Walsn UniMass Coriolis Mass Flowmeters for Pilot-Scale R&D Systems

In the pilot stage, the core requirement is to measure micro-flow feed accurately and stably, so that research conclusions are based on reliable measurement data.

Why Micro-Flow Feeding Is Difficult to Measure

New material pilot testing is a critical stage for process route validation and formulation parameter iteration. These systems typically operate at low flow rates with narrow process windows. Even minor fluctuations in feed metering can interfere with the reaction and compromise the reliability of experimental data.

For micro-feed applications, flowmeters must deliver high zero-point stability, excellent repeatability, and strong resistance to vibration.

To meet these low-flow precision requirements, the Walsn UniMass series of mass flowmeters offer a 0.5 mm diameter option. Using the Coriolis principle, it directly measures mass flow while simultaneously capturing density and temperature — without additional temperature or pressure compensation. It maintains stable performance in the low-flow range and provides continuous, traceable records of feed ratios to support experimental comparison and process optimization.

Key Product Features for Pilot-Scale Integration

Micro-bore options matched to micro-feed conditions
The 0.5 mm size is specifically designed for laboratory and pilot-scale low-load feeding. It is ideal for micro-dosing of monomers and additives in synthesis research systems.

Stable measurement repeatability
Research trials depend on the comparability of multi-batch data. UniMass delivers consistent output in the low-flow range, minimizing metering-related experimental deviation and preserving the value of process comparisons.

Compact design for skid-mounted integration
The streamlined construction is well suited for package systems. System integrators can easily embed the meter into process units, fitting the limited space of pilot platforms and enabling coordinated operation with reactors and dosing systems.

Selection note: Micro-bore tubes are more susceptible to blockage and higher pressure drop. Pre-filtration and system pressure-drop calculation are recommended to ensure long-term stable operation.

Standardized documentation
Factory calibration records, material certificates, and calibration certificates are supplied to unified quality standards, helping system integrators complete package commissioning and acceptance efficiently.

Typical Application Scenarios

· Micro-feed metering on new material pilot plants

· Precision ratio control in fine chemicals and specialty synthesis

· Fluid measurement support for skid-mounted R&D test platforms

Successful commercialization of new material processes relies on continuous trial-and-error and validation at the pilot stage. Unlike production systems, the priority here is accurate and stable measurement of micro-flow feeds, ensuring that research conclusions rest on trustworthy data.

The UniMass series is suitable for single-phase, clean fluid applications. For streams containing gas or prone to condensation, selection should be confirmed with the Walsn technical team based on actual operating conditions.

Walsn collaborates closely with system integrators, providing UniMass micro-bore mass flowmeter solutions to support fluid measurement and control in new material R&D projects and help process solutions complete validation successfully.
