E+H Proline Promass S 500 Coriolis Flowmeter

Hygienic Coriolis Mass Measurement with Remote Processing

Maintaining uncompromised product purity, biological safety, and accurate mass flow monitoring in food, beverage, and biotechnology processing is essential for meeting international sanitary standards. The Endress+Hauser Promass S 500 Coriolis Mass Flowmeter represents a premium metering solution designed specifically for sterile, hygienic, and corrosion-sensitive liquid applications where remote transmitter installation is required. As a professional global distributor of industrial automation instrumentation and process control devices, we supply authentic, original Endress+Hauser field instruments to support international plant installations and system retrofits.

The Promass S 500 sensor features a fully self-drainable single-tube geometry that eliminates internal pockets, dead legs, and crevices where bacteria or fluid residue could accumulate. Constructed from high-grade stainless steel 1.4435 (316L) with electropolished surface finishes, the sensor is fully compatible with aggressive chemical Clean-in-Place (CIP) and Sterilization-in-Place (SIP) procedures. Certified under 3-A, EHEDG, and FDA sanitary standards, it guarantees total process security when handling sensitive media such as active pharmaceutical ingredients (APIs), purified water, dairy products, beverages, and liquid food additives.

Remote Transmitter Architecture & Flexible Multi-Signal I/O

The key feature of the Promass S 500 is its advanced remote transmitter platform, which enables long-distance separation between the inline measuring sensor and the control interface. This remote setup is particularly useful in washdown environments, cleanrooms, high-vibration skids, or elevated piping locations where local transmitter access is impractical.

Key signal and control capabilities include:

• Up to 4 Configurable I/Os: Fully flexible input/output configuration options (including active/passive 4-20 mA HART, pulse/frequency/switch output, relay outputs, and status inputs) without changing instrument hardware.

• Comprehensive Digital Fieldbuses: Built-in compatibility with HART, PROFIBUS DP/PA, FOUNDATION Fieldbus, Modbus RS485, PROFINET, EtherNet/IP, Ethernet-APL, and OPC-UA for fast integration into DCS and SCADA networks.

• User-Friendly Operating Modes: Access parameters locally via an optical touch display, remotely through an integrated web server, or wirelessly via Bluetooth using the SmartBlue application.

Simultaneous Multivariable Process Monitoring

Operating on the proven Coriolis principle of measurement, the Promass S 500 functions as a complete process analytical device rather than a single-function flow meter. A single inline installation continuously provides real-time tracking of four core process metrics:

• Mass Flow Rate

• Volume Flow Rate

• Fluid Density & Reference Density

• Process Medium Temperature

By capturing these multivariable metrics simultaneously, plant engineers can reduce inline pipe penetrations, eliminate redundant secondary sensors, and simplify process control loops in modular dosing skids and filling lines.

Embedded Quality Verification with Heartbeat Technology

To comply with strict ISO 9001 quality frameworks, cGMP guidelines, and SIL safety standards, the Promass S 500 includes Endress+Hauser’s Heartbeat Technology. This onboard diagnostic and verification suite continuously monitors sensor health, drive circuitry, and measurement accuracy in real time without interrupting active production runs. Maintenance personnel can trigger automated, tamper-proof device verifications directly from the control room or local display, generating traceable verification reports required for regulatory audits and predictive maintenance schedules.

Applications

• Food & Beverage Industry: Milk, dairy products, soft drinks, juices, liquid sugar, chocolate, syrups, edible oils, and CIP chemical dosing lines.

• Pharmaceutical & Biotechnology: Active pharmaceutical ingredient (API) metering, sterile liquid dosing, buffer solutions, cell culture fluids, and purified water distribution loops.

• Hygienic Process Skids: Clean-in-Place (CIP) / Sterilization-in-Place (SIP) stations, automated filling machines, pasteurization loops, and filtration skids.

• Personal Care & Cosmetics: Mass flow metering of creams, lotions, toothpastes, shampoos, and liquid soaps requiring sanitary process connections.

FAQ

Q1: What makes the Promass S 500 particularly suitable for hygienic applications? A1: The Promass S 500 features a fully self-drainable single-tube sensor built from 316L stainless steel with high-grade surface finishes. It contains no internal crevices, meets 3-A and EHEDG sanitary standards, and withstands continuous CIP/SIP cleaning.

Q2: Is your company the original manufacturer of the Promass S 500? A2: No, we are an independent global supplier and distributor of process automation instrumentation. We source original, brand-new Endress+Hauser devices with full factory documentation, selection assistance, and international export support.

Q3: What is the primary advantage of the Promass S 500 remote transmitter design? A3: The remote design allows the transmitter display to be installed up to several hundred meters away from the measuring point. This protects electronics from hot, vibrating, or high-pressure washdown environments while giving operators convenient access to controls.

Q4: How does Heartbeat Technology help during quality audits? A4: Heartbeat Technology performs non-disruptive, real-time device health checks while processes are running. It creates tamper-proof electronic verification reports compliant with ISO 9001 and FDA quality management requirements without interrupting production.
