ABSTRACT:
A wireless tank level monitoring system is provided. The system includes a transmitter that is located in close proximity to the storage tank. The transmitter is coupled to a remote-ready tank level gauge, which provides a ratio-metric voltage output proportional to the liquid volume inside the tank. The transmitter periodically monitors the output from the level gauge and transmits the information to a base station located remotely from the storage tank. The base station displays the tank level numerically in percent full, graphically with a bar chart, or both. A conspicuous visual indication is provided by the base station when the tank level drops below a predetermined set point. In battery powered applications, the base station also reads and provides a visual indication of a low battery condition for both the transmitter and base station.
