E+H Proline Promag H 500 Electromagnetic Flowmeter

Advanced Hygienic Flow Measurement with Remote Processing

Ensuring absolute sterility, operational compliance, and precise fluid metering in large-scale hygienic manufacturing is essential for modern plant managers. The Endress+Hauser Promag H 500 Electromagnetic Flowmeter represents a top-tier flow measurement solution designed specifically for complex sanitary installations where the flow sensor must be separated from the control transmitter. As an established global distributor of industrial automation and process control instruments, we provide authentic, original Endress+Hauser field devices to support international engineering projects and plant modernizations.

The Promag H 500 sensor features a high-grade PFA liner and corrosion-resistant wetted parts, making it fully resistant to aggressive chemical CIP (Clean-in-Place) and SIP (Sterilization-in-Place) procedures. With sensor housings built from 304/316L stainless steel and wetted components certified under 3-A, EHEDG, and FDA guidelines, the device guarantees biological safety when handling sensitive process media such as purified water (PW), Water for Injection (WFI), dairy, liquid food, beverages, and active pharmaceutical ingredients (APIs).

Remote Transmitter Architecture & Configurable Signal I/Os

The core distinction of the Promag H 500 lies in its powerful remote transmitter platform, which allows flexible separation between the measuring point and the user control interface. This setup is particularly advantageous in hard-to-reach piping locations, high-vibration skids, or harsh washdown environments where local transmitter operation is impractical.

Key signal and control advantages include:

• Up to 4 Configurable I/Os: Fully customizable input/output channels (including active/passive 4-20 mA HART, pulse/frequency/switch output, relay outputs, and status inputs) without altering hardware configurations.

• Comprehensive Digital Protocols: Built-in support for HART, PROFIBUS DP/PA, FOUNDATION Fieldbus, Modbus RS485, PROFINET, EtherNet/IP, Ethernet-APL, and OPC-UA for direct integration into plant-wide DCS and SCADA enterprise networks.

• IP69 Sensor Connection Housing Option: Designed to withstand continuous high-pressure, high-temperature washdown procedures typical in sanitary production facilities.

Multivariable Process Monitoring and Zero Head Loss

Operating on Faraday’s law of electromagnetic induction, the Promag H 500 functions as a multi-parameter diagnostic sensor. Rather than measuring flow alone, a single inline unit simultaneously provides:

• Volume Flow Rate

• Process Temperature

• Fluid Conductivity & Corrected Conductivity

• Calculated Mass Flow & Corrected Volume Flow

Because the full-bore sensor contains no moving parts or internal flow restrictions, it causes zero head loss or pressure drop. This design minimizes pumping energy expenses, eliminates dead legs where bacterial cultures could grow, and maintains consistent accuracy even with 0 x DN inlet run requirements under fluctuating flow profiles.

Embedded Diagnostics and Compliance with Heartbeat Technology

To maintain strict quality control standards (such as ISO 9001, FDA 21 CFR Part 11, and SIL safety loops), the Promag H 500 incorporates Endress+Hauser’s Heartbeat Technology. This built-in diagnostic and verification suite operates continuously in the background without interrupting active process lines. Operators can run automated verification routines via local optical touch display, integrated web server, or remote network tools, instantly generating traceable verification reports for regulatory audits and predictive maintenance schedules.

Applications

• Food & Beverage Industry: Milk, dairy products, fruit juices, beer, liquid sugar, sauces, soft drinks, and CIP chemical dosing lines.

• Pharmaceutical & Biotechnology: Purified Water (PW), Water for Injection (WFI), buffer solutions, liquid active pharmaceutical ingredients, and cell culture media.

• Hygienic Process Skids: Large-scale OEM filtration skids, pasteurization loops, automatic CIP/SIP washing stations, and filling lines.

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

FAQ

Q1: What is the main structural difference between Promag H 100 and Promag H 500? A1: The Promag H 100 features an ultra-compact transmitter integrated directly on the sensor, ideal for tight space skids. The Promag H 500 utilizes a remote transmitter design supporting up to 4 I/Os, advanced fieldbus communication, and long-distance wiring between the sensor and control display.

Q2: Is your company the original manufacturer of the Promag H 500? A2: No, we are an independent global supplier and distributor of industrial instrumentation. We supply original, brand-new Endress+Hauser instruments with full factory documentation, technical selection advice, and international shipping support.

Q3: Can the remote sensor withstand outdoor or high-pressure washdown environments? A3: Yes, the remote sensor connection housing can be ordered with an optional IP69 enclosure rating, protecting it against high-pressure, high-temperature washdowns commonly used in sanitary processing environments.

Q4: How does Heartbeat Technology benefit regulatory audits? A4: Heartbeat Technology conducts real-time, non-disruptive device verification while process operations are running.
