Flow controllers with regulation

An accurate, ergonomic, flexible and secure solution.

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

The process is started by simply entering the desired flow rate (kg/min). The process can be started using 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 to control a constant flow rate of material. 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 the actual flow rate and flow rate set point. This value controls the discharge system via an analogue output.

The flow controller can be used in different applications:

Volumetric mode with measurement of the material flow rate.
Controlled material flow rate with local flow set point
Controlled material flow rate with stop at set point

Automatic refill during material flow: With discharge weighing, the hopper can be filled automatically. A continuous “infinite” material flow can be generated by automatic refiling.

Independent control of up to 8 feeders with MCPI Multi flow-controller
