The Micro Motion ELITE CMFS025H is the industry standard for low-flow measurement in the most aggressive environments. Engineered with Nickel Alloy C22 wetted parts, this 1/4-inch (DN6) sensor offers superior corrosion resistance and an extraordinary pressure rating of 3,626 psig (250 barg). It is specifically designed to deliver ±0.10% liquid mass flow accuracy for critical dosing, chemical injection, and laboratory applications where failure is not an option.
Ultimate Corrosion Resistance: Nickel Alloy C22 provides immunity to a wide range of aggressive chemicals, including oxidizing acids and chlorides.
High-Pressure Reliability: Rated for up to 3,626 psig (250 barg), making it the premier choice for offshore chemical injection and high-pressure sampling.
Peak Measurement Accuracy: Achieve ±0.10% liquid accuracy and ±0.25% gas accuracy, ensuring absolute process control.
Self-Draining Compact Design: The CMFS geometry ensures the sensor is fully drainable, minimizing fluid entrapment and facilitating easy cleaning.
Smart Meter Verification (SMV): Gain real-time assurance of meter health and calibration integrity without interrupting your process.
Extreme Thermal Range: Operates flawlessly from -400°F to 662°F (-240°C to 350°C), covering everything from cryogenic to high-heat applications.
Global Hazardous Certification: Fully certified by ATEX, IECEx, CSA, and NEPSI for use in Zone 1/Div 1 environments with SIL2/SIL3 safety ratings.

Q: Why choose Nickel Alloy C22 over 316L Stainless Steel for the CMFS025?
A: While 316L is suitable for many fluids, C22 is essential for aggressive media like sour gas, hot chlorides, or strong acids that cause pitting and stress corrosion cracking in stainless steel.
Q: Is this meter suitable for gas dosing?
A: Yes. The CMFS025H provides high-precision gas measurement (±0.25% accuracy), which is ideal for high-pressure gas sampling and catalyst dosing.
Q: Can I verify the meter's performance without removing it from the line?
A: Absolutely. With Smart Meter Verification (SMV), you can perform a full diagnostic of the meter's health and tube integrity while the process is running.
