Yokogawa ROTAMASS RCEP50S Coriolis Mass Flow Meter Product Introduction
The Yokogawa ROTAMASS RCEP50S is a high-performance Coriolis mass flow meter designed for precise measurement of liquid and gas flows across diverse industrial applications. Combining advanced sensor technology with robust construction, this device ensures reliability, accuracy, and adaptability in demanding environments. Below is a comprehensive overview of its features, specifications, and applications.
1. Product Overview
The ROTAMASS RCEP50S belongs to Yokogawa's renowned Coriolis flow meter series, leveraging the Coriolis effect to measure mass flow directly without requiring additional sensors for temperature or pressure compensation. Its dual bent-tube design compensates for environmental fluctuations, ensuring consistent accuracy even under extreme conditions.
Key Highlights:
Direct Mass Flow Measurement: Eliminates the need for secondary calculations, reducing measurement uncertainties.
Multi-Variable Output: Measures mass flow, density, temperature, and concentration simultaneously
Wide Application Range: Suitable for aggressive chemicals, high-viscosity fluids, gases, and mixed-phase media.
2. Key Features
2.1 High Precision and Stability
Accuracy: ±0.1% of rate for liquids and ±0.35% for gases, making it ideal for custody transfer and critical process control.
Turndown Ratio: Superior turndown capabilities ensure accurate measurement across a broad flow range, even at minimal flow rates.
Dual-Tube Design: Compensates for temperature, pressure, and density variations, enhancing repeatability in dynamic conditions.
2.2 Robust Construction
Material: Constructed from stainless steel (316L/1.4404 or alloy C-22 for corrosive applications), ensuring durability in harsh environments.
Temperature Range: Operates from -70°C to +350°C, accommodating extreme thermal conditions.
Pressure Rating: Withstands up to 700 bar (10,000 psi), suitable for high-pressure systems such as oil and gas pipelines.
2.3 Advanced Output and Communication
Output Options:
Analog: 4-20 mA (HART-enabled).
Digital: Modbus, HART, and pulse/status outputs for integration with PLCs and SCADA systems.
HART Protocol: Enables remote configuration, diagnostics, and real-time data monitoring
2.4 Diagnostic and Maintenance Features
Self-Testing: Built-in diagnostics for LCD, keypad, and sensor health checks to preempt failures
Historical Data: Stores event logs, alarms, and warnings for trend analysis and troubleshooting
Auto-Zero Function: Simplifies calibration and ensures long-term accuracy by compensating for zero drift
