Claim:
1. A flow rate measuring device capable of correcting a gradient, comprising: a sensor unit provided on a bottom surface of an inner portion of a fuel tank, and sensed information for measuring a current flow rate value remaining in the fuel tank and transferring the sensed information; a calculating unit calculating the current flow rate value remaining in the fuel tank using the sensed information transferred from the sensor unit per preset time or depending on a request of the outside; and a displaying unit displaying the current flow rate value transferred from the calculating unit, wherein the sensor unit includes: an ultrasonic sensor attached onto the bottom surface of the inner portion of the fuel tank and sensing distance information indicating a distance value between the bottom surface of the inner portion of the fuel tank and an oil surface of oil remaining in the fuel tank; and a gradient sensor attached onto the bottom surface of the inner portion of the fuel tank and sensing gradient information indicating a gradient value of the fuel tank.
