Micro Motion 4200 2-Wire Transmitter

The 4200 2-wire Coriolis meter lowers capital expenditures and provides a faster commissioning time with the ability to share power and signal over the same pair of wires reducing installation, engineering, and planning costs. The 2-wire Coriolis meter does not require any straight runs or flow conditioning providing a robust, repeatable, and reliable solution with no moving parts, and wide turndown, improving product quality leading to less rework and waste.

• Available with a wide range of Coriolis mass flow sensors with up to +/-0.10% mass flow accuracy and +/0.0005 g/cc density accuracy for liquids and slurries or +/-0.25% mass flow accuracy for gases.
• The integrated real-time clock time stamps process data, alerts, Smart Meter Verification reports and audit logs. Data Historian on board offers a complete audit trail to determine process issues.
• Graphic display that supports 8 languages and can be rotated using the integrated software rotation without removing the front cover, thereby minimizing downtime due to hot work permit restrictions.
• Replace existing 2-wire flow devices with minimal effort and without incurring additional power or cabling costs.
• Easily expand your plant where power is not centrally located
• Smart Meter Verification provides a quick, complete assessment of a Coriolis meter, determining whether the meter has been affected by erosion, corrosion, or other influences affecting meter calibration. A basic version of Smart Meter Verification is included as standard.
• Certified for SIL2 single use and SIL3 multiple use safety applications per IEC 61508
• Accurate, repeatable, direct mass measurement improves process control while reducing number of measurement devices required.
• Wireless THUM™ option maximizes installation and operation flexibility.

1. Game-Changing 2-Wire Architecture

· Significant Cost Savings: Utilizes a standard 4-20 mA 2-wire loop, eliminating separate power cables. Can save up to 50% on installation costs (including cables, wiring, conduit, and labor).

· Seamless Replacement & Integration: Directly replaces existing 2-wire transmitters (e.g., vortex, magnetic) and integrates easily into any standard DCS or PLC system without modifying existing wiring infrastructure.

2. True Coriolis Performance

· Direct Mass Flow Measurement: Provides direct, high-accuracy mass flow measurement, ensuring fundamental accuracy without the conversions or compensations required by traditional flow technologies.

· Multi-Variable Output: Delivers mass flow, density, temperature, and other key process variables simultaneously from a single device.

3. Ultimate Installation Simplicity

· Simple Wiring: Cuts wiring effort in half compared to 4-wire devices, drastically simplifying installation and reducing the potential for errors.

· Space Saving: Simpler wiring requires less space in control cabinets and field junction boxes.

4. Intrinsic Safety and Low Power

· Low Power Design: Engineered specifically for 2-wire loops with very low power consumption, facilitating intrinsic safety approvals.
