【0042】

When the power is turned on, the controller 15 of the in-vehicle device 12 performs various initialization processes (step S1). Next, the controller 15 determines whether or not the IC memory card 11 is installed (step S2), and if the IC memory card 11 is not installed, the controller 15 enters the standby state (step S2; No).

Further, it is assumed that the flow rate of fuel per output pulse of each flow rate sensor is 0.002 (litter), and the period of the pulse from the flow rate sensor is measured in units of 1 [msec]. Assuming that the fuel consumption per hour is Pt and the pulse intervals (cycles) of the pulses PP1 and PP2 to be measured are t1 + t2 as shown in Fig. 6, Pt [litter / h] = 0.002 / (t1 + t2) x 1000 x 3600 = 7200 / (t1 + t2) Can be obtained at.

【0048】
