This design is an advanced petroleum dispenser that incorporates a fire suppression method activated by a heat sensor mounted upon the fuel dispenser. The fire suppression tube does go through the entire dispenser to then vent a dry chemical correctly rated for petroleum products such as oil and diesel fuel. The fuel dispenser"head" will have upon the top of the unit a meter displaying the amount of fuel dispensed and an automatic kick off method via sonic sensor then by sound pitch then causing the fuel to halt dispensing. Audio pick up microphone sound intake tube then at the fuel tube tip ( the sound tube then connects to the sensor within the dispenser ). The sonic sensor also contains fault indication safety system circuit to then prevent the fuel from dispensing if the sonic sensor is inoperable. The sound tube is then metal and mated to the fuel dispenser tube.
