Abstract: A method of generating revenue for monitoring of a fluid dispensing system is provided. The method comprises providing a manually initiated cleaning system that cleans the fluid dispensing system. The cleaning system is manually initiated by a user of the cleaning system in response to the user of the cleaning system or a user of a monitoring system receiving a notification transmitted by the monitoring system. The method also comprises receiving fees on a periodic basis from the user of the monitoring system thereby generating revenue. The generated revenue is dependent on detected various conditions within the fluid dispensing system thereby providing sufficient and ongoing incentive for users to maintain cleaner lines in order to avoid higher monitoring costs resulting in safer fluid consumption. Alternatively, the manually initiated cleaning system may be replaced with an automated cleaning system.
