1).LCD and mechnical wheel display
2). ISO9001:2008, A grade.

Functional features:

   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.Low power consumption design, combined automatical power failure technology, static power consumption of gas meter is less than 10μA.

   3.Mechnical print wheel displays accumulated gas content, and LCD displays residual gas content, Reliable measurement and high precision.

   4.Prevent the attack from external electricity and magnetism. Gas meter will automatically stop valve when there is strong electricity and  magnetism attack from outside.

   5.It has sound notification and liquid crystal display function during battery is shortage, gas content is deficiency and illegal operation.

   6.Microcomputer, micro memory technology. High-integration and reliablity.

   7.It has data storage function, and even when changed battery.

   8.It is easy to debug due to the configuration of left and right meters.
