TEMPERATURE AND VOLUME MEASURING SYSTEM OF FUEL TANK AT VEHICLE BY USING GAS PUMP

摘要

The present invention relates to a real time temperature and fuel measuring system for a fuel tank of a vehicle which measures a corrected fuel rate in accordance with a temperature of a state in which two fuels are mixed. According to the present invention, the real time temperature and fuel measuring system for a fuel tank of a vehicle comprises: a refueling pipe connecting the fuel tank of the vehicle to an oil hole; and a protruding circular diagonal unit installed in the refueling pipe and facilitating the inflow of fuel. The real time temperature and fuel measuring system for the fuel tank of the vehicle comprises: a sample flow rate unit; a vehicle instrument unit receiving a temperature sensor signal from a temperature sensor transmission unit and changing a residual fuel rate information and residual fuel temperature information into a digital value and receiving the same from a fuel tank measurement device terminal, correcting refueling rate information newly refueled when the fuel is refueled from the oil hole based on the temperature information measured in real time of a temperature sensor, and calculating a corrected total fuel amount by adding up the residual fuel rate corrected based on the temperature and stored in the fuel tank and the corrected refueling rate, and providing the total fuel amount and the fuel temperature information by a display unit; a refueling pump terminal registering a vehicle terminal number and transmitting the refueling rate information refueled in the vehicle to the registered vehicle instrument unit when paying by a banking facility server; and a fuel tank measuring device terminal measuring the residual fuel amount and the residual fuel temperature stored in the fuel tank of the vehicle, changing the same into the digital signal, and transmitting the changed digital signal to the vehicle instrument unit. The sample flow rate unit comprises: an inlet pipe connected to a lower part of a body unit; the body unit connected to the inlet pipe; an outflow pipe which is the lower part of the body unit and connected to an opposite side to the inlet pipe, wherein the outflow pipe is formed in 1/8-1/10 of an inner diameter of the inlet pipe and connected to the refueling pipe; a temperature sensor measuring the temperature when the fuel is stabilized by being installed in the upper part of the inside of the body unit; and a temperature sensor transmission unit changing the sensor signal of the temperature sensor into the digital signal, and transmitting the digital signal.
