An apparatus the dispensing a liquid fuel and measuring the amount dispensed according to a temperature-corrected volumetric measure includes a housing having a fuel-handling compartment and an electronics compartment and a barrier between the fuel handling compartment and the electronics compartment, a plurality of fuel passageways through the fuel-handling compartment, each passageway having a flow meter to measure the volume of fuel flowing through the passageway and a thermometric probe adapted to read the temperature of fuel flowing through the passageway, each of the meters being connected by a first electrical circuit to pass an electrical signal representative of the volumetric flow through its respective passageway onto the first circuit, each of the probes being connected by a second electric circuit to pass an electrical signal representative of the temperature of the probe onto the second circuit, the second circuit having one intrinsically safe passage through the barrier, and electronics in the electronics compartment including a computation device connected to the circuits to receive the electric signals and to modify the electrical signal representative of the volumetric flow to account for temperature.
