Precise flow measurement

for coating applications

Präzise Durchflussmessung für Beschichtungsanwendungen

 

In surface coating, the exact mixing and dosing of the materials used is crucial for consistently high quality. Whether manual or automated processes - precise control of the material flow minimizes waste, reduces resource consumption and improves reproducibility. Our Rheonik Coriolis Mass Flow Meters offer maximum accuracy and process reliability, even with fluctuating viscosity of the media.

 

 

1K, 2K and 3K materials: challenges and solutions

Different coating systems are used depending on the application. Whether one-component (1K), two-component (2K) or three-component (3K) materials - each system places specific demands on the measurement technology.

1K Coating Systems: Consistent Dosing for Uniform Quality

1K coating materials consist of a single component and are ready to use. The challenge lies in uniform dosing and application, especially in applications with fine spray nozzles or low flow rates. Our Rheonik flow meters detect even the smallest flow rates with the highest accuracy and provide excellent zero stability. This allows operators to optimize material consumption and ensure a consistent coating thickness.

2K Coating Systems: Precise Mixing for Optimal Curing

 

Two-component (2K) coatings consist of a base paint and a separate hardener, which are mixed shortly before application. This places high demands on mixing and dosing technology, as the exact mixing ratio is crucial for adhesion, hardness, and durability of the coating. Rheonik Coriolis mass flow meters ensure continuous real-time measurement of both components, even with fluctuating pressures or viscosity changes. Our sensors provide:

  • High-precision dosing with an uncertainty of up to 0.05%
  • Fast response times for precise mixing
  • Maintenance-free measurement technology, as there are no moving parts
  • Assurance Factor® for continuous self-monitoring of measurement accuracy

The result: perfectly balanced mixing ratios without material waste, consistently high coating quality, and extended durability of end products.

3K Coating Systems: High Complexity – Precision Required

 

Three-component (3K) coatings extend the system with an additional component, such as a catalyst or additive mixture. This requires particularly precise control to ensure homogeneous mixing and exact ratios. Rheonik mass flow meters can also monitor complex mixing processes, ensuring consistent composition of the final formulation, regardless of temperature or pressure fluctuations.

 

Water- and Solvent-Based Coating Systems

 

Coating materials can be either water-based or solvent-based. Both systems require precise measurement and control technology to ensure optimal application.

Water-Based Coatings: Gentle and Environmentally Friendly

Water-based paints and coatings have gained importance in many industries. They offer environmentally friendly alternatives to conventional solvent-based systems. However, their flow properties often vary due to temperature changes or additives. The highly sensitive Rheonik flow meters detect even slight changes in density and viscosity and dynamically adjust the measurement to keep material dosing optimal at all times.

Solvent-Based Coatings: Control Despite Viscosity Fluctuations

Solvent-based paints and coatings often require special safety measures due to their volatile components. Our flow meters are available in a variety of exotic materials to safely measure even aggressive or corrosive media. Additionally, they are designed for high- and low-pressure applications, ensuring exact flow control even at extremely low flow rates.
