Values of this expression for typical published FBBV C values range from 0.10 to 0.25, clearly exceeding the threshold value. A second challenge related to the ultrahigh capacities of these valves is ...

Oil field operators can use several practical equations for calculating flow rates of natural gas through venturi gas-lift valves. For critical flow, this analysis derived such equations from a ...

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 ...
