calibration management system renders the cable unnecessary

calibration management system with a traditional cabled sensor system, a trench would need to be dug in order to accommodate a cable installed at the tank and traveling back to the station's management system. Using a wireless system renders the cable unnecessary; however, the tag battery may need to be periodically replaced—typically, about once every two years, depending on the conditions around the tank and the frequency of transmissions.
automated fuel management system transmits sensor data from an underground tank to a reader installed at the ground surface via a 2.4 GHz transmission complying with the IEEE 802.15.4a standard.
