This research book is based on a prototype built for automated filling, under filled bottles removal and capping of bottles without any human intervention. The whole process is PLC controlled. The sequence of system is to fill the bottle, then check it's level with the help of sensor and eventually cap the bottle which pass through level sensor check station. Otherwise, level sensor would discard the underfilled bottle. This prototype was built using pneumatic actuatuors, pump, direction control valves, phototransistor,conveyor belt,air compressor and mechanically fabricated mild steel structure as a platform for bottles. For readers' interest, references and helping material has been included in this publication which surely will enhance their focus and exposure in this particular area.
