A liquid level detection section 1 that sequentially outputs liquid level data according to the liquid level, and liquid level data from the liquid level detection section 1, -
An averaging circuit 5 that removes the average value per predetermined number of samples and outputs an average value monitor compares the liquid level data with the average value data, and calculates the difference between the two as a predetermined value. A first comparator circuit 8 outputs a first control signal when supinating, and is controlled by the first control signal, and detects the liquid level during normal times when the first control signal is not input. The liquid level data from the liquid level detection unit 1 is supplied to the averaging circuit 5 without modification, and when the first control signal is input, the liquid level data from the liquid level detection unit 1 is combined with the averaged level data from the liquid level detection unit 1. After correcting the difference from the value data to fall within the predetermined range. -, a data correction circuit 9 that supplies the averaging circuit 5, a storage circuit 10 that sequentially stores the latest average value data from the averaging circuit 5, and from the averaging circuit 5; Every time the latest average value data is output, the magnitude relationship between the latest average value data and the previous average value data stored in the storage circuit 10 is compared, and when the former exceeds the latter, the second average value data is outputted. The first to output the control signal. Selecting and outputting the latest average value data from the comparing circuit 11 of No. 2 and the averaging circuit 5 of the normal time zone 1 which is controlled by the second control signal and in which the second control signal is not input; When the second control signal is output, the switching circuit 12 selectively outputs the average value data stored in the storage circuit 10, and the average value data selected by the switching circuit 1.2 is output. A residual liquid amount measuring circuit characterized in that it serves as a measurement output. ---
