The invention discloses a method for automatically calculating oil mass through pressure sensor data, which comprises the following steps of: acquiring the pressure sensor data once every 10 seconds, converting the pressure sensor data into height, and putting the height into a 13-data queue; the latest collected height data is preprocessed, and the upper sharp data and the lower sharp data are smoothed; the method comprises the following steps: step 1, comparing trend judgment of previous and later data, if the current data has a trend which does not meet the previous and later data, actively carrying out re-assignment on the current data by using an average value of the previous and later data, and carrying out smooth filtering on abnormal and prominent data, step 2, acquiring a pressure value by a pressure sensor, and detecting the acquired pressure value based on 20 times of normal flow velocity; according to the method, the refueling event of each time of the machine can be identified, the customer can b
