Gravimetric Dosing – Fast and Highly Accurate

Gravimetric Dosing
1 Oct 2025  |
In the chemical, pharmaceutical, and food industries, dosing valves are essential for handling high-value solid products continuously and with precision. These components ensure correct movement of powders, granules, and particles in sectors where quality and hygiene are critical. The Rotometering valve by SteriValves is designed for rapid and ultra-precise gravimetric dosing of powders and granules. Engineered to operate in combination with load cells, it is ideal for applications in the pharmaceutical, fine chemical, and food industries.

The system consists of two concentric dosing elements:

  • A rotor, which controls the initial product flow, and
  • A screw (auger), which ensures the final micro-dosing.

Both elements are independently driven, providing a unique combination of high accuracy without compromising discharge speed. In conventional dosing systems, higher precision often means lower throughput. Rotometering optimizes both parameters, delivering controlled and continuous product fractioning.

SteriValves’ system is based on full traceability, allowing the origin, production path, and related events of each product to be tracked. This provides added value: every product, accessory, or component can be easily identified for replacement or maintenance.

Available in ATEX-certified and FDA-compliant versions, the Rotometering valve is suitable for installations such as BIN bottoms, Big-Bag discharge, or process machinery. The auger is customizable according to product characteristics, ensuring flexibility and protection of product quality.

Rotometering represents a key technology for solid process automation, reducing manual intervention and improving operational efficiency.
