Abstract

A tank level monitoring system is provided. The system comprises a monitor and a data center. The monitor is operatively connected to the tank to periodically monitor a level of product stored in the tank. The monitor includes a user-defined reporting schedule programmed therein. The data center is in communication with the monitor via a data channel. The monitor transmits level measurement information to the data center over the communication channel based on the user-defined reporting schedule.

Claims

1. A tank level monitoring system comprising:

a monitor operatively connected to the tank to periodically monitor a level of product stored in the tank, the monitor including a user-defined measurement interval and reporting schedule programmed therein;

a data center in communication with the monitor via a data channel;

wherein the monitor measures the level of product stored in the tank at a first rate based on the user-defined measurement interval and reporting schedule; and

wherein the monitor transmits level measurement information containing at least two level measurements to the data center over the communication channel at a second rate based on the user-defined measurement interval and reporting schedule, the second rate being slower than the first rate.

2. The system of claim 1, wherein the data center includes a user interface providing a plurality of user selectable scheduling options from which a user can create the user-defined measurement interval and reporting schedule.

3. The system of claim 2, wherein the data center transmits the user-defined measurement interval and reporting schedule to the monitor via the communication channel.

4. The system of claim 3, wherein the communication channel is a cellular network.

5. The system of claim 2, wherein the user interface provides user selectable scheduling options including a daily reporting option and a weekly reporting option.

6. The system of claim 2, wherein the user interface provides user selectable scheduling options including a user selectable time of first report option.

7. The system of claim 6, wherein the selectable time of first report option comprises a user selectable day of the week option and a user selectable time of day option.

8. The system of claim 2, wherein the user interface provides user selectable scheduling options including a user selectable time between reports option.

9. The system of claim 2, wherein the user interface provides user selectable scheduling options including a user selectable maximum reports per week option.

10. The system of claim 2, wherein the user interface provides user selectable scheduling options including a user selectable measurement interval option.

11. The system of claim 1, wherein the monitor stores level measurement information from periodic monitoring events taken at the first rate until the level measurement information is transmitted at the second rate based on the user-defined measurement interval and reporting schedule.

12. The system of claim 1, wherein the data center includes a user interface providing a plurality of user selectable scheduling options from which a user can change the user-defined measurement interval and reporting schedule, wherein the data center transmits the changed user-defined measurement interval and reporting schedule to the monitor, and wherein the monitor thereafter measures the level of product stored in the tank at a third rate based on the changed user-defined measurement interval and reporting schedule, and transmits level measurement information containing at least two level measurements to the data center at a fourth rate over the communication channel based on the changed user-defined measurement interval and reporting schedule, the fourth rate being slower than the third rate.

13. A method of scheduling transmission of tank level measurement information from a tank level monitor to a data center via a communication channel, the method comprising the steps of:

receiving a user input defining a measurement interval and reporting schedule containing a first rate which tank level measurements are to be taken and a second rate at which tank level measurement information containing tank level measurements taken at the first rate is to be reported, the first rate and the second rate being different;

transmitting the measurement interval and reporting schedule to the tank level monitor; and

receiving tank level measurement information containing the tank level measurements taken at the first rate based on the measurement interval and reporting schedule transmitted from the tank level monitor at the second rate in accordance with the measurement interval and reporting schedule.

14. The method of claim 13, further comprising the step of displaying a user interface providing a plurality of user selectable scheduling options from which a user can create the measurement interval and reporting schedule.

15. The method of claim 14, wherein the step of receiving a user input further comprises the step of receiving a selectable time between reports parameter.

16. The method of claim 14, wherein the step of receiving a user input further comprises the step of receiving a maximum reports per period parameter.

17. The method of claim 14, wherein the step of receiving a user input further comprises the step of receiving a measurement interval parameter.

18. The method of claim 14, further comprising the step of displaying the transmission schedule on the user interface.

19. A method of monitoring a product in a tank, comprising the steps of:

receiving a user defined measurement interval and transmission schedule;

monitoring a parameter of the product in the tank at a first rate defined in the user defined measurement interval and transmission schedule; and

transmitting at a second rate information related to a plurality of the parameters monitored at the first rate in accordance with the user defined measurement interval and transmission schedule.

20. The method of claim 19, further comprising the steps of:

receiving an updated measurement interval and transmission schedule;

monitoring the parameter of the product in the tank at a third rate as defined in the updated measurement interval and transmission schedule; and

transmitting at a fourth rate information related to a plurality of the parameters monitored at the third rate in accordance with the updated measurement interval and transmission schedule.
