Endress+Hauser Flowmeter 50E/53E/55S/5BH E+H Promag Series Electromagnetic Flowmeter

Overview of the Proline Promag 55S

The Proline Promag 55S is a high-performance electromagnetic flowmeter designed to precisely measure liquids—even those that are abrasive, inhomogeneous, or contain solids. It’s a robust, reliable solution ideal for demanding industrial environments.

Key Features & Specifications

1. Applications & Fluid Types

• Suited for measuring bidirectional flow of:
• Liquids with at least 5 µS/cm conductivity
• Fluids with solid contents (e.g., pulp, slurries up to 15 Vol-%)
• Challenging media like fruit mashes, concentrates, soups, slurries (e.g., ore or mortar), thick wastewater, and chemically inhomogeneous fluids
• Excellent for sectors such as pulp & paper, wastewater treatment, mining, and food production.

2. Performance & Range

• Flow range: up to ~9,600 m³/h (≈42,267 gal/min)
• Process conditions: Temperatures from –40 °C to +180 °C; pressure up to 40 bar (580 psi)
• Diameter: DN 15…600 (½″ to 24″)
• Accuracy: typically ±0.2%

3. Sensor Design & Materials

• Built with industry-specific liners: natural rubber, hard rubber, polyurethane, PTFE, PFA
• Multiple electrode options: flat, bullet-nose, neck, bow, brush shapes; materials include 1.4435/304L, Alloy C-22, tantalum, platinum, duplex steel, tungsten carbide, titanium
• Designed for abrasion resistance and longevity—especially important when handling abrasive slurries or solid-laden fluids.

4. Advanced Transmitter & Diagnostics

• Modular transmitter architecture enhances efficiency and configurability
• Features include:
• Electrode cleaning routines
• Advanced diagnostics
• Mass flow and solids-content calculation
• Stability boosted by unique signal processing technology

5. Integration & Communication

• Compatible with common industrial protocols: HART, PROFIBUS DP/PA, FOUNDATION Fieldbus
• Expands connectivity for modern automation and smart monitoring.

6. Additional Advantages

• Virtually unaffected by variations in pressure, density, temperature, or viscosity
• No moving parts—i.e., low maintenance and high reliability
• Built-in self-diagnostics and recovery capabilities
• Offers integrated solids-content measurement—essential for process control in slurry environments
• Features like touch-controlled backlit display and switch outputs (two) aid usability
