Is there any connection between the oxygen valve and the oxygen meter? How to adjust the data between them to save gasoline? Thank you for your suggestions! ~~

The oxygen meter is used to indicate the pressure before and after the oxygen valve respectively.

For mobile oxygen storage equipment (steel cylinder), the biggest function of valve pressure is to prompt whether oxygen is used up. The pressure behind the valve must usually meet the requirements of use. Oxygen consumption rate refers to the flow rate under the pressure that meets the use requirements. Therefore, adjusting the pressure has little effect on saving gas. The key to improve oxygen utilization rate is to find ways to reduce gas consumption.
