PURPOSE: To improve the confirmation which is not affected by circumstance, by detecting the liquid level to report a corresponding quanitity of liquid by voice.
CONSTITUTION: When a vessel is full of the liquid, a high-level signal is inputted to address input terminals A3WA0 of a voice synthesizing integrated circuit 5, and a voice output word is selected and designated by this signal. When the liquid level exists between electrodes 1b and 1c, a low-level signal is inputted to input terminals D1 and D2, and consequently, outputs of output terminals Q1 and Q2 is reduced to low-level and are inputted together with high-level outputs of output terminals Q3 and Q4 to terminals A3WA0, and a voice output word is selected and designated. Thus, words "Full", "Sufficient", "About half", "Little, Please supply", "Empty", etc. are voiced in accordance with the quantity of the liquid to report the quantity of the liquid.
