ABSTRACT:
A saucepan capable of setting amount of soup finally left therein, including a body having a nozzle portion communicated with inner portion thereof, and a cap provided with pressure-relieving hole and pressure valve, wherein a conduit provided with scale is extended into the nozzle portion and the position of lower opening of the conduit will determine the final level of the cooked soup, a thermal sensor being disposed at upper end of the conduit whereby when the cooked soup goes down below the lower opening of the conduit, because the pressure limit of the pressure valve is larger than the pressure existing in the conduit, the created steam will immediately alteratively escape through the conduit and the thermal sensor will sense the temperature of the escaping steam and indicate the controller to cut off power and emit warning sound so as to effectively control final amount of the soup left in the saucepan.
