Fuel dispenser with seismic vibration perception function.
A fuel dispenser with a seismic vibration perception function includes a pump motor, a fuel feeding pump, a flow volume measuring member, a nozzle switch and a fueling control member. The fuel-feeding pump is driven by the pump motor. The flow volume measuring member measures the amount of fed fuel and outputs a flow volume pulse signal. The nozzle switch transmits a nozzle-unhooked signal and a nozzle-hooked signal. The fueling control member causes the pump motor to be "on" and "off" by receiving the nozzle-unhooked and the nozzle-hooked signal respectively and counting the flow volume of fuel by receiving the flow volume pulse signal. The fueling control member contains a seismic vibration perception member for perceiving vibration and transmitting a seismic vibration perception signal for suspending electric supply to the pump motor.
