A fuel dispenser or fuel dispensing equipment is a tool that is used for pumping fuels like Diesel, CNG, Gasoline, Kerosene, High octane and all the other variants into vehicles. A fuel dispenser unit primarily contains two main parts. One is the controlling head, which has an embedded computer and the other is the mechanical part.
These two are the primary components of a fuel dispenser or tank gauging system. The CPU installed within the mechanical system controls the pumping flow rate, displays logs, and connects to a sales system; while the mechanical system itself has electrical motors, gauges, meters and valves.
The whole system contains a submersible pump that immerses in the fuel tank for the transfer process to progress. However, in the case of distant fuel tanks, a suction pump may be involved to draw fuel from the storage to the dispensing unit.
A gasoline/diesel/hi-octane dispensing unit can have more than one hose, and the nozzles attached at the end of these hoses are inserted in the vehicle’s fuel tank for the fuelling process. The material chosen to manufacture hoses can be as such, that it can withstand harsh weather conditions, and wear and tear over a long period. The nozzles may be color-coded to distinguish which type and grade of fuel are they going to dispense.
Color coding may vary from country to country and company to company. Nozzle sizes differ to avoid accidental pumping of incompatible fuel within a tank. Generally, a diesel-pumping nozzle is larger and it cannot fit in a small-sized gasoline fuel inlet of a gasoline-vehicle.
Modern technology allows gasoline and diesel distributors, to have display features and human-machine interfaces, which enable consumers to interact with them and be as user friendly as possible. Magnetic card readers enable customers to use their credit/debit cards for eased payments. While using these features customers can also get to check their transactions by entering their identification through numeric keypads.
A modern-day fuel dispensing equipment can even blend or mix two fuels in the right or predefined proportion before dispensing (relatively for particular predefined vehicles). An electronically controlled flow meter controls the accurate flow of the fuel amount that is to be pumped-in, in an automotive.
Modern tank gauging system alongside fuel dispensers are also equipped with a sensor-fit tube, which runs inside of the nozzle. The function of this tube is to cut off the flow of fuel as soon as the tank is full. Automatic Cut-Off is very necessary as it prevents the fuel from spilling out of the tank. Fuel dispensing equipment even contains the mechanism to prevent vapor loss of gasoline into the air by keeping the outflow speed in check (neither too fast nor too slow)!
These are some of the positive attributes related to a modern fuel dispenser which are constantly being upgraded with time for better reliability and usability. Safety is always kept first applied with the concept of efficiency while the transfer process takes place.
