The graph shows the level in a tank that empties slowly and is then automatically refilled and also the ambient temperature at the location of the tank.
This is one example use of GeoSIMs global M2M data service. The tank level and ambient temperature are being sent real time using the local mobile phone network but without using a GPRS/data connection. GeoSIM utilises over 550 major mobile networks in 220 countries to transmit data without a GPRS connection. Data messages are a fixed price no matter where in the world the M2M device is located.
