Acoustic alarm device for indicating the decrease in pressure of a tank by a predetermined value comprising a valve adapted to be closed by the gas pressure, an impeller forced by a spring and adapted to open the valve, and a body producing sound that responds to the gas in the tank characterized by the fact that the impeller is constructed in the form of a piston slidable in the spring chamber so that it closes it tightly for the passage of gas coming from the chamber or compartment of the valve, enabling a passage between the upper and lower face of the piston adapted to admit only the amount of gas needed for the operation of the alarm apparatus.
