Claims

[Scope of utility model registration request]

In a carburetor that measures fuel in a float chamber and supplies it to the engine according to the air flow rate, there is a capacitance sensor that detects the liquid level in the float chamber, and a capacitance sensor that measures fuel according to the output of the capacitance sensor when the liquid level changes in the float chamber. A vaporizer characterized by being provided with a control device for controlling the supply amount.
