In the demanding intersection of sterile integrity and high-throughput production, the Micro Motion H400F (DN100) stands as the unrivaled industry leader. Engineered specifically for 4-inch hygienic pipelines, this Coriolis meter combines global 3-A and EHEDG certifications with a premium 15 Ra (0.4 μm) electropolished finish. It is the definitive solution for high-capacity applications that require absolute cleanliness, such as vaccine production, sterile dairy processing, and high-purity beverage batching.
For biopharmaceutical and sterile food processes, the internal surface finish is the first line of defense against contamination. The H400F’s optional 15 Ra (0.4 μm) finish provides an ultra-smooth surface that minimizes protein binding and bacterial adhesion. Coupled with its self-draining sensor geometry, it ensures that during CIP (Clean-in-Place) and SIP (Steam-in-Place), all fluids are fully evacuated, eliminating the risk of batch-to-batch cross-contamination.
In large 4-inch lines, even a minor measurement drift can result in significant financial loss. The H400F delivers a staggering liquid mass flow accuracy of up to ±0.05% and a density accuracy of up to ±0.0005 g/cm³. This "fiscal-grade" performance makes it the ideal meter for high-value ingredient dosing and sterile bulk loading where every drop counts.

Whether you are handling viscous biological slurries or foaming dairy products, the H400F excels under pressure. Equipped with advanced MVD (Multivariable Digital) technology, it maintains stable measurement even in two-phase flow conditions (entrained air). Furthermore, the Smart Meter Verification (SMV) feature allows you to verify the meter’s health and calibration on-site in under 90 seconds without breaking the sterile seal—a critical advantage for maintaining FDA and GMP compliance.
Q: Does the H400F require straight pipe runs for installation?
A: No. Unlike magnetic or ultrasonic meters, the H400F Coriolis meter is immune to flow profile disturbances. It can be installed in compact skids or near elbows without losing its ±0.05% accuracy.
Q: Is the 15 Ra finish achieved through electropolishing?
A: Yes. The 15 Ra (0.4 μm) finish is a high-grade electropolished surface designed specifically for the stringent requirements of the pharmaceutical and biotech industries.
Q: Can this meter measure both gas and liquid?
A: Absolutely. While optimized for liquids, the H400F provides high-accuracy gas mass flow measurement (up to ±0.35%), making it versatile for carbonation or sterile gas dosing.
