Endress+Hauser Promass F 500 Coriolis Mass Flowmeter 8F5B

Introduction

The Endress+Hauser Promass F 500 (8F5B) is a high-performance Coriolis mass flowmeter engineered for custody transfer, precise batching and demanding process measurements in chemical, oil & gas, pharmaceutical, food & beverage and energy applications.

Using a single sensor, it captures mass flow, process density and fluid temperature at the same time — with no dependence on Reynolds number, medium conductivity, viscosity or upstream flow profile. The split transmitter design allows remote mounting in hard-to-reach or high-temperature locations, while Heartbeat Technology provides continuous, process-trusted diagnostics and audit-ready verification without interrupting operation.

Key Advantages

• Custody-transfer accuracy: Liquid mass flow accuracy reaches ±0.10% of reading standard, or ±0.05% with PremiumCal calibration; gas accuracy is ±0.25%, making it suitable for fiscal metering and high-value product transfer.
• No straight-pipe requirement: Full accuracy is maintained regardless of upstream or downstream fittings — no straight runs, no flow conditioners. This cuts piping length, reduces installation cost and works in tight skid and space-constrained installations.
• Multi-variable in one device: Mass flow, density and temperature are measured simultaneously from one sensor, reducing instrument count, I/O points and wiring. Density output supports concentration and quality control directly in the line.
• Heartbeat Technology built in: Continuous sensor health monitoring, drift detection and TÜV-verified self-diagnostics generate compliance-ready verification reports — supporting ISO 9001 and plant integrity programs without process shutdown.
• Flexible I/O and remote access: Up to 4 configurable I/O channels support 4–20 mA HART, PROFIBUS PA, FOUNDATION Fieldbus or Modbus. Local operation via touch display plus optional WLAN enables commissioning and reading from a phone or tablet.

Typical Applications

• Chemical & Petrochemical — mass flow and density of solvents, acids, alkalis and feedstock blending
• Oil & Gas — custody transfer, allocation metering, flare gas and refined product measurement
• Pharmaceutical — CIP/SIP batching, solvent recovery and clean-in-place verification
• Food & Beverage — dosing, sugar/fruit concentrate Brix via density, and CIP return monitoring
• Power & Energy — condensate, fuel oil and additive injection measurement
• Pulp & Paper — black liquor and chemical dosing where conductivity varies widely

Selection & Configuration Notes

Choosing the right Promass F 500 option depends on your medium, line size and certification needs:

• Line size: DN 8 to DN 250 (3/8" to 10") covers most process lines; select based on maximum flow velocity of 1–10 m/s for liquids.
• Wetted parts: Standard 316L stainless steel for general service; specify Hastelloy C22 for corrosive chlorides, acids and abrasive slurries.
• Temperature: Standard range −50 to +150 °C; extend to −196 °C for LNG/cryogenic service or +200 °C for high-temperature oils.
• Output: HART for analog retrofits; PROFIBUS PA or FOUNDATION Fieldbus for DCS integration; Modbus for PLC/SCADA connectivity.
• Approvals: ATEX, IECEx, FM, CSA and NEPSI versions available — confirm your required hazardous-area zone before ordering.

FAQ

Q1: Does Promass F 500 require straight pipe runs?
A: No. The Coriolis measuring principle is unaffected by flow profile, so no upstream or downstream straight sections or flow conditioners are needed.

Q2: Can it measure gas and liquid with the same device?
A: Yes. One sensor measures both phases; gas accuracy is ±0.25% of reading, while liquid accuracy reaches ±0.10% standard or ±0.05% with PremiumCal.

Q3: What is the difference between Promass F 500 and Promass A / E?
A: F 500 is the heavy-duty process line for DN 8–250 with remote transmitter and custody-transfer accuracy; A is for small-DN high-precision dosing, E is the economy compact version for utilities.

Q4: Is Heartbeat verification accepted for ISO 9001 and custody transfer?
A: Yes. Heartbeat Technology is TÜV-verified and produces traceable verification reports used in QS audits and, with the correct calibration, in fiscal/custody applications.
