**An accurate, ergonomic, flexible and secure solution for loss in weight feeders**

The flow controller controls a continuous discharge of material from a feeder at a defined flow rate.

The process is start by a simple entry of the desired flow rate (kg/min). The process can be start by a pre defined values from the table.

During operation the display informs the operator about the current flow rate, the control output of the feeder (frequency of the motor in Hz), the net weight of the hopper, the total quantity of material discharge.

__Mass flow regulation with closed loop__: The Flow controller is an application for control of constant material flow rate. The flow rate is calculated from the weight change in the batch hopper by means of statistic functions. A PID – controller determines a control output value from actual flow rate and flow rate set point. This value controls the discharge system via an analog output.
