FuelGenius monitoring system is a complete solution for monitoring fuel tank level at remote locations such as telecom tower sites. Generator output and status can also be monitored through MODBUS or CANBUS. Data is collected and transmitted through GSM cellular network or a wired connection to a central monitoring location. Server management software displays all sites through a mapping interface, together with current fuel level and alarms when fuel level is low warning or critical. Sudden drops in fuel level and abnormal fuel usage, such as fuel level decrease when genset is not operational, will trigger alerts and notifications via E-mail, SMS or SNMP trap allowing rapid response to the site situation.
