Abstract
A fuel quality sensor can include a pump with a suction side and a pressure side for pumping fuel along a fuel flow path between an underground reservoir and a nozzle of a fuel dispensing unit; a first transmitter disposed at the suction side of the pump on a first side of a bypass plenum in fluid communication with the fuel flow path, the first transmitter configured to transmit a first light signal at a first predetermined frequency in the bypass plenum; a receiver disposed at the suction side of the pump on a second side of the bypass plenum and configured to receive the first light signal; and a control unit electrically connected to the first transmitter and the receiver and configured to determine at least one parameter of the fuel present in the fuel flow path based on the received first light signal at the first predetermined frequency.
