Rosemount 8705 Flanged Magnetic Flow Meter Sensors

Precision Engineering Defines Rosemount 8705 Flow Meter

The Rosemount 8705 Flanged Magnetic Flow Meter embodies precision engineering excellence for fluid measurement applications across industrial and municipal sectors. Crafted with fully welded stainless construction, this sensor achieves a hermetic seal that protects against moisture and contaminants, ensuring sustained reliability even within aggressive environments. As part of Emerson’s trusted Rosemount series, the 8705 model guarantees high-performance measurement accuracy and long-term operational stability. Its obstructionless design delivers maintenance-free operation, eliminating mechanical wear commonly seen in turbine or paddle meters. This meter stands as a benchmark in durability, trusted globally in utility water systems, pulp and paper plants, chemical handling, and mineral processing. Each sensor unit represents Emerson’s dedication to precision, durability, and ease of integration—a true embodiment of engineering perfection for continuous process reliability.

Superior Construction Promoting Durability and Long-Term Reliability

At the foundation of the Rosemount 8705 lies its robust design philosophy aimed at enduring harsh process conditions while maintaining consistent performance over decades of use. Its fully welded stainless-steel housing offers an unmatched hermetic seal, safeguarding internal components from corrosion and contamination. The sealed enclosure resists liquid ingress, while IP68 submergence protection (with sealed cable glands) allows confident installation in partially submerged environments. This heavy-duty protection eliminates the need for frequent maintenance, enabling installations in environments such as mining slurry systems, desalination lines, or offshore water networks. Emerson’s attention to design not only ensures longevity but prevents installation-related damage and leading-edge wear by including optional lining protectors. Collectively, these features grant the 8705 sensor outstanding service continuity even under extreme vibration, pressure, or chemical exposure—making it a trusted instrument among flow control professionals worldwide.

Advanced Accuracy and Performance Under Flow Turndown Conditions

The Rosemount 8705 achieves exceptional measurement accuracy—up to ±0.15% of volumetric flow rate under 13:1 turndown and ±0.25% under 40:1 ranges. This precision enables reliable quantification of liquids from ultra-clean water to viscous chemical mixtures. The meter performs effortlessly through turbulent, laminar, and transitional flow regimes, making it universally applicable across industries demanding both stability and speed. As a magnetic flow meter, it offers no moving parts and minimal pressure drop, allowing unimpeded fluid passage while providing real-time digital measurements compatible with all Rosemount Model 8700 Series transmitters and legacy versions such as 8712C, 8732C, and 8742C. Operators appreciate that calibration remains stable across wide flow variations—ideal for batching, custody transfer, and continuous process control. With its internal electronics securely sealed, even temperature or humidity fluctuations cannot affect sensor fidelity or zero-point drift, ensuring lasting accuracy from commissioning to decades of operation.

Simplified Maintenance and Field Repair Capabilities

Designed with maintenance efficiency at its core, the Rosemount 8705 includes a removable, replaceable terminal block that simplifies repairs directly at installation sites. This modular approach cancels the costly need for full meter replacements during servicing. Emerson engineers designed the 8705 to minimize lifecycle costs while maximizing uptime—especially valuable for global industries where shutdowns translate to substantial financial losses. Optional secondary containment compartments surrounding electrodes provide additional safety by preventing process fluid leakage. The meter’s obstructionless structure further ensures uninterrupted performance; without moving parts, clogging or mechanical degradation simply does not occur. Field technicians can access wiring sections safely and rapidly without disturbing calibration setups. The design philosophy, blending service practicality with operational resilience, has made the Rosemount 8705 one of the most field-friendly electromagnetic sensors for large-scale facilities requiring immediate restoration and continuous reliability.

Dedicated Application Scope Across Multiple Industries

The versatility of Rosemount 8705 Flanged Magnetic Flow Meter Sensors lies at the heart of its popularity. In water and wastewater management, it supervises flow rates for distribution accuracy, billing verification, and treatment optimization. Chemical manufacturers use it within dosing and blending lines to track reactive volumes with precision while safeguarding against contamination through corrosion-resistant liners such as PTFE, ETFE, and PFA. Food and beverage plants integrate the sensor into bulk liquid transfer and CIP (Clean-In-Place) systems for hygienic compliance. Mining operations employ its rugged construction for slurry flow analysis and mineral extraction circuits under high abrasion conditions, while municipal utilities install it for stormwater monitoring and leak detection networks. Its universal flange compatibility—covering ASME, DIN, AWWA, and Australian standards—empowers deployment in both legacy and newly engineered infrastructures worldwide, establishing Rosemount 8705 as the industry’s benchmark in fluid measurement adaptability.

Certified Reliability and Material Flexibility for Custom Solutions

The Rosemount 8705 offers material customization that enhances compatibility across process chemistries and environmental challenges. Liner selections include PEX, PTFE, ETFE, PFA, Polyurethane, Neoprene, and even Linatex natural rubber ideal for abrasive or chemical-resistant applications. Electrode materials extend from 316L stainless steel and nickel alloy to platinum, tantalum, and titanium—ensuring optimal corrosion and chemical resilience across varied industries. Each assembly complies with global flange standards: ASME B16.5 Class 150–2500, DIN PN10–40, AS2129 Table D & E, and AWWA C207 Table 3 Class D (for 30–36 inch). Such adaptability ensures mechanical integrity while meeting engineering codes globally. Tested for leakage, stability, and temperature tolerance, the meter’s IP68 submergence certification confirms environmental readiness unmatched by most competitors. When combined with Smart Meter Verification functionality from compatible transmitters, its durability transforms into globally certified reliability—guaranteed through decades of uninterrupted measurement performance even under severe conditions.
