Depending on the application, high-pressure flow meters can be used to measure the flow of high-pressure gases and liquids.
High pressure liquids are generally gaseous under normal pressure. It will change into a liquid when it reaches a certain pressure. If the air pressure becomes instantaneously low, the liquid will quickly vaporize, expand in volume, cause an explosion, and absorb a large amount of heat. If it is said that the hazard in the explosion should be the point where the high-pressure liquid is harmful.
Because the gas is converted into a liquid under high pressure, the volume will be greatly reduced. So, in contrast, the destructive force will be greater when the high-pressure liquid explodes.
