Various fuel types (summer diesel, winter diesel and especially biodiesel) have different permittivity values. That explains the difference in fuel volume measurement when capacitive fuel sensors are used. For taking that differences in account, DUT-E 2Bio differential fuel level sensors is made.
DUT-E 2Bio has three measuring electrodes, what allows sensor to detect various fuel types automatically. Advantages of DUT-E 2Bio differential fuel level sensor:
automatically detects changes in fuel composition by predefined pattern
makes automatic correction and measure fuel volume precisely
detects tank fill-up and fuel draining volumes
identifies composition of fuel and indirectly evaluates fuel quality
NEW! Automatic recognition of fuel type in a fuel tank, where the sensor is installed.
DUT-E 2Bio is used as part of GPS tracking system, vehicle telematics and fuel monitoring systems or as a replacement for standard vehicle FLS.
Detection of fuel type change
Third measuring electrode of DUT-E 2Bio ensures automatic detection of fuel type change. Automatic detection of fuel type makes DUT-E 2Bio useful for preventing misuse or theft of different fuel types filled in fuel tank.
