The Micro Motion R150S is a premier 316L Stainless Steel sensor engineered specifically for high-performance in general purpose applications. As a versatile 1.5-inch DN40 model, it delivers a repeatable and reliable measurement while maintaining a small footprint, making it the ideal choice for process skids where space is at a premium.
The R150S offers maximum process flexibility for industrial plants handling a wide variety of fluids. Its compact and drainable design ensures that the meter can be installed in tight configurations without compromising performance. With a sensor maximum working pressure of 1,450 psig (100 barg), this robust measurement tool easily handles high-pressure industrial requirements.
Designed to reduce the total cost of ownership, the R150S can be configured with an integral transmitter, creating a streamlined, flow-variable-only architecture. This setup simplifies wiring and integration, making it a highly cost-effective Coriolis meter for facilities looking to upgrade from legacy volumetric technologies.
One of the core benefits of the Emerson R-Series technology is its long-term reliability. As a low-maintenance flow meter with no moving parts to wear or replace, the R150S minimizes downtime and operational expenses. This makes it a perfect fit for continuous chemical dosing and basic volume flow measurement tasks.
Safety is paramount in process control. The R150S carries a broad range of meter approvals, including ATEX, IECEx, NEPSI, and CSA (Class 1 Div 1). Its rugged construction provides the highest immunity to vibration and process noise, ensuring stable readings in the most challenging plant conditions.

Accuracy Needs: While the standard mass flow accuracy is ±0.50%, choose the optional high-performance ±0.40% calibration for more critical blending processes.
Transmitter Choice: Select the Class I, Div 1 housing with a local-operator interface if on-site adjustments are frequently required.
Orientation: To maximize the drainable feature, vertical-up installation is preferred. This prevents air trapping and ensures a consistent zero point.
Location: Thanks to the compact design, the R150S can be installed virtually anywhere. However, ensure it is not subjected to extreme pipe stress to maintain measurement integrity.
Zero-Point Stability: Periodically check the zero point during scheduled shutdowns to ensure long-term precision.
Diagnostic Tools: Utilize the advanced diagnostics available through the integral transmitter to monitor sensor health without interrupting the process.
Q1: What is the mass flow accuracy of the Micro Motion R150S?
A: The R150S features a standard mass flow accuracy of ±0.50% for liquid applications. However, an optional high-performance calibration is available to achieve an accuracy of ±0.40%.
Q2: Does the R150S support self-drainage?
A: Yes. The R150S is designed with a compact and drainable sensor geometry. When installed in the correct orientation (such as vertical-up), it ensures complete fluid removal, which is ideal for process cleaning.
Q3: Is the R150S certified for use in hazardous areas?
A: Absolutely. The R150S carries a broad range of global approvals, including ATEX, IECEx, NEPSI, and CSA (Class 1 Div 1), making it safe for use in explosive and hazardous industrial environments.
