A remote tank level monitoring system for a storage tank having an existing float-based level gauge features an image capturing device and communications device. The image capturing device is arranged to capture digital images that are taken over time and each include a digital representation of at least a part of the upright gauge that includes a position at which the level indicator is situated at a respective point in time at which the digital image is captured. The communications device is cooperatively linked to the image capturing device to receive image data therefrom and transmit the image data over a communications network to enable viewing of the digital representation from a remote location to check the content level of the tank as measured at the respective point in time.
