A modern fuel dispenser is divided into two main parts – an electronic "head" containing an embedded computer to control the action of the pump, drive the pump's displays, and communicate to an indoor sales system; and a mechanical section which (in a self-contained unit) has an electric motor, pumping unit, meters. Fuel dispensers are also known as bowsers, petrol pumps, or gas pumps.
It works by sending small pulses of gasoline through the line. If there is still air in the tank, the pulses are dissipated in the tank, if the tank is full; the pulse is returned through the hose and detected. When the return pulse is detected it stops the pump. A device connected to the dispenser meter and that converts the mechanical movement of the meter mechanism to electrical pulses that control the dispenser's electronic display of the volume and cost of the fuel dispensed.
When we look at the history of the invention of fuel, Petrol is the first to make an entry. The Petrol engines was thought to be commercial ready and more stable than diesel engines. The petrol vehicles struck the market and so did the fuel (Petrol) dispensers (Station).
A fuel dispenser is a machine to pumps gasoline, diesel, or other liquid fuels. Also known as fuel pumps in East Europe. Also, there are different names in different countries too. For example; petrol bowser in Australia, petrol pump in Commonwealth countries, or gas pump in North America.
The term unleaded is short for unleaded petrol and it refers to the fact that the fuel comes without lead compounds. All modern day petrol cars in the western world run on unleaded fuel.
How do you dispense fuel without a meter reading? Go into the store and ask which tank has the grade of fuel you require. Then go over to that tank and take the cap off, drop your bottom hose in there, put the top hose into your fuel tank and pump away. Pull the trigger slowing to between ½ and ¾ open on the nozzle to dispense the fuel. If the nozzle is activated too quickly, a leak detector will automatically slow pumping to a trickle. If this happens, release the trigger on the nozzle and wait 10 seconds. Pull trigger back on and pumping should be normal.
Filling Station: (service station or gas station) - Any building or premises used principally for the dispensing, sale or offering for sale at retail of automobile fuels or oils. Fuelling Station (Retail) – Also known as a filling station, gas station, service station or petrol station.
The two most widely used fuel feed pumps are diaphragm and plunger-type mechanical pumps. Diaphragm pumps are a type of positive displacement pump. Diaphragm pumps contain a pump chamber whose volume is increased or decreased by the flexing of a flexible diaphragm, similar to the action of a piston pump.
Premium gasoline is generally considered any type of gasoline with an octane level of 91 or greater, with 91 octanes and 93 octanes being the most common versions of premium gasoline available at gas stations in the United States (93 octane gasoline may be called “ultra” or “super-premium” in some cases).
Petrol pumps measure fuel by using a petrol flow meter which is a PD flowmeter type. The operator sets a currency/litre based setpoint which the PD flowmeter calculates instantaneously by segmenting the volume into smaller volumes and eventually measuring the dispensed fuel litres.
