Fuel monitoring system monitors and provides real time information on the Diesel Generator’s (DG) fuel consumption, DG run hours, refilled liters, DG running status and DG battery voltage. The system collects all the data and reports the same to the application server at a centralized location. The system sends SMSs to the field staff on occurrences of various alarms. The operators can then log onto the web application and view all the parameters and create reports, from anywhere and anytime. Typical reports include alarm status, fuel and maintenance reports.
