Automated Dosing System for Powder Ingredients

Posted in Chemical, HMI and SCADA, Manufacturing Automation and Intelligence


DMC programmed a system to control the dosing of various powder ingredients in a continuous mixing process for a major chemical manufacturer.


DMC worked with the client to replace a manual dosing system with an automated measured dosing system.  The operator enters in the ratio of each material to be mixed in the continuous process.  The PLC communicates the mass feed rates to each automated feeder via modbus.  All recipe are stored and edited using the InTouch HMI.  The feedrates are continuously monitored and logged and the operator is immediately notified of any process deviations or feeder alarms.
