The working principle of the chemical liquid t package weighing filling machine is the use of electronic scales measuring the characteristics of high accuracy, the electronic weight signal sensor and my company's load control instruments using the data cable to connect the pressure signal of the electronic scales in the measurement process continuously transmitted to the control instruments, control instruments to achieve preset quantitative weight control to stop the pump, close the pneumatic valve. The measurement accuracy is not the impact of factors such as density, temperature, pressure, air bubbles, simple operation, saving time, easy to install, easy to maintain. 
 Brief operating processes: 
 1, the empty ton package into the filling machine on the scale platform, tons of packages mouth at the filling mouth. 
 2, stable 0.5-2 seconds (changes in detected light does not shine), press the start button. 
 3, automatically peeled. Lift head down, the discharge port into the container open, fast filling. 
 The valve is closed, the deceleration value is reached, quick, slow filling. 
 5, when the quantitative value is reached, a gate turn off. Lift head up. 
 6, over t package repeat the steps above.
