Fuel dispenser

Fuel dispenser

A pump, manufactured by Dresser Wayne, in Greece A Fuel dispenser is a machine at a filling station that is used to pump gasoline, 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)

HistoryThe first gasoline pump was invented and sold by Sylvanus F. Bowser in Fort Wayne, Indiana on September 5, 1885.[2] This pump was not used for automobiles, as they had not been invented yet. 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, it still is used sometimes in Australia and New Zealand.

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.

Hydrogen station pumpA 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 pump s 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 regions, regular required inspections are conducted to insure the accuracy of Fuel dispenser. For example, in the US state of Florida, the Florida Department of Agriculture and Consumer Services conducts regular tests of calibration and fuel quality at individual dispensers. The department also conducts random undercover inspections using specially designed vehicles that can check the accuracy of the dispensers. The department issues correction required notices to stations with pumps found to be inaccurate.[5] Most other US states conduct similar inspections. In Canada, inspections are regularly conducted by the federal government department Measurement Canada. Inspection dates and test results are required, by law, to be displayed on a sticker on fuel dispensers for consumers to see. Under a recently proposed legislation by the House of Commons (C-14: Fairness at the Pumps Act), fines for a vendor with a modified fuel dispenser or poorly maintained dispenser would be up to $50,000. However, virtually all pumps that fail inspection in Canada do so for general calibration errors caused by use over time. Intentional modification for the purpose of deceiving consumers is extremely rare. http://www.datianmachine.com/
