Introduction
The Proline Promag H 200 is a loop-powered electromagnetic flow meter purpose-built for the smallest flow quantities, ideal for chemical, life sciences and hygienic applications. With PFA lining, stainless steel housing, and Heartbeat Technology, it delivers accurate, maintenance-free flow measurement while ensuring compliance with global safety standards.
Key advantages
1. Loop-Powered Operation: Eliminates need for external power, enabling seamless integration into existing 4-20mA infrastructure with no additional wiring.
2. Ultra-Small Flow Capability: Measures volumes as low as 0.06 dm³/min with ±0.5% accuracy, ideal for micro-flow applications in pharma and chemical industries.
3. Full Hygienic & Corrosion Resistance: Features PFA liner and 316L/C22/tantalum electrodes, supporting temperatures up to 150°C and aggressive process fluids.
4. Maintenance-Free & Robust Design: No moving parts, IP69 ingress protection, and dual-compartment housing ensure long-term reliability with zero routine upkeep.
5. Heartbeat Technology for Safety: Integrated verification provides continuous self-diagnostics and traceability, meeting SIL and ISO 9001 requirements for process safety.
