FIELD OF THE INVENTION
The present invention relates to a system for automatic accountal of fluids, more particularly to accountal in storage tanks, vessels, containers or the like devices.
A BRIEF DESCRIPTION OF THE DRAWINGS
These and other aspects of the embodiments herein will be better appreciated and understood when considered in conjunction with the following description and the accompanying drawings. It should be understood, however, that the following descriptions, while indicating embodiments and numerous specific details thereof, are given by way of illustration and not of limitation. Many changes and modifications may be made within the scope of the embodiments herein without departing from the spirit thereof, and the embodiments herein include all such modifications.
Figure 1 shows the system for automatic accountal of fluids for a tank in closed condition according to embodiment of the present invention. .
Figure 2 shows the system for automatic accountal of fluids for a tank being filled according to embodiment of the present invention.
BRIEF DESCRIPTION OF THE PRESENT INVENTION
In the following brief description of the embodiments of the present invention reference is made to the accompanying figures, which in conjugation with this detailed description, illustrates and describes working principle of system for automatic accountal of fluids in a vessel, container, tank or the like.
2

For the purpose of understanding and clarity reference herein in the following description is being made to a tank containing fluids for which accountal needs to be done. However, it should be apparent to a person skilled in the art to use other embodiments pertaining to the storage of fluids other than tank, say storing in vessel, container or the like devices.
It is an object of the embodiments herein to provide a simple system for automatic accountal of fluids.
According to an embodiment herein and as referred to figure 1, system for automatic accountal of liquids in a tank may comprise of a tank having a unique identification number, an inlet pipe adapted to the tank, a cap adapted on the inlet pipe, atleast one active or passive radio frequency identification (RFID) tag RFT1 and RFT2 bearing the identification number of the tank and adapted to the inlet pipe and a cap respectively of the tank, and atleast one reader cum processor RP1 and a communicating device CD1 interconnected to each other and adapted to the tank. The reader cum processor RP1 may be connected to the communicating device CD1 for transmitting the data in the form of generate an RF signal via an RF transmitter encoding the tank identification number and related information. The RF transmitter may be configured to transmit the RF signal in the form of RF pulses to the receiver. RPs basically control, monitor and account the accountal of the liquid and signals to the receiver via communicating device.
The RP1 may have an embedded clock and continuously maintain the time log of the removal and replacement of the cap, insertion and removal of a dispenser

pipe that is explained in an embodiment as explained later in the foregoing
description
The person monitoring the accountal system may receives the signal in the meaningful information through interaction devices like PDA, mobile, computer or
any other handheld computing network having an integrated RF receiver.
The RP1 being connected to the communicating device CD1 so that in case it does not detects the presence of RF tags on the cap or the inlet pipe during the operation, an RF signal is sent to the person monitoring that may be located at a centralized place.
In another embodiment herein, signal to the receiver may be provided via a remote located server that may send the meaningful information to the person monitoring the accountal system via PDA, mobile, computer or any other handheld computing network having an integrated RF receiver.
In another embodiment herein, disposal of the fluid to the tank may be done through a dispenser as shown in figure 2. Each of the fluid dispensers may have a unique identification number embedded in a RF tag (RFT5). Each of the dispensers may have reader cum processor (RP3) connected to communication device CD2 near the outlet pipe of the dispenser. RP3 may be connected to the pump of the dispenser. Further, each of the dispensers either static or mobile may have a flow meter that may give a digital output. Necessary arrangements for power supply to the device may be provided to the various electrical and electronic equipments.

RP3 on the dispenser may have a list of valid RF identification numbers a plurality of tanks available in the system. RP3 on the dispenser reads and records the RFT2 adapted on the tank. RP3 senses the validity of RFT2 belonging to a particular tank during operation, and upon confirming it RP3 permits the pump of the dispenser to operate and fill the tank with the fluid. After filling the fluid, RP3 may register the amount of liquid dispensed and the time of dispensing. The RP3 then transmits to the communicating device CD1 provided on the tank through CD2.
Upon inserting the outlet end of the dispenser into the tank and upon filling of the tank, The RP3 sends signal corresponding to the data regarding the amount of liquid dispensed into the tank and the time to the communicating device CD1 through the communicating device CD2. The RP1 updates the data and transmits the time, amount and the details of the dispenser for accounting purposes.
In another aspect of the dispenser embodiment, herein in case the RFT2 does not belong to an authorized tank, RP3 will not permit the pump of the dispenser to operate and fill the tank with liquid.
According to another embodiment, an outlet is provided to the tank having a flow meter and a reader cum processor RP2. Further, plurality of valves is also provided at the outlet to divert the liquid as desired upon applications. Reference herein is made to two valves v1 and v2 (as shown in figure 1 and figure 2) for the sake of convenience and as illustrated in figure 1, however plurality of valves may be incorporated into the system. The valve v1 regulates the flow of the liquid
5

into a specific process while the valve v2 regulates the flow to another decanting tank. Again, here also RF signal regarding opening and closing of the valves may be send to the receiver via RP2 through communicating device CD1. Each of the decanting outlets of the tank has unique identification number embedded in RFT3 adapted on the outlet pipe of the tank.
Further, an RF tag RFT4 may also be provided on the cap of the outlet pipe. The RP2 records the amount of the liquid either decanted or pumped into the process by the position of the valves. Another flow meter is also connected to the outlet pipe of the tank. In an aspect of the outlet embodiment, in case the fluid is sent to a specific process, the RP2 having an embedded clock that continuously maintain the time log of withdrawal of the liquid and sends signal to the receiver. In another aspect incase the fluid is decanted into another tank, the RP2 senses and records the identification details of the tank and also the amount of fluid decanted. If the RP2 does not detect any tank with valid RF tag, RP2 will not allow the opening of the valves. Further, incase the valves are tampered and the fluid is decanted into an unknown tank, RP2 will then transmits a signal to the person monitoring the accountal system.
