Abstract:
A simple automated device have been designed and constructed in order to release a
predetermined amount of liquid from a container. This preliminary study indicates that the
device releases water with an accuracy of ± 0.2 ml and 92% of the time the accuracy is
within ± 0.1 ml. The volume of the water released could be adjusted to any predetermined
value. It could fill a 500 ml water bottle in about 25 s. The device could be used for other
liquids with low viscosity. This could be modified and used for many applications ranging
from small-scale shops selling any kind of liquid by volume to large-scale industries such
as bottling any liquid. The accuracy could be improved further. The main advantage is that
the device can be easily manufactured locally at low cost.
