Pressure Gauge 
                     Pressure 
Gauge
The pressure is measured 
through the analysis of the 
applied force by a fluid,
which can be gas or liquid, on a 
surface – the measurement is in 
units of force per unit of the 
surface area.
Pressure gauges are the 
instruments used to measure 
and display pressure in an
integral unit
Most gauges measure pressure 
relative to atmospheric 
pressure, form which is
referred to as “gauge pressure.”
For the most accurate reading, a 
vacuum gage is often used which 
provides
readings in the absolute scale
