ABSTRACT:- This paper study the conversion of the mechannical control system ton electrical control system for the softdrink machine which use gears as timers in the process of counting the number of the bottles and in the process of controlling the level of the softdrink in the bottle. The electricl control system use electronical components such as integrate circuits (counters , timers , LCD display ) , using the counter to count the number of the bottles with the use of the photosensor ( in our paper counting every four bottles )and adjusting the level of the fluid by one of the following methods. The first method of controling the level of the liquid is by the timer which is fixed at time which is required to fill the bottle to the adequate level and it is adjustable according to the volume of the bottle. The Second method for conteroling the level of the liquid is the ultrasonic device which use the ultrasonic sensor to control the level of the fluid and it is adjustable according to the distance between the sensor and the bottle. The results of the electrical and mechanical models achived the satisfication results .
