Abstract
A temperature compensating fuel dispenser comprises a fuel-handling compartment, an electronics compartment, a barrier separating said compartments, and at least two fuel lines in the fuel-handling compartment. Each fuel line is provided with a flow meter and a temperature sensor. The fuel dispenser has a compensator device for compensating a flow measured by the flow meters based on a temperature measured by the temperature sensors. A control unit is arranged in the electronics compartment connected to each flow meter by a respective communication line. The means for compensating the measured fuel flow comprises one compensator for each flow meter arranged in the fuel-handling compartment in connection with the respective flow meter. The communication lines are connected between the respective flow meters and the control unit through a common intrinsically safe passage in the barrier. A method for compensating a measured fuel flow for a temperature of the fuel is also disclosed.
