E+H 55S Proline Promag 55S electromagnetic flowmeter
$1,350.00
The Endress+Hauser Proline Promag 55S is a high-performance electromagnetic flowmeter designed for abrasive, inhomogeneous and high-solids-content liquids. It delivers reliable flow measurement even in challenging environments such as slurry, pulp or wastewater applications.
This flowmeter features a robust sensor design with optimized liners and electrodes. In addition, it can measure solids content alongside flow, which makes it highly valuable in demanding industrial processes.
Typical applications include mining slurry, sewage treatment, pulp and paper production, and metal processing industries.
Not Recommended For:
• Non-conductive liquids such as oil or gas
• Clean, low-solids applications where simpler models are sufficient
Selection Notes
• Confirm that the medium is conductive and contains solids, as this model is optimized for such conditions
• Verify the flow range, typically from 0.06 dm³/min to 600 m³/h
• Choose the correct liner material (e.g., polyurethane, rubber, PTFE) based on abrasion and chemical resistance
• Check the process temperature, which can reach up to 180 °C depending on configuration
• In addition, ensure the pressure rating (up to PN40 / Class 300) matches your system requirements
Why Choose the Promag 55S
• Designed for Abrasive and High-Solids Media
This model is specifically built for slurry and solids-laden liquids. Therefore, it performs reliably where standard flowmeters fail.
• Integrated Solids Content Measurement
The transmitter can calculate solids concentration in addition to flow. As a result, process monitoring becomes more efficient.
• Excellent Durability with Specialized Liners
A wide range of liner materials improves resistance to wear and corrosion. Consequently, service life is extended in harsh environments.
• Stable Measurement Independent of Process Variables
The electromagnetic principle is unaffected by density, viscosity or pressure. Therefore, measurement remains stable under varying conditions.
• Maintenance-Free Operation
There are no moving parts inside the sensor. This design reduces maintenance and minimizes downtime.
• Advanced Communication and Diagnostics
It supports HART, PROFIBUS PA/DP and FOUNDATION Fieldbus. In addition, built-in diagnostics improve operational safety.
