s to quickly switch off power supply circuit in case that the associated circuit, connected power and used in explosive gas atmosphere, generate spark or become hot due to short circuit. Therefore, a reliable and valid safety barrier is very important to intrinsic safety fuel dispenser. The traditional safety barrier, adopting diode safety barrier, current fuse, voltage stabilizing diode and limited current resistance, is difficult to applicable to simple fuel dispenser due to expensive cost, large cubage and long time of melt. Owing to reliable performance, cost-efficient, quick response, electric safety barrier adopted VMOS component is widely mounted in most fuel dispenser at home and abroad.

At present, there are two kinds of popular pulse sensors in domestic market. One has double-way 30 pulses as per rotation of flow meter, the other double-way 50 pulses per rotation. Pulse sensor includes photoelectric sensor and Hall-effect Sensor. The circuit of popular photoelectric sensor is illustrated in Diagram 3-21 and 3-22. With the development of integrated circuit, a new kind of optical coupler is created, collecting the outside section of optical couple into inner so as to be simpler to use.

Therefore, the best solution is to install a touch switch on nozzle bracket. Mechanical key swit

to be decided. And it is not clear whether the new terms will reverse the precipitate fall in investment (see chart), and thus enable Bolivia to develop its reserves of natural gas, which are the second-biggest in South America. The nationalisation began with a bang in May, when Mr Morales led troops in occupying a gasfield operated by Petrobras, Brazil s state-owned energy company. But the government was slow to draw up new contracts. In September the president fired his energy minister after Brazil objected to his plan to expropriate refineries owned by Petrobras. He had earlier sacked the head of YPFB too. The new terms are less draconian for the companies than the May 1st nationalisation decree, but much harsher than their original contracts. fuel dispenser Petrobras, the biggest operator, with almost half of the gas reserves, will now pay royalties and taxes of 50% on its two biggest fields, down from 82% under the decree. After Petrobras defrays its costs (including amortisation) it will split the remaining revenue with YPFB under a variable formula. Broadly speaking, that is in line with a 2005 law approved under the government of Carlos Mesa. Mr Morales had judged this law so weak that he led the street protests that overthrew Mr Mesa. Other companies, including Spain s Repsol, Total of France and BG of Britain have signed similar new contracts. In some mature fields the tax take will total 80%. The new contracts give YPFB majority ownership of the industry. But the companies will be rather more than mere service providers. “We re not losing ownership, fuel dispenser �insists José Sérgio Gabrielli, Petrobras s fuel dispenser chief executive. His company will be “partners�with YPFB, which will have the right to “supervise�decisions on suppliers, he says. How that will work in practice is unclear. Talks are continuing over Petrobras s demand for compensation for its two Bolivian refineries, which are supposed to be turned over to YPFB. Also still under negotiation is an increase in the price Brazil p
