The Variable feeding system measures the weight by means of a load cell under the reactor scale frame to determine the weight of the material on the reactor. A digital speed sensor is mounted on the tail drum or rotating equipment and continuously measures the pulse output of the speed sensor at the feed rate, which is proportional to the screw speed. The velocity signal along with the weight signal is weighed and fed to the belt feeder controller to generate and display the cumulative/instantaneous flow rate. The feeder controller compares the flow rate to the set flow rate and the controller outputs a signal to control the inverter to achieve the dosing requirement.

Weighing Vertical reactor is an automatic production line for conveying, proportioning, heating, mixing and packaging of different types of materials (solid or liquid). It adopts PLC control mode and novel frequency conversion speed control feeding mechanism, which can realize the functions of material transmission, dosage control, formula design and production data management with the dosage control software package. And can realize the aggregate control of multiple batching systems through the network.

Weighing equipment in the production of powder and some inappropriate in the pipeline measurement of the media on the pro-measurement and control, a typical kettle weighing as an example; installed in the bottom of the kettle three weighing modules will be the kettle kettle weight signals transmitted to the junction box, the junction box will be the output of the weight module weight signals are connected in parallel to the weight terminals or weighing controllers, the weighing terminals or weight transmitter will be the weight signals are processed into the corresponding weight data. The weighing terminal or weight transmitter will process the weight signal into corresponding weight data.

The Computer weighing system is based on a load cell, and through signal amplification and a microprocessor, the weight value is converted into an electrical signal output, which can be used for data processing by a computer. It is suitable for controlling the production process with computerized technology.
