Compensating for surface movement of liquid product within one or more liquid product tanks during capture of height and volume data
First Claim
1. A method of filtering physical volume measurements within a tank at a point in time, the method comprising:
- receiving a plurality of measurement data at a plurality of times, each measurement data representing a volume of liquid product within the tank;
comparing each volume of liquid against at least one predetermined volume identified as being unreliable;
generating a second set of measurement data by eliminating any measurement data from said plurality of measurement data that is identified. as being unreliable;
determining a sample mean and a standard deviation for said second set of measurement data; and
filtering said second set of measurement data to generate a third set of measurement data by eliminating any measurement data from said second set of measurement data that has a value plus or minus a predetermined number of said standard deviations from said standard mean.

Abstract
Disclosed are systems, methods, and computer program products to compensate for surface movement of liquid product within one or more tanks during a liquid product book to physical reconciliation process. A plurality of measurement data at a plurality of times can be received. Each measurement data represents a volume of liquid product within the tank. The volume of liquid product represented by the measurement data can be compared against at least one predetermined volume identified as being unreliable. Following eliminating the measurement data that is unreliable, a sample mean and a standard deviation for the remaining measurement data are calculated and then used to filter the remaining measurement data by eliminating any measurement data that has a value plus or minus a predetermined number of the standard deviations from the standard mean for the second set of measurement data.

10. A method of filtering physical volume determinations within an inventory tank at a point in time, the method comprising:
-
receiving a measurement data at a plurality of times, said measurement data including data representative of a temperature of liquid product within a tank and a volume of the liquid product within said tank;
comparing each volume of liquid against at least one predetermined volume identified as being unreliable;
generating a second set of measurement data by eliminating any measurement data from said measurement data that is identified as being unreliable;
determining a sample mean and a standard deviation for said second set of measurement data; and
filtering said second set of measurement data to generate a third set of measurement data by eliminating any measurement data from said second set of measurement data that has a value plus or minus a predetermined number of said standard deviations from said standard mean. - View Dependent Claims (11, 12, 13)

14. A method of filtering physical volume measurements of a liquid within a tank made at a plurality of times to compensate for waves motions within the tank, the method comprising:
-
receiving, at a centralized management system, a measurement data for a plurality of times, each measurement data representing a volume of liquid product within the tank;
comparing each volume of liquid against at least one predetermined volume;
generating a second set of measurement data by eliminating from said measurement data any data corresponding to said at least one predetermined volume;
determining a sample mean and a standard deviation for said second set of measurement data; and
filtering said second set of measurement data to generate a third set of measurement data by eliminating any measurement data from said second set of measurement data that has a value that is more or less than a predetermined number of said standard deviations from said standard mean. - View Dependent Claims (15, 16, 17, 18)
