Determining Atmospheric Pressure from UWI

In the previous blog post we went through a couple examples outlining the importance of having the correct atmospheric pressure entered into an Electronic Flow Meter’s configuration. So how do we go about determining the correct atmospheric pressure at a given location? Some EFMs have built in capability to determine atmospheric pressure based on elevation. […]

Effects of Incorrect Atmospheric Pressure Correction

The AGA 3 and 8 Calculations reference atmospheric pressure. So does Directive 017 and API 21.1. But how exactly does it effect to gas measurement? If you refer back to your high school chemistry you will recall that base pressure is defined as 101.325 kPa. This is also the atmospheric pressure at sea level. When […]
