From a nursing perspective...
The gauge of the needle tells us the size of the lumen (inside) of the tube. Size 18 is big whilst size 30 is small. If we want a substance that we're injecting to have low pressure (ie if cleaning a wound with saline and not wanting it to hurt or disturb the healing and using a syringe to apply it) then we use a large size (ie 16).
Hope this helps
Gauge pressure is the pressure recorded on the gage that records above the atmospheric pressure. Normal atomospheric pressure is 14.7psi. So if a gage read 10 psi of gage pressure, then the true pressure would be 24.7 psi.Hope this is right.

What is strut pressure?
pressure of a strut
How does air pressure affect air movement?
Air pressure affects air movement because air moves from high pressure to low pressure. The air pressure pushes or will press the air around.
What is ansi b40.1?
ANSI B40.1 has been replaced by ANSI/ASME B40.100-2005Pressure Gauges and Gauge AttachmentsThis Standard (B40.1) is confined to analog, dial-type gauges, which, utilizing elastic elements, mechanically sense pressure and indicate it by means of a pointer moving over a graduated scale. This Standard does not include gauges of special configuration designed for specific applications, edge reading, deadweight or piston gages, or any other gauges not using an elastic element to sense pressure
What is the source of error in a bourdon gauge?
· Friction· Wear· And backlash in gears.
What is the difference between normal pressure gauge and differential pressure gauge?
A pressure gauge indicates actual pressure and a differential pressure gauge indicates the difference in pressure.
Why pressure gauge is called a gauge not a meter?
Because Pressure gauge measures the the differenceof pressure so it is called pressure gauge not meter.
Definition of a compound gauge?
A compound gauge is a pressure gauge that displays both negative and positive gauge pressure measurements. Gauge pressure is a measurement of pressure relative to ambient pressure. For example, if ambient pressure was 14.7 PSI and you were to measure absolute vaccum using a compound gauge, the gauge would indicate -14.7 PSI.
Can bourdon's tube pressure gauge be used to measure negative pressure?
Bourdon's tube pressure gauge cannot be used to measure negative pressure. This is because absolute pressure must be measured and the Bourdon gauge only indicates the gauge pressure.
What gauge measures both vacuum and pressure?
Gauge pressure usually refers to the pressure difference between ambient, atmospheric pressure and the pressure in a vessel or line. A gauge pressure of zero would mean that the vessel or line was at atmospheric pressure. Normally the pressures of interest are ABOVE atmospheric so the gauge pressure is positive. Vacuum gauge pressure measures how far BELOW atmospheric pressure a vessel or line is. As such vacuum gauge pressure may be measured as a negative number - or for convenience it may be reported as a positive number with the caveat that it is "vacuum gauge pressure", meaning that the reported pressure is how far atmospheric pressure is above the pressure in the vessel or line.
What is micro manometer pressure?
A manometer is a pressure gauge. A micro manometer is either a really small pressure gauge, or a pressure gauge used to measure really small pressure difference.
What is the principle of pressure gauge?
pressure gauge works on hooks law principle ,when we applying pressure in end connection of the pressure gauge ,the same pressure operating at end of the bourdon tube.
Can you use an oil pressure gauge in the place of air pressure gauge?
No.No.No.No.
Why diaphragm of a pressure gauge is corrugated?
These are corrugated to increase the sensitivity of the pressure gauge.
What is micro manometer?
A manometer is a pressure gauge. A micro manometer is either a really small pressure gauge, or a pressure gauge used to measure really small pressure difference.
