Description

Designed for highly reliable steam, liquid, and gas flow measurement, the Rosemount 8800DF120SA1N7D1E1I1M5C4CN7Q4Q8 is an industrial inline vortex flowmeter utilizing a non-clogging sensor design to eliminate impulse lines and potential leak points. This specific configuration features a massive 12-inch (300 mm) flanged body constructed of robust CF-3M cast stainless steel and 316 wrought stainless steel wetted materials, capable of handling demanding industrial process environments.

The system is equipped with 4-20 mA digital electronics running the HART communication protocol, enabling seamless diagnostic monitoring and configuration. To ensure operator clarity on-site, a high-visibility M5 LCD display is built directly into the rugged stainless steel transmitter housing, which is configured with two M20 x 1.5 conduit entries. For safety compliance, this model comes certified with ATEX dual protection—both Flameproof (E1) and Intrinsic Safety (I1)—and includes comprehensive Q4 calibration and Q8 material traceability documentation.

Features

• All-Welded Design: Eliminates internal gaskets, ports, and bypass lines, preventing process bypass and potential leak paths.
• Adaptive Digital Signal Processing: Provides reliable flow signal tracking while filtering out ambient process vibration.
• ATEX Dual Certification: Flameproof and Intrinsic Safety approvals for deployment in classified hazardous industrial zones.
• Local Operator Interface: Includes an integrated M5 LCD indicator showing process variables and diagnostics.
• Configurable Alarms: Dual NAMUR C4 (high alarm) and CN (low alarm) saturation and alarm values protect process equipment.
• Quality Documentation: Ships with ISO 10474 3.1/EN 10204 3.1 calibration and material traceability certificates.

Applications

• High-capacity steam utility lines and boiler feedwater monitoring.
• Industrial gas distribution and compressed air management.
• Chemical and petrochemical process fluid allocation.
• Power plant cooling water and condensate loop measurement.

Installation Guidelines

• Straight Pipe Runs: To ensure accurate flow measurement, install the meter with a minimum of 10 nominal pipe diameters upstream and 5 nominal pipe diameters downstream of straight pipe, free from valves or fittings.
• Orientation: Can be installed in horizontal, vertical, or inclined piping. Vertical mounting with upward process flow is recommended to keep the sensor completely flooded.
• Conduit Sealing: Install appropriate certified cable glands or conduit seals in the M20 x 1.5 entries to maintain the NEMA 4X / IP66/67 environmental rating.
• Grounding: Always ground the transmitter housing to earth using the internal or external grounding screw terminals in accordance with local hazardous area codes.

Compliance and Certifications

• ATEX Directive compliance for hazardous area installations.
• Flameproof certification: ATEX II 2 G Ex d IIB+H2 T6 Gb (E1 option).
• Intrinsic Safety certification: ATEX II 1 G Ex ia IIC T4 Ga (I1 option).
• ISO 10474 / EN 10204 Type 3.1 material and calibration verification.
