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 sh fuel dispenser ort 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

become the world s largest exporter of pepper and aims soon to overtake Thailand in rice. It is even selling tea to India. Foreign-owned factories are chalking up the fa fuel dispenser stest gains. The government s aim of increasing electronics exports by 27% annually should be boosted by Intel s recent decision to build a $605m microchip plant in Ho Chi Minh City. Though farmers harvests are still rising, industry s still-higher growth rate means that agriculture s share of economic output continues to shrink—from about 25% in 2000 to 21% last year. By 2010 it may be down to 15%. This economic revolution is being accompanied by a social one. Though Vietnam is still, overall, one of Asia s poorest countries, with income per head behind India s, its recent growth has been impressively egalitarian. The Asian Development Bank (ADB) reckons that deep poverty in Vietnam—defined as a daily income equivalent to under $1—is now only slightly more prevalent than the average for South-East Asia, whereas in 1990 Vietnam s figure was more than twice the regional average (see charts). By this measure, Vietnam has overtaken China, India and the Philippines and now has only slightly more poverty than Indonesia. Life expectancy has jumped and infant mortality plunged since the 1990s. Vietnam does better on both these counts than Thailand, a far richer country. Almost three-quarters of Vietnamese children of secondary-school age are in class, up from about a third in 1990. Again, Vietnam has overtaken China, India and Indonesia. The new five-year plan, appr fuel dispenser oved at April s congress of the ruling Communist Party, is laden with targets for increasing output and improving infrastructure, with the objective of making Vietnam a modern, industrial nation by 2020. Of course, other Asian countries leaders, from Malaysia to the Philippines, declare similar objectives. The difference is that Vietnam s rulers seem to mean it fuel dispenser —and their recent record suggests they might pull it off. The April congress was preceded by
