This Case Study describes a solution for monitoring diesel tanks at remote locations. The solution is based on a smart level sensor at each field site and web monitoring software.
The sensors measure level and calculate volume of the diesel in liters. This information is transmitted by SMS or GPRS over a GSM cellular network. Additional information is transmitted including temperature at the site, cellular signal strength and battery voltage as applicable.
Web monitoring software allows any authorized user utilizing standard web browsers to view the state of each tank and the overall inventory.
In addition to periodic inventory reports, the smart sensor detects events such as theft and refill and immediately reports these events. The web monitor can be configured to send mail alerts to report these events.
