Fuel hand pump verification main standard with a standard metal gauge and thermometer, when the fuel hand pump after add oil to the standard metal basket, on the standard gauge of metal liquid level display glass tube by artificial leveling read the liquid level height, again through the input of the thermometer reads the balance of the oil temperature within standard gauge, then the formula for computing the volume and temperature correction formula calculated artificial 20 ℃ under oil standard volume, compared with fuel oil tankers in value calculation, it is concluded that the manual gas pump error value, finally, to determine whether the fuel tankers of error of qualified.The fuel hand pump method for the original static volumetric method tankers verification device, manual gas pump the device of three main drawback for:
1) by artificial reading level are highly dependent on the human eye to distinguish, the man-made is seen reading deviation, and surveyors working danger, difficulty reading;
2) each throw a diesel hand pump,  you read again the inside temperature and outlet temperature of the fuel tanker, safe, reliable, low efficiency;
3) calculation is difficult, because at the scene of the gas station operation, artificial after liquid level height and temperature value diesel hand pump is obtained to artificial calculation under 20 ℃ oil standard volume, computing workload is big, is not convenient, error-prone, and low working efficiency.
