- the notification unit 21B sets the value obtained by adding 1 to the determination number N as a new determination number. In the second determination, since the value of the determination count N before addition is 1, the determination count N after addition is 2.
- step S114 No
- the liquid decrease amounts ⁇ G and ⁇ G ′ are smaller than the liquid decrease amount threshold value ⁇ Gc twice in succession. Don't be.
- the notification unit 21B when the liquid decrease amounts ⁇ G and ⁇ G ′ are equal to or larger than the liquid decrease amount threshold value ⁇ Gc twice in a plurality of consecutive determinations, the notification unit 21B generates abnormality information and notifies To do. For this reason, if ⁇ G ′ ⁇ Gc (No in step S114), in step S121, the notification unit 21B turns ON a determination end value STAN7 indicating the end of the process of detecting an abnormal decrease in the liquid in the tank.
- the abnormal decrease in the liquid in the tank between the first timing and the second timing judges that it did not occur. That is, if the liquid reduction amount ⁇ G, ⁇ G ′ is equal to or larger than the liquid reduction amount threshold value ⁇ Gc twice in succession, that is, if the comparison determination result is not abnormal determination twice in succession, an abnormal decrease in the liquid in the tank occurs. It is assumed that the reliability of the judgment that it is possible cannot be guaranteed. For this reason, the alerting
- the determination value BV is set to FALSE, and the process for detecting an abnormal decrease in the liquid in the tank ends. That is, the notification unit 21B does not generate abnormality information and does not perform notification. In this embodiment, it is determined that the liquid reduction amounts ⁇ G and ⁇ G ′ are smaller than the liquid reduction amount threshold ⁇ Gc twice in succession, in other words, the liquid reduction amounts ⁇ G and ⁇ G ′ are the liquid reduction amounts twice in succession. Since the abnormality information is generated on condition that it is equal to or greater than the threshold value ⁇ Gc, it can be more reliably determined that the abnormal decrease of the liquid in the tank has not occurred.
- step S108 the calculation unit 21A determines the remaining amount information (F2 ′′) at a timing different from the timing at which the liquid reduction amount ⁇ G to be compared with the second timing and the second liquid reduction amount threshold ⁇ Gc is obtained. , A2 ′′).

- the liquid decrease amount ⁇ Gf ′′ is F1-F2 ′′
- the liquid decrease amount ⁇ Ga ′′ is A1-A2 ′′.
- step S123 the notification unit 21B of the processing unit 21 illustrated in FIG. 3 compares (comparison determination) the liquid decrease amount ⁇ G ′′ with the liquid decrease amount threshold value ⁇ Gc that is the second threshold value.
- the comparison determination result is an abnormality determination, that is, when ⁇ G ′′ ⁇ ⁇ Gc (step S123, Yes)
- step S124 the notification unit 21B terminates the process of detecting an abnormal decrease in the liquid in the tank.
- the determination end value STAN7 shown is turned ON, and the determination result STAN2 in the second determination of the liquid decrease amount ⁇ G ′ is turned ON.
- the determination result STAN2 is ON, it indicates that ⁇ G ′′ ⁇ ⁇ Gc in the third determination of the liquid decrease amount ⁇ G ′′. That is, it indicates that the comparison determination result is an abnormality determination.
- step S125 the notification unit 21B sets the determination value BV to TRUE, and in step S126, generates the determination value BV that is TRUE as abnormality information, and transmits it to the monitor 26 shown in FIG. 3, for example. Or sending the abnormality information to the management apparatus 10 shown in FIG. With this notification, the process of detecting an abnormal decrease in the liquid in the tank is completed.
- step S123 when the comparison determination result is a normal determination, that is, when ⁇ G ′′ ⁇ Gc (No in step S123), the liquid decrease amount ⁇ G ′ is equal to or larger than the liquid decrease amount threshold value ⁇ Gc in the second determination. However, in the third determination, the liquid decrease amount ⁇ G ′′ is smaller than the liquid decrease amount threshold value ⁇ Gc.
- the notification unit 21B when it is an abnormality determination, the notification unit 21B generates and notifies abnormality information.
- ⁇ G ′′ ⁇ Gc step S123, No)
- step S127 the notification unit 21B turns ON a determination end value STAN7 indicating the end of the process of detecting an abnormal decrease in the liquid in the tank.
- step S1208 the notification unit 21B sets the determination value BV to FALSE. That is, the notification unit 21B does not generate abnormality information and does not perform notification.
- the determination value BV is set to FALSE, and the process for detecting an abnormal decrease in the liquid in the tank ends.
