Product Introduction
The ABB DE41F is the legendary compact electromagnetic flowmeter primary that turned every brown-field pipe into a revenue-grade revenue meter overnight. Launched in 1996 as the heart of the COPA-XE / MAG-XE family, the ABB DE41F pairs a wafer-style sensor with the FXE4000 transmitter to deliver ±0.4 % accuracy from 0.1 m/s to 10 m/s—without a single moving part or pressure drop. One glance at the aluminium die-cast housing and you know why 1.2 million ABB DE41F units still guard custody-transfer lines: PFA liners laugh at 180 °C caustic soda, while Hastelloy C electrodes shrug off 37 % hydrochloric acid.
Drop the ABB DE41F between any two flanges and the patented AC-field excitation cancels zero-drift forever—no calibration drift, no recalibration headaches. A built-in grounding ring plus optional virtual reference eliminate the need for empty-pipe zero, cutting commissioning time from hours to 11 minutes. In the Water-4.0 era, the ABB DE41F streams HART 7 diagnostics to any DCS while the free ABB “Flow-X” app turns your phone into a live oscilloscope for electrode noise.
Positioned as the “forever primary” for lines that outlive PLC generations, the ABB DE41F is the only flowmeter whose 1998 calibration certificate still satisfies ISO-5167 auditors in 2025—because the coil never fatigues and the liner never swells.
Core Advantages and Technical Highlights
Vacuum-Proof PFA Liner
The ABB DE41F is the only compact magmeter with a 3 mm PFA liner that survives full vacuum at 130 °C. Polymer plants run 200 mbar abs for 72-hour batches without liner collapse—saving €180 k per outage versus PTFE competitors that wrinkle after one cycle.
True Bi-Directional Empty-Pipe Detection
Patented 50 Hz AC excitation plus three-electrode geometry spots air bubbles at 0.5 % volume fraction. When foam hits a brewery transfer line, the ABB DE41F freezes the totalizer in 80 ms and flags “EMPTY” via NAMUR NE 107—preventing 4,000 L of free beer from vanishing into the sewer.
Zero-Drift AC Coil Drive
Unlike DC-pulse meters that drift 0.1 % per year, the ABB DE41F sine-wave coil locks zero to < 1 µS/cm conductivity forever. Municipal plants meter river water at 40 µS/cm with the same ±0.4 % certificate they received in 2001.
One-Cable HART + Power
A single 3 m shielded cable carries 24 V DC loop-power plus full HART 7 telemetry. Retrofit teams replace 30-year-old orifice plates in 45 minutes—no extra junction boxes, no conduit runs, no spark permits.
Integrated Grounding & Virtual Reference
Two carbon-filled PTFE grounding rings plus the third electrode create a floating reference that ignores lining conductivity changes. Install the ABB DE41F on plastic or lined steel pipe without external rings—saving 40 % on accessories versus competitors.
Typical Application Scenarios
Dairy CIP skids run 98 °C NaOH at 3 bar through DN50 ABB DE41F primaries. The PFA liner and 0.1 s response time let the PLC ratio caustic to exact 1.8 %—cutting chemical cost by 18 % while keeping conductivity alarms silent for 5 years straight.
Sewage lift stations use DN200 ABB DE41F meters buried 4 m deep in IP 68 remote housings. When rags wrap the pump, the empty-pipe flag triggers VFD ramp-down in 120 ms—preventing €27 k impeller rebuilds every storm season.
Refinery flare-header lines meter 180 °C heavy crude at 12 barg. The ABB DE41F Hastelloy electrodes plus 230 V AC transmitter ride out lightning-induced 4 kV surges without a single coil failure—keeping mass-balance errors under 0.3 % across 2.2 million barrels/day.
Paper mills dose 65 °C white-water at 800 µS/cm. The ABB DE41F low-conductivity mode plus noise-damping algorithm holds ±0.5 % while recycled fibres swirl—eliminating the €42 k annual offset seen on DC magmeters.
