When the refueling hose 14 further rises and the nozzle valve 15 reaches the desired standby position, an off signal F is introduced from the cam switch 22 to the motor control circuit 25, the drive signal C disappears, and the motor 21 and hose processing device 13 are reversed. stops, and the refueling hose 14 also stops.

When the daily display switch 18 is pressed at the time of closing or opening, the switch 18 issues a display signal L to the counting circuit 29, and a counting signal J is transmitted from the counting circuit 29 to the display meter drive circuit 30. The driving signal K causes the display meter 24 to display the sum of the daily oil supply amount (daily oil supply amount) of the oil supply device in question, which is stored in the circuit 29.

On the other hand, when the total display switch 20 is pressed, the display signal N is sent from the switch 20 to the counting circuit 28.
The count signal J of the counting circuit 28 is introduced into the display meter driving circuit 30, and the display meter 24 is input to the circuit 2.
8 displays the total amount of oil supplied to the relevant oil supply device (total amount of oil supplied).

The worker only needs to record the daily oil supply amount and total oil supply amount displayed on the oil supply display meter 24.

If the daily zero switch 19 is pressed, the reset signal M is introduced from the switch 19 into the counting circuit 29, and the 1 stored in the counting circuit 29 is
Returns the daily refueling amount value to zero.

A counting circuit is provided to store the daily oil supply amount and total oil supply amount, and by pressing a switch, the memorized values of the counting circuit are aggregated daily or in total and displayed on the oil supply amount display meter. In order to check the amount of oil supplied, it is sufficient to look at the oil amount display meter instead of going to an inconvenient place such as a pump room as in the conventional case, which saves time and is easy to see.

Furthermore, since an existing indicator is used without providing a special counter, it can be manufactured at low cost.
