Product Name: LGH High Pressure Loop Gas Flow Standard Device

The LGH high-pressure annular gas flow standard device uses clean air as the medium and circulates the air in a sealed annular pipeline through a high-pressure fan,

By using a compressor and a pressure regulating valve group, the air in the loop reaches the set pressure value, and by using a heat exchanger and cooling system, the temperature in the loop also reaches the set value,

Then, by comparing the volumetric flow rates flowing through the tested and standard meters during the same time period, the error and repeatability of the tested representative values can be determined.
