The new improvement of fuel dispenser’s configuration fuel dispenser and performance, electronic fuel dispenser d fuel dispenser evelopment in particular, promoting the progression of operation control, display technology of homemade fuel dispenser. In the early of 1990s, the annual productivity of fuel dispenser in china was 40,000 sets. The total number of filling station was more than 10,000 with 70,000 or 80,000 sets of fuel dispenser. Therefore, China has rapidly finished the shift from mechanical fuel dispenser to electrical one. In 2002, and has become the real largest fuel dispense country with more than 80,000 commercial filling station mounted 300,000 fuel dispensers. The technological level of fuel dispenser quickly access to that of international market. The introduction of national technology supervision, input of design and manufacture technology about fuel dispenser from developed countries such as American, Japan, Britain, France, Italy, etc, have vigorously promoted the china’s technological progression of fuel dispenser.
