When processing bulk hygienic fluids, the Micro Motion H400S (DN100) is the industry’s most trusted high-precision solution. As a specialized 4-inch Coriolis meter, it not only meets stringent 3-A and EHEDG compliance but also ensures product consistency and minimizes waste through its unique self-draining design and industry-leading density measurement accuracy.
The sensor geometry of the H400S is specifically engineered for total self-drainage when installed in a vertical orientation. This ensures zero product holdup between batches, significantly enhancing the effectiveness of Clean-in-Place (CIP) and Steam-in-Place (SIP) cycles. For 4-inch high-flow lines, this design translates to thousands of dollars saved annually in reduced flush water and chemical cleaning agents.
Whether in dairy reception or large-scale beverage blending, the H400S delivers a staggering liquid mass flow accuracy of up to ±0.05%. This level of precision makes it the ideal "cash register" for custody transfer applications, effectively eliminating inventory shrinkage and billing disputes caused by measurement drift.

In modern production environments, operators frequently struggle with entrained air or two-phase flow causing measurement instability. The Micro Motion H400S utilizes advanced MVD (Multivariable Digital) technology to actively compensate for multiphase conditions. Whether you are handling high-viscosity food slurries, foaming dairy products, or performing cryogenic sanitary filling, the H400S provides a stable and continuous reading.
Furthermore, the integrated Smart Meter Verification (SMV) allows you to verify the sensor’s health and calibration without breaking the process seal. In pharmaceutical manufacturing, this provides a reliable digital audit trail, simplifying compliance with FDA and GMP validation requirements.
Q: Can the H400S handle slurries with solid particles? A: Absolutely. Because the H400S features smooth 316L Stainless Steel tubes with no moving parts, it is ideal for hygienic slurries containing soft solids or high viscosities without the risk of mechanical wear or clogging.
Q: What is the benefit of the 15 Ra finish over the 30 Ra finish? A: While 30 Ra (0.8 μm) is the standard for many food applications, the 15 Ra (0.4 μm) electropolished finish offers an ultra-smooth surface that prevents protein binding and bacterial adhesion—essential for biotech and sterile pharmaceutical processes.
Q: How do I verify the H400S calibration without pulling it from the line? A: Using the Smart Meter Verification (SMV) tool, the meter performs an internal structural integrity check in under 90 seconds. This generates a report that satisfies regulatory requirements for meter validation without interrupting your process.
