of the rather major reasons, which
prompted us to develop the SMART OIL
DISPENSER, is that in present Oil
Dispensing system – all operations
are performed manually and it has
many disadvantages. The customer remains
highly dissatisfied, as there is a
feeling that they get less quantity
of Oil than the money they have paid
for. Moreover it is very difficult
to control the flow of oil to the
accurate quantity, especially during
the peak hours. Many times the quantity
delivered is more than the quantity
required. This causes loss to owners
of the petrol pumps. This leads to
dissatisfaction amongst customer as
well as owners. SMART OIL DISPENSER
overcomes this problem and ensures
that the correct quantity is accurately
dispensed and leaves no room for any
kind of manual errors. The basic idea
is to have a system consisting of
a keyboard and a measuring unit. The
keyboard is used to enter different
data like rates of oil and the quantity
of oil required. The system takes
over the charge of an attendant as
soon as the required quantity is entered
and delivers the accurate quantity
of oil. Oil-flow is incremented with
quantity of oil and its amount is
also calculated as well as displayed
on the display.
