DUT-E fuel level sensor is used for accurate fuel level and volume measurement in tanks of vehicles and stationary units. DUT-E allows determining current fuel volume and change in volume (refueling or draining) of fuel in the tank. DUT-E is used in GPS tracking and vehicle telematics systems as additional fuel sensor or as a replacement of standard built-in (factory) fuel level sensor. When used as a part of telematics system, DUT-E  allows getting reliable and accurate information on current fuel volume in the tank and to reveal misuse and fuel theft from tank. DUT-E also gives a general overview on fuel usage by vehicle or stationary unit.
