Continuous Liquid Dosing

| System Structure and Operating Principle

In continuous liquid dosing systems, each liquid component is controlled independently and continuously fed into a common line:

 • Liquid tanks or feed vessels mounted on load cells
 • Gravimetric dosing operating on the loss-in-weight principle
 • Controlled flow via pumps (gear, lobe, or diaphragm type)
 • Direct feeding into the continuous mixer or process equipment

The decrease in tank weight is monitored in real time, and the pump flow rate is adjusted accordingly. This ensures that liquids are fed at the correct ratio regardless of changes in density, temperature, or viscosity.

| Loss-in-Weight Liquid Feeders and Control

VOLDE liquid loss-in-weight feeders deliver stable performance across a wide operating range, from low to high flow rates. The system detects even the smallest changes in flow and corrects dosing instantaneously.

Thanks to this structure, the ratios specified in the recipe are continuously maintained, and no dosing deviations occur during long-term operation. Low-percentage liquid additives are dosed reliably, while a constant and balanced liquid feed is maintained throughout the process

The control system manages automatic filling transitions without disrupting dosing accuracy, preserving the continuity of the continuous process.
