14. A method of detecting theft of a product stored in a storage tank, comprising the steps of:
-
inputting an activation time, a deactivation time, and a threshold level of change;
receiving information from a tank level monitor relating to a level of the product in the tank;
monitoring the information after the activation time and before the deactivation time; and
generating an alarm signal when a change in the monitored level of the product in the tank has dropped by the threshold level of change to indicate that the theft of product has been detected. - View Dependent Claims (15, 16)

17. A method of detecting a theft of product from a storage tank, comprising the steps of:
-
receiving a user input defining an activation period;
receiving product level information from a tank mounted monitor during the activation period; and
generating an alarm signal when a change in the monitored product level in the tank has at least reached the threshold level of change to indicate that the theft has been detected. - View Dependent Claims (18, 19, 20)
