Rotometering
Sterivalves’ Rotometering is an advanced solution designed to operate in combination with load cells, ensuring fast, precise, and accurate gravitational dosing of powders and granules.
This valve consists of two concentric dosing elements: a rotor and a screw conveyor (auger), both independently driven. The rotor manages feeding and flow control, while the auger performs the final micro-dosing, ensuring ultra-precise product transfer and optimizing the packaging process.
Rotometering is a highly versatile valve, with its fine dosing element (auger) customizable according to the specific characteristics of the handled product.
Available in an ATEX-compliant version, it ensures safe and efficient use even in potentially explosive environments and complies with FDA directives, guaranteeing high safety standards for contact with food and pharmaceutical products.
