The Weight Flow Regulator is a state‐of‐the‐art machine that represents a revolutionary system for instantaneous measurement and direct weighing, during the flow of product. It consists of a metal box in which the product flows, a lid and a control unit which includes a weighing disc and an electronic device for the control and programming of the machinery. The opening of the lid, electronically controlled, allows the product to escape onto the weighing disc. If the lid reaches its maximum opening limit, the alarm is automatically activated.
