The Micro Motion H300F (DN80) is a 3-inch hygienic Coriolis flow meter designed for high-volume processes that demand uncompromising purity. Constructed from 316L Stainless Steel and polished to a 15 Ra (0.4 μm) finish, the H300F meets the stringent global standards of 3-A and EHEDG. It is the industry standard for bulk milk reception, beverage bottling headers, and pharmaceutical base-stock transfer.

Unrivaled Surface Integrity: The 15 Ra finish minimizes bacterial adhesion and biofilm formation, making the H300F safe for high-purity biologicals and sensitive food products.
Rapid Product Change-Over: The self-draining S-series geometry ensures no fluid remains in the tubes after a batch, allowing for fast transitions between different flavors or formulas without cross-contamination.
Advanced Two-Phase Flow Capability: Specifically engineered to accurately measure flow even with entrained air or gas "slugs," which is critical for bulk unloading and tank bottom stripping.
Smart Meter Verification (SMV): High-capacity hygienic lines are costly to dismantle. SMV allows for real-time verification of the meter's calibration and structural health without breaking process connections.
Thermal Shock Resilience: Designed to handle the rapid temperature transitions of CIP (Clean-in-Place) and SIP (Steam-in-Place) cycles up to 350°C, maintaining a stable zero point for immediate accuracy.
Hygienic Transmitter Housings: Available in all-stainless steel housings for maximum resistance to harsh cleaning chemicals.
Seamless Digital Communication: Full support for HART, Modbus, PROFINET, and EtherNet/IP for easy integration into high-level control systems.
Multivariable Outputs: One H300F replaces multiple sensors by providing mass flow, volume flow, density, and temperature in a single hygienic unit.
The Challenge: A large dairy processing plant needed to measure raw milk intake from 3-inch tanker lines. The meter had to handle entrained air (common during unloading) and meet strict 3-A sanitary standards.
The Hanyu Solution: The plant installed the Micro Motion H300F from
The Result: The H300F’s two-phase flow technology accurately managed air bubbles during the start and end of the unloading process, providing a stable ±0.15% accuracy.
The Impact: Discrepancies between tanker invoices and plant receipts were reduced by 25%, and the 15 Ra finish allowed for faster, more efficient CIP cycles.
Q: Why is 15 Ra finish important for 3-inch lines?
A: In large-bore lines, internal surface area is significant. A 15 Ra (0.4 μm) finish ensures that even at high flow rates, there are no microscopic "pockets" where contaminants can settle, ensuring a truly sterile process.
Q: Can the H300F handle viscous hygienic fluids like honey or syrups?
A: Yes. The H300F is excellent for high-viscosity fluids, providing direct mass measurement that is independent of viscosity or flow profile changes.
Q: Is it suitable for hazardous locations within a food plant (e.g., alcohol distillation)?
A: Absolutely. It carries ATEX, IECEx, and CSA approvals for hazardous areas, making it safe for measuring spirits, solvents, or flavor extracts.
Q4: How does Hanyu Zhilian ensure the quality of these large hygienic sensors?
A: We supply 100% original factory equipment with full documentation: 3-A/EHEDG certs, Material Traceability Reports (MTRs), and original calibration data. All project data is confidential per our Privacy Policy.
