System for delivering propane or other consumable liquid to remotely located storage tanks
First Claim
1. A system for coordinating the delivery of a consumable liquid to two or more remotely located storage tanks at several different locations comprising:
- at least one monitoring unit associated with each storage tank to be in close proximity to the storage tank and communicatively linked with a sensor that provides fluid level information indicative of the amount of fluid in the storage tank, wherein each monitoring unit includes at least one processor to receive and process the received fluid level information;
at least one central server remotely located from the two or more storage tanks to be communicatively linked with each monitoring unit;
wherein each monitoring unit is capable of processing fluid level information to determine whether a predefined out-of-ordinary event has occurred and, if so, send notice to the at least one central server; and
the at least one central server to process received fluid level information (i) to provide displayable fluid level data, (ii) to forecast future fluid levels utilizing at least stored fluid level data, (iii) to determine a delivery schedule based at least on tank capacities, fluid levels, and an inventory of one or more delivery vehicles, and (iv) to provide one or more routes for the delivery vehicles to reach the storage tanks based at least on tank location and an amount of fluid to be delivered.

Abstract
An improved system for delivering propane or other consumable liquid to remotely located storage tanks including a novel combination of remote monitoring of customer tanks and an improved method of using the remote monitoring data to optimally schedule deliveries, improve safety, and more efficiently operate a propane dealership. More accurate and timely information concerning the status of customer tanks serves to improve operational efficiencies and increase safety. Data received from remote sensors can be collected and organized so that it is easily understood and utilized through the implementation of a user interface accessible via the Internet that allows the information to be presented in an efficient graphical and contextual fashion. Operational efficiencies can also be improved by taking historical propane usage for each tank, weather conditions, and projected fuel usage into account. The system can calendar required inspections of customer tanks, homes, and appliances, and data can be combined with accounts receivable information. Remote monitoring of customer tanks can be combined with other products using similar equipment to provide additional non-seasonal revenue streams.

21. A system for coordinating the delivery of propane to two or more remotely located storage tanks at several different locations via delivery vehicles, comprising:
-
at least one monitoring unit associated with each storage tank to be in close proximity to the storage tank and communicatively linked with a sensor that provides fluid level information indicative of the amount of propane in the storage tank, wherein each monitoring unit includes at least one processor to receive and process the received fluid level information;
at least one central server remotely located from the two or more storage tanks to be communicatively linked with each monitoring unit;
one or more secondary sensors capable of detecting local temperature, the presence of propane gas, or higher than normal levels of carbon monoxide and transmitting a detection signal to at least one monitoring unit;
wherein at least one monitoring unit is capable of (i) processing propane level information to determine whether a predefined out-of-ordinary event has occurred and, if so, sending notice to the at least one central server, (ii) receiving a detection signal from a secondary sensor, processing the signal to determine whether the value is outside a predetermined range and, if so, sending data concerning the detection signal through a communications link to the central server;
the at least one central server to;
(a) process received propane level information to provide displayable fluid level data, (b) forecast future propane levels utilizing at least stored historic propane level data, (c) determine based at least upon propane level information from remotely located storage tanks and maximizing the number of propane gallons delivered per mile traveled by delivery vehicles (i) an optimum delivery schedule also based at least on tank capacities, propane levels, and an inventory of one or more delivery vehicles, and (ii) one or more optimum routes for the delivery vehicles to reach the storage tanks also based at least on delivery vehicle capacity, tank location, and an amount of propane to be delivered;
a graphical user interface connected to the at least one central server via the Internet and configured to allow user input and to download information to be displayed so that (i) information concerning propane level data is organized and displayed graphically, (ii) information is at least displayed as a tank inventory listing customers and corresponding propane levels with levels above or below predetermined thresholds color-coded so that particular propane ranges can be easily identified, and (iii) alarm messages are displayed whenever a remote monitoring unit has notified the central server that a predefined out-of-ordinary event has occurred or that a secondary sensor has detected a value is outside a predetermined range.
