Pressure Differential

Definition - What does Pressure Differential mean?

Pressure Differential is also called as Differential Pressure. It is defined as the difference between the higher value of force that a flowing fluid exerts on a unit cross sectional area and the lower value of force that the same fluid exerts on unit cross sectional area. In simple terms, a pressure difference is the amount of pressure or force between two points.

Engineers and field operators make sure to keep measuring Differential pressure at various locations of a well as this parameter is one of the important parameters to know so that adjustments can be made to keep the crude production process efficient when an oil or gas well goes live. A simple method to understand the pressure difference across the crude oil pipeline or in any other liquid carrying pipeline is by noting down the pressure readings inside the pipeline as well as outside the pipeline. If the difference in the pressure reading is within the permissible limits, there is no course of action, however, if it is not, then any mechanical means has to be used to balance the differential pressure.

A commonly used instrument to measure pressure difference is “Differential Pressure Gauges”.
