The Micro Motion G050M is a high-performance 316L Stainless Steel sensor engineered for precision in an ultracompact footprint. As the premier 1/2-inch (DN15) model in its class, it is ideally suited for both standard and sanitary environments, providing world-class mass flow and density measurement where installation space is severely limited.
The G050M solves the challenge of tight piping configurations in modern modular plants. Its lightweight design (only 10 lbs for the CL150 version) and short face-to-face dimensions (9.82") make it the top choice for mobile installations and small-scale skids. Despite its small size, it remains a robust measurement solution with a sensor maximum working pressure of 1,450 psig (100 barg).
Precision is the hallmark of the G050M. While it offers reliable standard mass flow accuracy, users can choose an optional high-performance package to achieve an industry-leading liquid mass flow accuracy of ±0.10%. This level of precision, combined with laser-etched tagging for long-term durability, ensures your product consistency is maintained even in the most challenging industrial dosing environments.
For life science and food industries, hygiene is non-negotiable. The G050M features ultimate installation flexibility with a self-draining capability that ensures no fluid entrapment. It is fully compliant with 3-A, EHEDG, and ASME BPE standards. To further prevent bacterial growth, it is available with an improved surface finish stainless steel option of up to 15 Ra (0.4 μm), making it perfect for rigorous SIP and CIP cycles.
Gain measurement integrity assurance without interrupting your production. Integrated Smart Meter Verification (SMV) allows you to audit the health of the sensor and electronics in real-time while the meter remains in-process. Coupled with SIL 2 and SIL 3 safety ratings and a broad range of meter approvals (ATEX, IECEx, CSA, NAMUR), the G050M provides the long-term reliability required for mission-critical chemical dosing and sanitary batching.

Choosing the right configuration for the G050M is effortless using MyEmerson tools. Whether you require broad connectivity for a distributed control system or a stand-alone transmitter, the G050M integrates seamlessly with modern Micro Motion electronics.
Thanks to its lightweight design, the G050M is easy to handle during installation and maintenance. To ensure the highest accuracy, follow the self-draining orientation guidelines, especially in sanitary applications where total fluid removal is required after a batch.
Q1: How small is the Micro Motion G050M sensor? A: The G050M is designed for maximum space savings. For the CL150 flange version, the face-to-face length is only 9.82 inches (24.9 cm) and it weighs just 10 lbs (4.5 kg), making it one of the most compact 1/2-inch Coriolis meters in the world.
Q2: Can the G050M be used for high-precision chemical dosing? A: Yes. While the standard accuracy is excellent, we offer an optional high-performance calibration that achieves ±0.10% liquid mass flow accuracy, which is ideal for critical dosing and additive injection.
Q3: Is the G050M compatible with both horizontal and vertical piping? A: Absolutely. The G050M features a self-draining sensor geometry that provides ultimate installation flexibility. Whether installed horizontally or vertically, it ensures no fluid entrapment, supporting hygienic CIP/SIP processes.
