Precision in the measurement of fuel is of great importance to both fuel station operators and users. The gasoline dispenser pumps should be in a way that they can dispense the right quantities of fuel and in a manner that is fair to the customers, complies with the regulations and makes customers trust them. Calibration of the dispenser fuel pump is a key role of this accuracy in the long run. The pump of a gasoline dispenser has mechanical or electronic flow meters to measure the flow. These meters determine the amount of fuel that passes through the system and show it in real time. To display the correct amount of fuel, the dispenser fuel pump is correctly calibrated to deliver the correct amount of fuel into the vehicle. Any minor mistakes can cost the fuel station owners financial losses, penalties and even reputation.
