description The invention discloses a flowmeter signal simulation method. A hardware circuit is used for simulating output signals of an entity flowmeter. The flowmeter signal simulation method comprises following steps that: a power supply transformation chip is connected with an external power supply; work parameter and simulation parameter setting is performed on a CPU chip; the CPU chip outputs simulation signals according to the simulation parameters; and a communication chip outputs the simulation signals to an external device. The invention also discloses a flowmeter signal simulator. The flowmeter signal simulator comprises the CPU chip, the communication chip, the power supply transformation chip, a wire connection terminal, a crystal oscillator and three dial switches. The simulator can be installed and used on a device which is to be subjected to simulation detection. The invention further comprises a fuel dispenser simulation detection method. The flowmeter signal simulator and the flowmeter signal simulation
