Downstream or low-side pressure reading.
kPa
Differential Pressure (delta P)Positive differential pressure
100kPa

Pressure difference between the two measurement points.

High-side Pressure (P1)300kPa
Low-side Pressure (P2)200kPa
High-side (P1)300
Low-side (P2)200
Delta P100

Delta P = 100.0000 kPa

  • The pressure drop is 100.0000 kPa.
  • A positive delta P confirms that fluid is driven from the high-side to the low-side as expected.

Next stepApply the differential pressure to control a valve, actuate a switch, or infer a flow rate using a flow element calibration curve.
