes at the push of a button
- Signal outputs to valves, actuator motors, or PLC
- Non-volatile memory, 4 PIN-protected security levels, wall mounting

Frequently Asked Questions About Filling
The FLUXTRONIC® control system with an FMC or FMO flow meter typically achieves a repeatability of ±0.5% when the system is calibrated. The actual accuracy depends on the medium, viscosity, flow rate, and switch amplifier configuration. For more stringent requirements (filling subject to calibration), the FLUX FILL GT with weighing technology compliant with FPackV is recommended.
Calibrated weighing technology in accordance with the Prepackaged Goods Regulation (FPackV) is required when the filled quantity is labeled for sale—that is, for prepackaged goods intended for the end consumer. The FLUX FILL GT operates using the overfill method with a calibration-accurate load cell and is designed for small and medium-sized batches.
Explosion-proof filling involves three levels: an ATEX-certified pump (materials, bearings, coupling), an ATEX-certified motor (compressed air or explosion-proof electric motor), and a grounding concept that includes antistatic hoses and equipotential bonding between the source and target containers. The zone classification (Zone 0/1/2) is determined by the system and dictates the selection of components.
Yes. Manual pump sets can be retrofitted with a flow meter (FMC or FMO), a switching amplifier, and a FLUXTRONIC® controller. The pump and motor are generally retained—only the outlet fitting is replaced with the FLUX filling unit (FAE).
The SAFETEC pump set is designed for sealed hazardous-material containers with CDS or QC couplings. It empties the containers while they remain sealed via an immersion tube—without spilling a drop and without personnel coming into contact with the contents. The self-priming MAGSON magnetic centrifugal pump operates with a hermetically sealed design.
