Automatic delivery/drain detection using a level monitoring system
First Claim
1. A system for monitoring a level of product in a tank to detect at least one of a delivery and a drain operation, the system comprising:
- a monitor operably coupled to the tank, the monitor adapted to detect the level of product in the tank at a first rate and at a second rate; and
a data center in communication with the monitor, the data center adapted to receive a user inputtable threshold level of change; and
wherein the monitor detects the level of product in the tank at the first rate until the threshold level of change is detected whereupon the monitor detects the level of product in the tank at the second rate; and
wherein the data center generating an alarm signal to indicate that at least one of the delivery and the drain has occurred.

Abstract
A system for monitoring a level of product in a tank to detect one of a delivery and a drain operation is provided. The system comprises a monitor and a data center. The monitor is operably coupled to the tank and adapted to detect the level of product in the tank at a first rate and at a second rate. The data center is in communication with the monitor and adapted to receive a user inputtable threshold level of change. The monitor detects the level of product in the tank at the first rate until the threshold level of change is detected. Thereafter, the monitor detects the level of product in the tank at the second rate. The data center generates an alarm signal to indicate that one of the delivery and the drain has occurred.

6. A method of detecting at least one of a delivery and a drain of product in a storage tank, the method comprising the steps of:
-
monitoring at a first rate a product level in the tank;
determining that at least one of the delivery or drain of product has begun;
monitoring at a second rate the product level in the tank;
determining that the at least one of the delivery or drain of product has ended; and
transmitting information related to an amount of product delivered or drained during the at least one of the delivery or drain of the product. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16)

17. A method of detecting at least one of a delivery and a drain of product to and from a storage tank, the method comprising the steps of:
-
displaying a user interface having user selectable options presented thereon;
receiving at least one of a delivery function selection and a user drain function selection;
receiving a user input threshold level of change for the at least one of the delivery function selection and the user drain function selection;
initiating tank level monitoring at a first rate until the at least one of the delivery or drain functions is detected;
initiating tank level monitoring at a second rate until the at least one of the delivery or drain functions has ended; and
providing an alarm to indicate that the at least one selected function occurred. - View Dependent Claims (18, 19, 20)
