Not counting the oil tanker issue

1. Metal piston flowmeter stuck or broken diesel meterdrive pin on the shaft;
2. The sensor board is damaged or N3, N4 signal line reversed;
3. motherboard chipset motherboard is damaged or incorrect version number;
4. The signal lines are broken or virtual access situation.

Pause phenomenon tanker problems during refueling

When turned on, the baffle plate inside the switch did not fall into place, micro switch contact is not good; the grid voltage instability caused by this failure.
Bad wiring terminal board (screw not tightened the pressure line), gas station software in a halt during refueling tanker;
2V or 5V DC output voltage is low power board;
SCR board damage (phototriac conduction capacity decreased) also cause such a failure;
When the motherboard is faulty also make refueling pause phenomenon during diesel fuel flow meter.

Oil-leakage problem and solutions

1. The oil machine motor fuel management softwareinsulation breakage due to internal leakage;
2. Water or junction box wiring board insulation caused by decreased ability;
3. The external power input line Popi also in contact with the oil machine shell;
4. The machine internal circuits due to leakage caused by other reasons;
5. The machine does not have a reliablefuel management systemsand ground leakage protection circuit;
6. oil machine leakage, can easily cause fire and personal injury accidents, such as found in oil-leakage, must wind up immediately after stopping the leakage site and find out so completely solve the problem before being put into use again

Tanker display panel put the gun or firing when hops phenomenon and solutions

Oil-pipeline leaks and spills bottom valve closed lax, both machines will produce oil hops phenomenon when put the gun;
Using non-standard hose fuel management solutions machine oil hose freely lengthened or replaced, but also one of the reasons oil-generated power on the number of hops;
Sensor sensing shaft is too flexible, allowing the tanker to produce power-hops phenomenon, should repair the sensor shaft seal kit damping to reduce the flexibility of their rotation;
The oil valve spring tension is too weak, the shutdown of the oil diesel fuel meter back, driving off hops produce sensors reversal phenomenon;
Dual sensor assembly of photovoltaic panels in the wrong place, can cause the machine to produce oil at the time of switch hops.

Electronic metering filling gun

Using compressed air as the impetus for reciprocating piston manual fuel pump, lubricating oil were transported and annotated. Metering display panel and through the hose connection refueling gun, oil output, digital display flow, accurate, easy to operate, to achieve plant oil or other similar fluid filling for 180-220L vat of oil filling. Refueling system is currently the automotive repair shop, auto 4S stations, quick oil change service center, workshop production line choice for refueling fuel dispenser suppliers.

Fuel tanker works

Motor-driven gas fuel pump to the fuel tank in the filter pump through pipelines and oil separator oil and gas were separated, measurement converter flow through the fuel pump pressure, depending on oil, gun oil output to motor vehicles. Flow measurement converter output shaft via the angular displacement of the encoder is converted into a corresponding electrical pulse signal, by the electronic device displays the cumulative volume count indicates the amount of input fuel. Submersible pump dispenser pump fuel storage tanks located in, you can measure the converter output to multiple fuel flow, and then discharged through the oil gun. The tanker is now simple, remove the oil gun to start the petrol station management system, fill the tank can automatically close the gun, and the rest as a preset, adjust the unit price, starting, stopping, searching, all kinds of tips can be achieved by operating the keyboard
