LNG dispenser

LNG liquid dosing machine technology leading advantages

High measurement accuracy, stable system, simple maintenance and long service life

Selection of measurement method: According to national requirements, select a high-reliability mass flow meter

Carry out measurement to avoid volume measurement being troubled by the accuracy of temperature, pressure, density and other factors.

1. Low flow compensation.

2. Stiffness correction

3. Zero point adjustment function

4. When adding liquid in a non-quantitative manner, the pump is automatically stopped by controlling the flow rate or pressure parameters, and a special calculation program is used to ensure that it can be filled with gas but not overfilled;

5. It has an internal circulation process. When the refueling time between two vehicles is short, there is no need to perform a large cycle, saving time;

6. The entire set of equipment needs to have stable working performance to ensure that the LNG flowing through the equipment can reduce vaporization as much as possible under ultra-low temperature conditions and ensure the singleness of its liquid state;

7. The LNG dispenser is equipped with a national patented LNG pull-off valve. When the pull-off valve is pulled off, the liquid filling gun is cut off to ensure that no residual LNG liquid will flow out.

8. Improve the highly reliable lightning protection design to effectively avoid damage to equipment caused by induction lightning, direct lightning strikes, etc.;
