The marine fuel dispensers circuit includes power, control, pulse, display and lightning protection, anti-static circuit, which mine, anti-static circuit is the focus of attention.
Circuit hidden trouble is not easy to detect, because the electricity is invisible, in addition to the occurrence of power short circuit, circuit or voltage instability, etc., will cause the fuel dispensing meters dysfunction and was found, the electrostatic ground contact bad or virtual connection, usually does not fail , And by the human senses can not be judged, so easy to be ignored. Therefore, we must use a multimeter, according to the provisions of the time interval to detect, the general site refueling gun to detect once a month is appropriate, the seaside and more serious corrosion areas, should improve the detection frequency to once every half months.
