A method for automatically electronically associating vessel identity information of a vessel with an unassociated telemetric device, the method including rules relating to the operation of a system, the unassociated telemetric device comprising a processor and being configured to detect and transmit quantity or usage data and being configured with a location sensing device, wherein the unassociated telemetric device is configured to communicate with a remote server, the method comprising the steps of: the remote server receiving the vessel identity information comprising a deployment location for the unassociated telemetric device (201, 211); the unassociated telemetric (201, 211) device operating in accordance with a rule comprising an automatic action rule; in response to the unassociated telemetric device operating in accordance with the automatic action rule, the processor receiving location information of the unassociated telemetric device from the location sensing device; the unassociated telemetric device (201, 211) transmitting the location information; the remote server receiving the location information; the remote server correlating the location information with the vessel identity information when resolving that the location information represents that the unassociated telemetric device is within a proximity to the deployment location, and the remote server automatically electronically associating the unassociated telemetric device with the vessel identity information, resulting in the unassociated telemetric device becoming an associated telemetric device (12, 21), so that when the associated telemetric device generates quantity or usage information, the quantity or usage information transmitted by the associated telemetric device is applied to a data store of the remote server related to the vessel identity information. the remote server receiving the vessel identity information comprising a deployment location for the unassociated telemetric device (201, 211); the unassociated telemetric (201, 211) device operating in accordance with a rule comprising an automatic action rule; in response to the unassociated telemetric device operating in accordance with the automatic action rule, the processor receiving location information of the unassociated telemetric device from the location sensing device; the unassociated telemetric device (201, 211) transmitting the location information; the remote server receiving the location information; the remote server correlating the location information with the vessel identity information when resolving that the location information represents that the unassociated telemetric device is within a proximity to the deployment location, and the remote server automatically electronically associating the unassociated telemetric device with the vessel identity information, resulting in the unassociated telemetric device becoming an associated telemetric device (12, 21), so that when the associated telemetric device generates quantity or usage information, the quantity or usage information transmitted by the associated telemetric device is applied to a data store of the remote server related to the vessel identity information.
