The present invention relates to an integral structure of ultrasonic level and alcohol concentration sensors of a fuel pump module. More specifically, unlike a conventional contact type sender, in order to measure an amount of fuel in a fuel tank by being mounted on a fuel pump embedded in the fuel tank of a vehicle, an apparatus is arranged to measure a level by converting a time required to send an ultrasonic signal and return by being reflected by a fuel surface into a distance using the ultra level sensor and the ultra concentration sensor. Accordingly, there is no problem with a poor contact point, electrode abrasion, emulsion response, etc., which are generated when a conventional contact type sender is used. In addition, the alcohol concentration sensor, which should separately be mounted, is able to also integrally be applied; thus reducing man-hours and manufacturing costs. In order to achieve these purposes, the integral structure of ultrasonic level and alcohol concentration sensors of the fuel pump module, comprises: a sensor housing fixated and mounted on an outer circumference; a terminal installed in a power supply part to receive power from a vehicle; a level sensor installed in a first sensor mounting part; a concentration sensor installed in a second sensor mounting part; and a control member connected to the level sensor and the concentration sensor. |
