Constant monitoring
Gravimetric control system (GCS) constantly monitors the raw material consumption (for example for the pipelines the mass flow [kg/h] and the metric wight [kg/m]) and compares it to the haul-off speed [m/min]. If any deviation of the actual metric weight from its calculated value occurs, the Gravimetric Control Systems corrects the parameter to the set point.
According to the customer's demand and requirements the Gravimetric Control Systems instrumentation and software are delivered as following packages:
1-10-flow monitoring
Basic Gravimetric Control Systems compromises the following components:
Feed hopper
Weighing hopper
Metering valve and frame
PLC single user interface
Optional software for raw material recipe management including necessary number of recipe memory locations.
Line speed measurement with closed loop control
Screw rotary speed measurement
Measurement of screw output per one round
Interfaces for upper level control and printer (optional)
