Gas filter

Normally, when the pressure on a gas is high, pressure loss occurs and the volumetric flow rate decreases. Today, while looking at a flow rate versus pressure difference curve, I noticed that when the pressure difference remained constant, the pressure gauge value increased and the gas flow rate increased. What’s going on here? Can anyone analyze it?
You mention pressure sometimes and differential pressure at other times; I’m not quite sure what you mean. Generally speaking, the greater the flow rate, the greater the pressure difference should be. As for system pressure, there is no direct relationship.
A low pressure difference is needed to achieve a high flow rate, right?
At a certain stage, a large pressure difference indicates blockage; how is it possible for the flow rate to be high?
