Composition and principle of liquid filling machine
The liquid filling machine can control multiple filling machines at the same time, thus greatly reducing the cost of filling machines. It has the mechanism of mutual monitoring between computer and weighing instrument and various alarm mechanisms. Even in the case of computer crash, the filling system will not only send out alarm signals, but also continue to operate according to the original state.

Liquid material batching system based on Kingview
The batching system provides three different raw materials for the materials. The injection process is divided into three positions: low, medium and high. In actual applications, the number and high and low positions of the liquid level sensors can be changed at any time according to different process requirements.The core part of the feeding system is Siemens 57-200 PLC. The monitoring system software PLC developed by KingView is responsible for collecting input signals and issuing control commands to the auction agency after being processed by the program.The PIC and the host computer are connected through a communication electric field, and the input signal is transmitted to the PLC at the same time.The PC will also obtain the data and display it synchronously through KingView.
