1)dual display IC card gas meter
2)high accuracy and low power consumption
3)guaranteed quality, best post-service
Scope of applications:
Apply to flow measurement of inflammable gas, such as natural gas, liquefied oil gas, coal gas and etc. Consumers can use gas by card, and one card, one gas meter. Air volumn in gas meter will be input, and valve of gas meter can automatically open and start to supply gas.When it use up, valve will close automatically and gas source can stop surely. Consumers need to purchase gas again and insert the card into meter for next use.
The characteristics:
1. Integral design, all circuits and electronic control valves are built in the meter, and outside the gas chamber. Be reliable at work, and little pressure loss.
2. Prevent the attack from external electricity and magnetism. Gas meter will automatically stop valve when there is strong electricity and magnetism attack from outside.
3.It has sound notification and liquid crystal display function during battery is shortage, gas content is deficiency and illegal operation.
4.Microcomputer, micro memory technology. High-integration and reliablity.
5.It has data storage function, and even when changed battery.
6. It is easy debug due to the configuration of left and right meters.
