The Micro Motion R-Series is the industry standard for general-purpose Coriolis flow and density measurement. Designed for applications that prioritize reliability and low maintenance, the R-Series features a low-footprint, drainable architecture that fits easily into existing piping. Constructed from versatile 316L Stainless Steel, these meters provide a robust alternative to traditional volumetric technologies, delivering direct mass flow data for better process control.
Compact & Drainable Design: The dual-curved tube geometry ensures the sensor is fully drainable, reducing product waste and footprint in skid-mounted systems.
Cost-Effective Performance: Ideal for utility and basic process applications where ELITE-level precision isn't required but Coriolis reliability is a must.
Broad Connectivity: Supports expansive I/O options including HART, Modbus, Ethernet/IP, PROFINET, and FOUNDATION Fieldbus for seamless digital integration.
Low Maintenance: With no moving parts to wear, clog, or replace, the R-Series significantly reduces total cost of ownership compared to mechanical flow meters.
Flexible Installation: The robust sensor design is immune to flow profile disturbances, allowing installation virtually anywhere without straight pipe runs.
Rugged Electronics: Available with integral or remote transmitters, including Class I, Div 1 / Zone 1 housing options with local operator interfaces.

Q1: Is the R-Series suitable for measuring density?
A1: Yes. While optimized for mass flow, the R-Series provides a reliable density measurement (accuracy up to ±0.003 g/cm³), which is often used for basic concentration monitoring and fluid identification.
Q2: Can I use the R-Series for hazardous area applications?
A2: Absolutely. The R-Series holds a broad range of global approvals, including CSA, ATEX, and IECEx for Class 1 Division 1 and Division 2 environments.
Q3: How does the R-Series improve on older flow technologies?
A3: Unlike DP meters or turbine meters, the R-Series measures mass flow directly. It is not affected by changes in fluid temperature, pressure, or viscosity, providing much higher long-term stability.
Q4: What electronics options are available?
A4: The R-Series is compatible with a wide range of Micro Motion transmitters, from simple 4-20mA HART units to advanced digital platforms like PROFINET and Ethernet/IP.
