$900.00
The Endress+Hauser Proline Promag H 200 5H2B Electromagnetic Flowmeter is designed for high-precision measurement of small flow rates in chemical and life sciences industries. It features genuine loop-powered technology, enabling cost-effective integration without the need for additional power supply.
Using the electromagnetic measuring principle, it provides accurate bidirectional flow measurement of conductive liquids, independent of pressure, temperature, density, and viscosity. This ensures stable performance even in demanding process conditions.
The intrinsically safe design makes it suitable for hazardous areas, while Heartbeat Technology ensures continuous process reliability and verification.
Typical applications include dosing, small-volume measurement, pharmaceutical processes, and chemical injection systems.
Not Recommended For:
• Non-conductive liquids such as oils or hydrocarbons
• Applications with large solids or strong abrasion
Selection Notes
• Confirm the fluid is electrically conductive, required for electromagnetic measurement
• Verify small flow rate range, especially for dosing or micro-flow applications (down to very low flow rates)
• Select appropriate nominal diameter (DN 2–25) for small pipelines
• Choose required communication protocol, such as HART, PROFIBUS PA, or FOUNDATION Fieldbus
• Ensure hazardous area requirements (Ex ia) if installed in explosive environments
• Confirm hygienic or chemical compatibility, including PFA liner and electrode materials
