  • What Is the Definition of Differential Pressure

    Differential pressure can be measured as absolute pressure or gauge pressure It is important to know the difference between the two when using the information in measurements or calculations Absolute pressure is the sum of atmospheric pressure and the gauge pressure measured Gauge pressure is the measurement read from the gauge.
