Product Description

Product Description

Product Overview

The Emerson Rosemount 8711 Electromagnetic Flowmeter is a state-of-the-art flow measurement solution designed for precision, reliability, and versatility across a wide range of industrial applications. Utilizing Faraday's Law of Electromagnetic Induction, the device measures the flow rate of conductive liquids, including water, acids, slurries, and corrosive fluids, with exceptional accuracy. Engineered for demanding environments, it is widely employed in industries such as water and wastewater treatment, chemical processing, food and beverage, and power generation. The Rosemount 8711 features a robust construction with no moving parts, minimizing wear and maintenance while ensuring long-term operational integrity. Its advanced design integrates seamlessly into modern process control systems, offering real-time data acquisition and compatibility with digital communication protocols.

Advanced Measurement Performance and Reliability

The Rosemount 8711 excels in delivering high-precision flow measurements even under challenging conditions. Its optimized sensor design, coupled with Emerson's patented SignalCheck™ diagnostics, ensures stable performance in the presence of air bubbles, solids, or varying fluid conductivities. The flowmeter achieves accuracy levels up to ±0.15% of reading, surpassing industry standards for critical applications. The device's ceramic-coated electrodes and abrasion-resistant liner enhance durability in abrasive or corrosive media, while its immunity to viscosity, density, and temperature fluctuations guarantees consistent results. Additionally, the Rosemount 8711 supports bidirectional flow measurement, making it ideal for processes requiring reverse flow monitoring. With a turndown ratio of 1,000:1, it maintains precision across a broad flow range, eliminating the need for multiple meters in dynamic systems.

User-Centric Design and Smart Functionality

Sustainability and Cost Efficiency

Emerson's focus on user convenience is evident in the Rosemount 8711's intuitive interface and advanced connectivity options. The flowmeter features a large, backlit LCD display with multilingual menus for easy configuration and real-time data visualization. Integrated Bluetooth® technology enables wireless setup and monitoring via the Emerson Smart Meter App, reducing downtime during installation and maintenance. The device supports multiple output options, including 4–20 mA, pulse, and digital protocols like HART®, Foundation Fieldbus, and PROFIBUS PA, ensuring compatibility with existing control systems. Built-in diagnostics proactively alert users to issues such as electrode coating, empty pipe conditions, or signal degradation, enabling predictive maintenance and minimizing unplanned outages. Furthermore, its modular design allows for field upgrades, ensuring adaptability to evolving process requirements without full system overhauls.

The Rosemount 8711 is engineered to enhance operational sustainability while reducing total cost of ownership. Its low-energy consumption design aligns with global energy efficiency initiatives, and its long service life reduces waste from frequent replacements. The flowmeter's maintenance-free operation, coupled with Emerson's global support network, ensures minimal lifecycle costs. Compliance with international standards such as SIL 2/3, ATEX, and IECEx certifies its suitability for hazardous areas, while its hygienic configurations meet EHEDG and 3-A standards for sanitary applications. By optimizing process efficiency, minimizing leaks through precise leak detection, and enabling resource conservation, the Rosemount 8711 contributes to sustainable industrial practices. Its ability to integrate with Emerson's Plantweb™ ecosystem further empowers users to achieve digital transformation goals, leveraging data-driven insights for smarter decision-making and improved operational outcomes.

Step		Procedure
1	Site Selection	Choose a location with minimal vibration, away from strong electromagnetic fields. Ensure straight pipe runs (5D upstream, 2D downstream) for accurate measurement.
2	Mounting Orientation	Install the flowmeter in a horizontal, vertical (upward flow), or inclined position. Avoid air bubbles in vertical downward flow.
3	Pipe Alignment	Ensure flanges are parallel and concentric. Use gaskets without internal protrusions. Tighten bolts evenly.
4	Grounding	Connect grounding rings or electrodes to a dedicated earth ground (≤1Ω resistance) to eliminate electrical noise.
5	Wiring	Connect power (100-240V AC or 20-28V DC) and output signals (4-20mA, pulse, HART) per terminal diagram. Use shielded cables for signal lines.
6	Configuration	Set parameters (units, K-factor, damping) via local keypad or HART communicator. Verify empty pipe zero calibration.
7	Commissioning	Gradually fill the pipe, check for leaks, and verify output signals match process conditions.
8	Maintenance	Periodically inspect electrodes, grounding, and calibration. Clean electrodes if buildup occurs.
