1. How to adjust the flow meter of the diesel electronic refueling gun?
The adjustment of the flow meter of the diesel electronic refueling gun is mainly achieved through error coefficient calibration. The specific operation process is as follows:
1. Enter the calibration state. In standby mode or the current refueling amount display interface, long press the CALIBRATE button for 5 seconds to enter the error coefficient calibration mode of the system. At this point, the number will flash to display the currently set coefficient value, indicating that it has entered an adjustable state.
2. Modify coefficient numerical shift: Press the PLAY button, and the flashing numbers will move from left to right to locate the number of digits that need to be modified.
. Numerical adjustment: Press the CALIBRATE button, and the value of the current flashing bit will cycle from 0 to 9. Adjust the values according to demand, for example, changing the coefficient from 1.0000 to 0.9700 (reducing fuel consumption by approximately 1 liter for every 0.0100 decrease, with larger values resulting in more fuel consumption and vice versa).3. After saving and adjusting the settings, wait for 5 seconds. The system will automatically exit the calibration mode and return to the refueling state. At this point, the new coefficients have been saved.
. Be sure to ensure that the adjusted values meet the actual needs of hail prediction and avoid measurement deviation caused by coefficient errors.4. Key precautions Operation specifications: Strictly follow the operation manual provided by the manufacturer, and prohibit arbitrary changes to the adjustment method, otherwise it may affect the accuracy of measurem
Fifth, safety and compliance requirements. The adjustment of flow meters involves measurement accuracy, which is directly related to transaction fairness.
. Unauthorized adjustments or failure to pass quality inspection department certification may violate relevant regulations such as the Metrology Law, resulting in fines or equipment shutdown. It is recommended to have professional personnel operate and regularly submit for inspection and calibration. Through standardized operation and strict management, the measurement accuracy of diesel electronic fuel injector flow meters can be ensured, safeguarding user rights and ensuring compliant operation of enterprises.2.
