The Micro Motion T025F (DN6) is a 1/4-inch Coriolis meter engineered for precision measurement in compact, high-purity environments. Featuring a unique single straight-tube architecture made from Titanium Grade 9, it provides a plug-resistant, low-shear flow path that is ideal for sensitive fluids. Polished to an elite 15 Ra (0.4 μm) surface finish, this sensor is designed to meet the most stringent 3-A and EHEDG hygienic standards.

Micro-Flow Plug Resistance: In 1/4" lines, traditional curved tubes are prone to clogging by particulates or high-viscosity media. The T025F’s straight-tube design provides a clear, in-line path that stays clean longer.
Unmatched Surface Purity (15 Ra): The high-polish finish minimizes protein binding and microbial growth, making it the benchmark for pharmaceutical and biotech dosing applications.
Shear-Sensitive Integrity: By avoiding bends and turns, the T025F preserves the molecular structure of delicate fluids, such as vaccines, enzymes, and shear-sensitive polymers.
Corrosion-Resistant Titanium: Titanium Grade 9 offers superior chemical compatibility with chlorides and organic acids compared to standard 316L stainless steel.
Self-Draining & Easy CIP/SIP: The T025F is specifically designed for rapid Clean-in-Place (CIP) and Steam-in-Place (SIP), allowing for frequent product change-overs without cross-contamination.
Multivariable Digital (MVD) Technology: Directly measure mass flow, density, concentration, and temperature in one compact 1/4" unit.
Robust Installation: Unlike other micro-flow technologies, the T025F is highly resistant to process noise and requires no straight pipe runs, allowing for extremely compact dosing skid designs.
Smart Meter Verification (SMV): In-process verification ensures your micro-dosing line is accurate without ever breaking the sterile seal.
The Challenge: A biotech lab needed to dose a highly viscous and shear-sensitive nutrient into a fermenter. Standard curved-tube meters were causing product degradation and were impossible to drain completely between batches.
The Hanyu Solution: The lab integrated the Micro Motion T025F from
The Result: The straight-tube titanium path handled the viscosity without shearing the molecules. The 15 Ra finish ensured that every gram of expensive nutrient was either used or drained.
The Impact: Product yield increased by 12%, and sterile cleaning times were halved, significantly increasing the lab's throughput.
Q: Why use the T025F (15 Ra) instead of a standard stainless steel meter?
A: The T025F is used when you need both the corrosion resistance of Titanium and the ultra-smooth 15 Ra finish required for sterile environments where stainless steel might corrode or harbor bacteria.
Q: Can it measure gas in 1/4" lines?
A: Yes. It provides high-repeatability gas mass flow measurement with a stable accuracy of ±0.50%.
Q: Does it require a special transmitter?
A: It is compatible with Micro Motion transmitters like the 5700 or 2400, which allow for high-speed batching and advanced digital communication.
Q4: How does Hanyu Zhilian ensure the quality of these micro-flow sensors?
A: We supply 100% original factory units with full documentation, including Material Traceability Reports (MTRs), 3-A/EHEDG certifications, and original calibration certificates. Your project data is kept confidential per our Privacy Policy.
