Application area:
FWG filling machine is mainly used for filling coating, ink,, paint, glue, lubrication in the field of oil industry, fine chemicals
Principle：
FWG filling machine (Semi-automatic filling machine) adopts gravimetric method to measure, by weighing sensor output signal to control the charging valve opening, so as to realize the purpose of automatic filling. By equipped with a pump in the front end of the feeding port, or pressuring the material from tank to the filling machine. The filter device can be added before filling to guarantee the quality of products. The equipment has advantages of high filling efficiency and small filling error. 
Characteristics:
1)It adopts gravimetric filling with high measuring precision and can’t be influenced by material.
2)Fast and slow feeding valves, promoting filling speed and precision greatly.
3)Wide measuring range and the accuracy is +-10g/barrel.
4)Filling nozzle adopts anti-leak device, air-free in the filling material.
5)Automatic feeding and filling, equipped with pneumatic nipping and capping set.
