pressure measurement
Pressure transmitters can measure pressure, gauge pressure, or differential pressure.
pressure
Pressure refers to a perfect vacuum, considered to be 0 psi! We express the vacuum pressure as 0 psi (a).
The atmospheric pressure is typically around 14.7 psi (a).
Gauge pressure
The common pressure measurement is gauge pressure, which is the total pressure minus atmospheric pressure.
The atmospheric pressure is 0 psi (g).
As discussed in our previous article, the versatility of differential pressure transmitters allows us to flexibly measure liquid level, flow rate, and pressure.
