Barometric Pressure Barometric pressure (P) in kPa from elevation (EL) in m above sea level was reported by Jensen, Burman and Allen, 1990 as P = ⎡ − EL
Measuring Total Pressure and Velocity Pressure
hvacrassets.netbarometric pressure of 29.92 inches Hg. To correct the velocity reading for other than standard air conditions, the actual air density must be known. It may be calculated if relative humidity, temperature and barometric pressure are known. Most manometer scales are calibrated in inches of water.

A vented gauge pressure transmitter for example allows the outside air pressure to be exposed to the negative side of the pressure sensing diaphragm, via a vented cable or a hole on the side of the device, so that it always measures the pressure referred to ambient barometric pressure.
