penser homemade has two functions of manual and automatic zero clearing. This kind of motor–operated fuel dispenser processed the international technology in 1950s.

Automotive industry and petrol industry as well as transportation industry have attained the unprecedented development. The number of filling station has increased to 6,000 from 600, fuel dispenser to 20,000 sets. The new improvement of fuel dispenser’s configuration and performance, electronic fuel dispenser development 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 fuel dispenser with more than 80,000 commercial filling station mounted 300,000 fuel dispensers. The technological level of fuel dispenser quickly access to fuel dispenser 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.
