Answer: When the actual pressure of the fluid being measured is lower than the external pressure, the pressure value read by the gauge is referred to as vacuum level. http://bbs.hcbbs.com/static/image/hrline/4.gif Petrochemical Zone—New Ideas for Energy Saving: The “Creative Thinking” Campaign (Sponsors sought; highest returns ever offered) http://bbs.hcbbs.com/thread-1666758-1-1.html Sponsors are being sought for this campaign; those interested can contact the event organizer.

When the actual pressure of the fluid under test is lower than the external pressure, the pressure value measured by the gauge is referred to as vacuum level. At this point, absolute pressure = atmospheric pressure - vacuum level
The degree of gas thinness in a vacuum state
Refers to the degree of thinness of a gas in a vacuum state
Vacuum degree refers to the degree of thinness of the gas in a vacuum state. If the pressure inside the device being measured is lower than atmospheric pressure, a vacuum gauge is required for pressure measurement. The value read from the vacuum gauge is called the degree of vacuum.
The degree of thinness of a gas in a vacuum is usually expressed by the vacuum level. If the pressure inside the device being measured is lower than atmospheric pressure, a vacuum gauge is required for pressure measurement. The value read from the vacuum gauge is called the degree of vacuum. The vacuum degree value represents the extent to which the actual pressure in a system is lower than atmospheric pressure; that is, Vacuum degree = (Atmospheric pressure – Absolute pressure)
It refers to the pressure level that is lower than normal atmospheric pressure; this value is called vacuum degree
When the actual pressure of the fluid under test is lower than the external pressure, the pressure value measured by the gauge is referred to as vacuum level.
Vacuum degree refers to the degree of thinness of the gas in a vacuum state. If the pressure inside the device being measured is lower than atmospheric pressure, a vacuum gauge is required for pressure measurement. The value read from the vacuum gauge is called the degree of vacuum. The vacuum degree value represents the extent to which the actual pressure in a system is lower than atmospheric pressure; that is, Vacuum degree = Atmospheric pressure – Absolute pressure, and Absolute pressure = Atmospheric pressure + Gauge pressure (–Vacuum degree)
Vacuum degree = Atmospheric pressure - Absolute pressure
