In modern pharmaceutical manufacturing and sanitary food processing, implementing high-precision inline tracking for micro-dosing systems often introduces prohibitive electrical costs and complex cabinet cable wiring. The Endress+Hauser Promag H 200 Flowmeter is a highly specialized, industrial Electromagnetic Flowmeter engineered specifically to measure the smallest flow quantities with maximum plant efficiency. Operating on genuine loop-powered two-wire technology, this inline magnetic sensor seamlessly integrates into existing automation architectures without requiring standalone power infrastructure. Equipped with a high-purity PFA liner and a robust stainless steel housing, it provides safe volumetric monitoring for ultra-low velocity conductive mediums under rigorous CIP/SIP sterilization routines.
The following technical table provides the verified engineering parameters and material options defining the Promag H 200 two-wire fluid measurement platform:

| Hazardous Area Security | Global ATEX and IECEx explosion-proof certifications |
Unlike traditional four-wire inline magmeters that demand separate power and signal lines, the advanced two-wire design draws operating current directly from the 4-20mA loop. This significantly cuts overall hardware procurement budgets, minimizes system integration complexity, and reduces physical space demands in crowded junction panels via a dedicated separate connection compartment.
Preventing chemical contamination and structural degradation is mandatory in cleanroom processes. The PFA liner, combined with variable electrode options like Tantalum or Platinum, delivers extreme resistance to aggressive chemicals and thermal shocks during recurring CIP/SIP cycles, maintaining strict compliance with international sanitary safety guidelines.
To optimize plant availability and meet rigid ISO auditing requirements, the device runs 24/7 background self-testing on structural variables including coil integrity, amplifier stability, and electrode condition. Automated verification reporting is executed entirely within the active process loop, avoiding unnecessary operational shutdowns or validation delays.
Developed strictly to IEC 61508 standards, the transmitter architecture is officially certified for use in safety-instrumented networks up to SIL 2. Backed by universal ATEX and IECEx hazardous area stamps, it guarantees secure, predictable performance inside explosive processing zones.
Field technicians can safely configure or troubleshoot the device without exposing the internal electronics to harsh external elements. The integrated 4-line backlit display features advanced optical touch sensors, enabling seamless field parameter modification directly through the protective viewing glass.
In ultra-clean automated process systems, independent inline flow tracking must feed into wider multi-variable loops. To fully safeguard your sanitary installations from dangerous fluid pressure transients or storage vessel overflow, feed your real-time volumetric signals alongside our heavy-duty Pressure Transmitters and precision-grade Level Meters to form a responsive control grid.
