In todays competitive environment, businesses are becoming increasingly dependent on technology, making it imperative for petrol pump owners to be in tune with. Fuel dispenser WikipediaGas pump redirects here. For the similarly named film, see Gas Pump Girls. A fuel dispenser is a machine at a filling station that is used to pumpgasoline, petrol, diesel, CNG, CGH2, HCNG, LPG, LH2, ethanol fuel, biofuels like biodiesel, kerosene, or other types of fuel into vehicles. Fuel dispensers are also known as bowsers in Australia,1petrol pumps in Commonwealth countries, or gas pumps in North America. HistoryeditThe first gasoline pump was invented and sold by Sylvanus Bowser in Fort Wayne, Indiana on September 5, 1. This pump was not used for automobiles, as they were not yet being sold. It was instead used for some kerosene lamps and stoves. He later improved upon the pump by adding safety measures, and also by adding a hose to directly dispense fuel into automobiles. For a while, the term bowser was used to refer to a vertical gasoline pump. Although the term is not used anymore in the United States, except as a term for trucks that carry and dispense fuel to large aircraft at airports, it still is used sometimes in Australia and New Zealand. Petrol Pump Management Software' title='Petrol Pump Management Software' />The first fuel dispenser was patented by Norwegian John J. Tokheim in 1. 90. Petrol Pump Management Software Free DownloadFuel retail industry giant Tokheim OPW, was named after him. Many early gasoline pumps had a calibrated glass cylinder on top. The desired quantity of fuel was pumped up into the cylinder as indicated by the calibration. Then the pumping was stopped and the gasoline was let out into the customers tank by gravity. When metering pumps came into use, a small glass globe with a turbine inside replaced the measuring cylinder, but assured the customer that gasoline really was flowing into the tank. A modern fuel dispenser is logically divided into two main parts  an electronic head containing an embedded computer to control the action of the pump, drive the pumps displays, and communicate to an indoor sales system and secondly, the mechanical section which in a self contained unit has an electric motor, pumping unit, meters, pulsers and valves to physically pump and control the fuel flow. In some cases the actual pump may be sealed and immersed inside the fuel tanks on a site, in which case it is known as a submersible pump. Petrol Pump Management Software Source Code' title='Petrol Pump Management Software Source Code' />In general, submersible solutions in Europe are installed in hotter countries, where suction pumps may have problems overcoming cavitation with warm fuels or when the distance from tank to pump is longer than a suction pump can manage. In modern pumps, the major variations are in the number of hoses or grades they can dispense, the physical shape, and the addition of extra devices such as pay at the pump devices and attendant tag readers. Light passenger vehicle pump flow rate ranges up to about 5. US gallons per minute3 the United States limits this to 1. US gallons 3. 8 litres per minute4 pumps serving trucks and other large vehicles have a higher flow rate, up to 1. US gallons per minute in the UK,3 and airline refueling can reach 1,0. Petrol Pump Management Software' title='Petrol Pump Management Software' />US gallons 3,8. Higher flow rates may overload the vapor recovery system in vehicles equipped with enhanced evaporative emissions controls6 required since 1. US, causing excess vapor emissions, and may present a safety hazard. Historically, fuel dispensers had a very wide range of designs to solve the mechanical problems of mechanical pumping, reliable measurement, safety, and aesthetics. This has led to some popularity in collecting antique dispensers, especially in the USA. Fuel nozzleseditNozzles are attached to the pump via flexible hoses, allowing them to be placed into the vehicles filling inlet. The hoses are robust to survive heavy wear and tear, including exposure to weather and being driven over, and are often attached using heavy spring or coil arrangements to provide additional strength. A breakaway valve is also fitted to the hose to allow the nozzle and hose to break off and fuel flow to be stopped in the case a vehicle drives off with the nozzle still in the filler, although this is largely prevented todaycitation needed by the point of sale systems not allowing payment for fuel until the nozzle is returned to its petrol pump holder. The nozzles are usually color coded to indicate which grade of fuel they dispense, however the color coding differs between countries or even retailers. For example, a black hose and handle in the UK indicates that the fuel dispensed is diesel, and a green dispenser indicates unleaded fuel the reverse is common in the US. Some different types of fuel have specially sized of nozzles to prevent accidentally filling a tank with an incompatible fuel. The nozzle on diesel pumps is supposed to be larger so that it cannot fit into the filler pipe on a vehicle tank designed for gasoline. However, the larger diameter diesel nozzles are not an actual requirement, and many diesel pumps at auto islands have been fitted with standard gasoline nozzles. Also, the nozzle for leaded gasoline is wider than for unleaded, and the fill pipe on vehicles designed for unleaded only was made narrower to prevent mis fueling. Some diesel fuel tanks are designed to prevent wrong type of nozzle to be used. BlendingeditIn some countries, pumps are able to mix two fuel products together before dispensing this is referred to as blending or mixing. Typical usages are in a mix pump to add oil to petrol for two strokemotorcycles, to produce an intermediate octane rating from separate high and low octane fuels, or to blend hydrogen and compressed natural gas HCNG. The benefit of blending for retailers is that it allows them to offer 3 grades of fuel while only having to maintain inventory of two grades. This frees up both working capital and tank capacity and improves fuel turnover. Microsoft Office 2007 Pro Torrent French. Flow measurementeditOne of the most important functions for the pump is to accurately measure the amount of fuel pumped. Flow measurement is almost always done by a 4 stroke piston meter connected to an electronic encoder. In older gas pumps, the meter is physically coupled to reeled numerical displays moving wheels or cylinders with numbers on the side, while newer pumps turn the meters movement into electrical pulses using a rotary encoder. In the U. S. flow speed is limited to 1. This flow rate is based on the diameter of the vehicles fuel filling pipe, which limits flow to these amounts. The metrology of gasolineeditGasoline is difficult to sell in a fair and consistent manner by volumetric units. It expands and contracts significantly as its temperature changes. A comparison of the coefficient of thermal expansion for gasoline and liquid water at 2. C indicates that the volume of gasoline changes at about 4. In the United States, the National Institute of Standards and Technology NIST specifies the accuracy of the measurements in Handbook 4. The standard accuracy is 0. US gallon 3. 7. L purchase may actually deliver 9. US gal 3. 7. 7 L to 1. US gal 3. 8. 0 L. The reference temperature for gasoline volume measurement is 6. F or 1. 5C. 9 Ten gallons of gasoline at that temperature expands to about 1. US gal 3. 8. 4 L at 8. F 2. 9 C and contracts to about 9. US gal 3. 7. 2 L at 3. F 1 C. Each of the three volumes represents the same theoretical amount of energy. In one sense, ten gallons of gasoline purchased at 3. F is about 3. 2 more potential energy than ten gallons purchased at 8. F. Most gasoline is stored in tanks underneath the filling station. Modern tanks are non metallic and sealed to stop leaks.
