The CentriFeeder with Integrated Control Valve (ICV) is both a controlled feed device and a mass flow measurement device in a single multi-functioning unit that will accurately measure and control the flow of any dry, free-flowing solid. Using a highly customizable touch screen HMI equipped with an integrated servo (low rpm, AC, Brushless), a PID control loop is established to control the ICV feeding the patented CentriFlow meter. For precise measurement and control, an integral linear position sensor is used to regulate the blade’s position to within 1 part in 1000 (based on stroke). For delicate products, the CentriFeeder with ICV is equipped with a Virtual Flow Stop function that stops flow with virtually no damage to your product. The outcome is an easily maintained, consistent flow that can, under some conditions, be controlled over a 100:1 range for batching, blending and ratio-control applications.
