A novel approach using computational fluid dynamics techniques provides a way for determining the characteristics of gas passing through a gas-lift valve. In the method, CFD calculations numerically ...

A new orifice-measurement standard has recently been published by the American Petroleum Institute (API) whose support, combined with that of the American Gas Association (AGA) and the Gas Processors ...

Complex entrance profiles boost orifice-flow efficiency but at the expense of repeatability. Changes in flow rate through a scuba oxygen analyzer can prove dangerous, even deadly to a diver. That's ...

This article describes how a multivariable pressure transmitter with built-in dynamic compensation can correct for many of the errors and inaccuracies that can occur in differential pressure based ...
