Natural gas valve skid equipped with a Micro Motion F100A Coriolis flowmeter and a 5700 field-installed transmitter.

The Emerson Micro Motion 5700 Transmitter is a central component within the industry-leading Micro Motion Coriolis flow and density measurement portfolio. Representing a significant evolution in signal processing technology, this transmitter is engineered to unlock the full potential of its paired sensor, delivering unparalleled accuracy, reliability, and rich diagnostic data for the most demanding process applications. It serves as the intelligent brain, converting the raw sensor signals into precise, actionable information for critical processes in industries such as oil and gas, chemical and petrochemical, pharmaceutical, food and beverage, and power generation. The 5700 platform is designed not merely as a measurement device but as a foundational tool for process optimization, asset health monitoring, and ensuring the highest levels of quality control.

At its heart, the Micro Motion 5700 Transmitter utilizes advanced digital signal processing (DSP) algorithms. These sophisticated algorithms are designed to meticulously analyze the complex waveform data received from the Coriolis sensor tubes. This enhanced processing power provides several critical advantages over previous generations and competing technologies. Firstly, it achieves exceptional measurement accuracy and stability for mass flow, density, temperature, and derived volumetric flow, even in the presence of process noise or external vibrations. This stability is crucial for applications like batching, custody transfer, and recipe formulation where minute measurement errors can lead to significant financial loss or product quality issues.

Secondly, the transmitter's robust processing capabilities enable superior performance in challenging fluid conditions. It excels at handling multi-phase flows (e.g., entrained gas in a liquid), low flow rates, and highly viscous products, situations where other flow technologies often struggle or fail. The 5700's ability to maintain a stable measurement under these conditions provides users with confidence in their data and reduces the need for manual intervention or verification.

The 5700 Transmitter is packed with features that emphasize ease of use, integration, and predictive capabilities:

• Intuitive User Interface: The transmitter features a large, backlit, graphical LCD display and a simple, menu-driven navigation system. This allows technicians to view all process variables simultaneously, perform configuration tasks, and access diagnostics quickly and easily on-site, without the need for external tools.

• Flexible Communication and Integration: It supports a wide array of industry-standard digital communication protocols, including the foundational HART® protocol, FOUNDATION™ Fieldbus, PROFIBUS PA, and Ethernet/IP. This flexibility ensures seamless integration into virtually any existing or new control or asset management system, enabling both remote configuration and the extraction of valuable process and device data.

• Built-in Advanced Diagnostics: A standout feature of the 5700 is its suite of embedded diagnostics. Tools like the Purity Predictor can indicate the presence of a second phase in the fluid (e.g., air in liquid), while the Health Predictor continuously monitors the mechanical condition of the sensor, assessing factors like coating, corrosion, and structural integrity. This moves maintenance from a reactive or scheduled basis to a predictive model, preventing unplanned downtime.

• Dual-Channel Capability: Certain models of the 5700 transmitter can be configured to accept input from a second, external pressure or temperature transducer. This allows for powerful compensated flow calculations (e.g., mass flow compensation for natural gas) within a single device, simplifying system design and improving overall measurement accuracy.

• Rugged Design and Safety: Housed in a robust, cast aluminum enclosure with a high ingress protection rating (IP66/NEMA 4X), the transmitter is built for harsh industrial environments. It also carries critical safety certifications, including SIL 2 and SIL 3 (Safety Integrity Level) according to IEC 61508, making it suitable for use in safety instrumented systems.

The Micro Motion 5700 Transmitter is the ideal choice for a vast range of applications where precise mass-based measurement is critical. This includes:

• Custody Transfer of Liquefied Natural Gas (LNG) and other hydrocarbons.

• Chemical Reactor Feed and Product Blending.

• Batch and Recipe Formulation in Pharmaceuticals and Food Production.

• Catalyst Injection and Additive Dosing.

• Boiler Feedwater and Fuel Flow Measurement in Power Plants.

In summary, the Emerson Micro Motion 5700 Transmitter is more than a signal converter; it is a sophisticated process insight engine. By combining powerful digital processing with user-centric design and predictive diagnostics, it provides unprecedented levels of measurement confidence, operational efficiency, and asset protection, solidifying the position of Coriolis technology as the ultimate flow and density measurement solution.
