The basic working principle of fuel dispenser can be illustrated by the following chart 1-19, the line with arrow presenting flow direction of oil, line denoting the transmission direction of mechanical or electric sign. Diagram 1- 19: Working process of fuel dispenser Fuel is sucked from underground tank, enter measurement transducer via vapor separator, and flow out nozzle through solenoid v fuel dispenser alve. The position movement value of axis generated by transducer is converted into relevant electric pulse sign by sensor, the indicator of electric counter display accumulative volume refueled. If in mechanical fuel dispenser, the volume refueled can be presented by the indicator device of mechanical counter by measuring the position movement fuel dispenser of output axis of converter. The pump of submersible fuel dispenser is installed in oil in tank, which can delivery fuel to several measurement transducers, and flow out nozzle. Its counter device is similar to pump built-in fuel dispenser. The current fuel d

r, look back five years, not 40. In the second half of 2000 the yield curve inverted, and then, as now, the vast majority of commentators dismissed it, arguing that the old portent had nothing to say about the new economy. Three months into 2001, the economy slipped into recession. Although monetary policy may not be that tight as yet, the economy s strength may rely, more than most realise, on interest fuel dispenser rates remaining low. To a disturbing degree, America s economy is still debt-led. Can this borrowing continue to drive growth now that interest rates are no longer “accommodative�and house prices are starting to cool? The answer is not easy to find in the bond market. But it will decide whether America s economy is as flat in the year ahead as the yield curve is today. * “The Yield Curve as a Leading Indicator Frequently Asked Questions� October 2005.
