The Yokogawa ROTAMASS Hygienic series is the premier metrological solution for high-purity, aseptic, and sterile fluid processing. Specifically engineered to comply with rigid international bioprocess standards, this sanitary Coriolis mass flow meter features self-draining bent tubes with zero dead-spaces. It provides continuous, drift-free tracking of mass flow, reference density, and temperature for applications where preventing batch contamination and maintaining absolute biological isolation are non-negotiable.
Fully certified under 3-A, EHEDG, EC 1935/2004, and EC 2023/2006 regulations. Surfaces feature mirror-polished 316L Stainless Steel (1.4404) wetted boundaries to ensure cleanability at a microscopic level.
Processes real-time multi-variable telemetry to compute online Brix/sugar concentration, precise reference density for bottling stability, and temperature-compensated viscosity indexing.
Withstands structural thermal shocks from -70°C up to +140°C (-94°F to +284°F). Designed to handle aggressive caustic washdowns and high-temperature steam sterilization cycles.
| Industrial Sector | Validated Process Applications |
|---|---|
| Food & Beverage | High-speed filling machine carbonation, premium fruit juice concentrate blending, raw milk tanker reception, molasses/sugar dosing loops, and alcoholic beverage proofing. |
| Pharma & Biotechnology | Nutrient feed tracking in high-yield bioreactors, continuous live fermentation monitoring, purified water-for-injection (WFI) loop recycling, and finished product quality custody. |
| Clean Plant Utilities | Aseptic process water reclamation lines, online CIP acid/base concentration dosing, and clean steam mass balance tracking. |
High-temperature Steam-in-Place (SIP) cycles inject extreme thermal stress into Coriolis sensors, causing momentary mechanical expansion of the wetted 316L measuring tubes. To verify baseline metrological stability prior to initiating the next product run, follow this field procedure:
Step 1: Cool-Down Tracking: Allow the automated sanitary flushing sequence to complete. Ensure the internal sensor tube temperatures drop back below +40°C (+104°F) and completely stabilize with process water or product buffer solution.
Step 2: Micro-Bubble Purge: Flood the line at maximum pump velocity for 30 seconds to push out any trapped steam pockets or ambient micro-bubbles out of the sensor tubes.
Step 3: Direct Zero-Verification: Close the hygienic isolation valves to achieve a absolute zero-velocity fluid state. Query the Total Insight diagnostics console; if the internal Drive Gain index is steady and within nominal range, execute a standard zero-trim to eliminate thermal expansion offsets.

Request a Technical Price Quote (Within 2 Hours)A: The meter features a specialized internal geometry with an optimal slope profile that guarantees full self-draining performance when mounted vertically. With no cavities, internal pockets, or sharp step-changes in the flow path, it eliminates medium retention and ensures full cleaning compliance during standard CIP/SIP cycles.
A: Yes. Utilizing the Yokogawa Total Insight software package, the transmitter continuously maps real-time fluid density measurements against temperature profiles. This allows it to compute inline concentration outputs (such as °Brix, Plato, or custom concentration curves) directly without requiring laboratory grab sampling.
A: Absolutely. Every shipped ROTAMASS Hygienic unit is 100% factory-new and includes traceable serial numbers, standard calibration logs, original 3-A and EHEDG certificates, along with complete EN 10204 3.1 Material Test Certificates (MTC) ensuring compliance with FDA surface roughness limits.
