DESCRIPTION OF INVENTION
1. Title of Invention:
Adulteration Control Device for Retail Outlet ("ACD-R").
2. Field of Invention:
The present invention relates to adulteration control device for the retail
end,
which can be integrated with the dispatch station. The device can be used in
any
field where problem of mixing / adulteration is encountered. Particularly so
in the
field of petroleum products like mixing of non-standard products with the
standard products supplied by petroleum companies. Adulteration is a major
problem for these industries. ACD-R *addresses this problem on the retail end
very
effectively.
3. Background of the Invention:
The invention addresses the major problems of getting the information about
the
adulteration instantly i.e. on real time basis and without interference from
any
human element.
Earlier the adulteration detection was possible only by way of a lucky tip off
or by
way of reconciling historical data. The historical data can be and is
manipulated
by the interested parties and therefore the action could not be taken. Hence,
no
effective real time adulteration control system exists currently.
The invention logs all the information on the retail end and communicates it
to the
dispatch station resulting in instant information to the concerned official(s)
if there
is any adulteration material added to the storage tanks, and this it does
without any
human intervention, thus addressing the most difficult hurdles of human
manipulation, and timely information.
4. Objects of Invention:
The principle object of the present invention is to restrain and identify
cases of
adulteration and provide information to concerned officials / persons on real
time

5. A Summary of Invention:
The invention aims to restrain and identify cases of adulteration and provide
information to concerned officials / persons on real time basis by way of
continuous intelligent interaction between the retail sale point and the
dispatch
station using convergence of, instrumentation, software, hardware
telecommunicatiori technologies to achieve the desired results and keep the
system
functional on real time basis devoid of any human intervention thus
eliminating
possibility of tampering & manipulations.
Typically, the Gasoline/HSD/LDO / All Petroleum Product selling units are
known as Retail Outlets / Gas Stations / Petrol Pumps etc.
The adulteration occurs at these places by way of addition of non-standard
fuel to
the storage tank, which is later on dispensed through the dispensing unit to
the
vehicles, which come for refueling.
In principle the adulterant has to go through the storage tanks to be sold to
the
customer. Hence, we propose to control these tanks by way of convergence
technologies (Software, Instrumentation, Telecommunication etc.,) and by
connecting them with the Dispatch Station / Dispatch Location System on real
time basis to detect any non-standard product coming from the illegal source.
