Apparatus and method for delivering liquids

A liquid delivery apparatus equipped with a liquid delivery line which can deliver liquids different from each other in a property such as density, viscosity, or the like,

• wherein a flow regulation means is provided in said liquid delivery line, said flow regulation means comprising:
• a body having an inflow port into which said liquid flows and an outflow port out of which said liquid flows;
• rotators rotatable within the body to move said from said inflow port to said outflow port by given volumes along the internal wall of said body and to continuously deliver said liquid from said outflow port to said liquid delivery line and a drive unit for driving said rotators,
• wherein said drive unit comprises;
• a drive motor for driving said rotators;
• and a control unit for controlling current to said drive motor so that said rotators rotate at a speed corresponding to the property of said liquid.
