Details:

The 8240 Tactical Data Unit (TDU) collects pressure, temperature and flow measurements from connected field devices, such as the Varec 7660 Tactical Fuel Gauge (TFG) or a Tactical Flow Meter (TFM). It calculates observed fuel volumes and performs the collapsible tank mapping process. All data is transferred to the TacFuels Tactical Mobile Computer for inventory management and accounting.Specifications
