Liquid Filling machine is mainly used for filling management, screen man-machine dialogue and weighing data storage and printing. With the development of microprocessor technology, the weighing instrument is used to control the Filling system of one or more materials, which can completely or partially replace the programmable controller to realize the automation of liquid filling scale and filling weighing measurement. Weighing instrument has many functions such as self-diagnosis, automatic zero tracking, zero peeling, preset point output, dynamic weighing, data communication and so on.

The automatic filling machine adopts the S7-200 PLC control system and the weighing controller to supply power to the weighing sensor/weighing module, collect small signals, amplify and then output the standard 0-5V or 4-20mA output; PLC through the standard analog module to collect signals, and then through the transformation, calibration, through the PLC man-machine interface input the corresponding parameters, through the PLC integrated digital quantity filling control, dosing and other metering tasks; Weighing instruments with analog current output are also available: The weighing control instrument directly accepts the signal of the weighing module, the weighing instrument can indicate the weight, and convert the weight value into 4-20mA signal output to the DCS or PLC signal module, and the DCS or PLC then converts the 4-20mA signal into the weight value, and is controlled by the DCS or PLC.
