1. Detailed explanation of how to adjust the fuel dispenser display counter

Adjusting the fuel dispenser display counter without authorization is illegal and may involve measurement fraud. It must be operated by professionals or regulatory authorities.

1. Adjustment steps for old-fashioned mechanical fuel dispensers 1 Find the adjustment device: Disassemble the body shell and crack the sock inside the flowmeter to position the gear set or adjust the screw. two Adjusting gear meshing: Control the flow rate by increasing or decreasing the number of teeth in the gear meshing. If the number of teeth increases, the flow rate will increase; otherwise, it will decrease. three Adjust piston stroke: Turn the adjusting screw to change the piston/slide stroke. Extend the stroke to increase the single measurement volume, and shorten it to reduce the volume.

2. Adjustment steps for contemporary electronic fuel dispensers 1 Enter the backend system: Unlock the device with a password or key and enter the calibration or parameter settings menu. two Correction of flow coefficient: locate the measurement coefficient option in the menu and directly enter the numerical value or fine tune the coefficient. If the coefficient is increased, the displayed value will increase; if it is decreased, the value will decrease. three Calibration verification: After saving the parameters, it is necessary to test with a standard meter to confirm that the displayed value and actual flow error comply with the national standard.

3. Legal risk warning for operation. The adjustment device of a fuel dispenser usually has a tamper proof lead seal and a four travel trigger. Disassembling it without authorization will damage the sea

. The Metrology Law stipulates that the adjustment of measuring instruments must be verified by statutory institutions, and illegal adjustment may face administrative penalties and even criminal responsibility. When the equipment malfunctions, it should be immediately stopped from use and the market supervision department should be contacted for inspection and maintenance.

2. Adjustment method for fuel dispenser gauge

1. Ensure that the fuel dispenser operates normally: check the working status of each component of the fuel dispenser to ensure that there are no faults or air leaks.

2、 Ensure the normal operation of the fuel dispenser: Check the working status of each component of the fuel dispenser to ensure that there are no faults or air leaks.

3、 Set benchmark measurement value: According to national standards, set the benchmark measurement value in a rigid manner. The benchmark measurement value is pre calibrated and can accurately display the quantity measured by the fuel dispenser.

4、 Adjust the liquid level control system: Firstly, adjust the liquid level control system to accurately control the oil level in the tank. By adjusting the liquid level control system, it is possible to ensure accurate measurement of oil volume during the refueling process of the fuel dispenser.

5、 Adjusting the flowmeter: Based on the benchmark measurement value, use tools such as adjusting screwdrivers and throttling devices to gradually adjust the sensitivity and accuracy of the flowmeter. By continuously adding fuel, checking the reading of the gauge, and comparing it with a standard gauge, gradually adjust the flow meter to accurately measure the amount of fuel added. 『SILVER Official Website SERVICE』
