Differential pressure (DP) is one of the most used and proven technologies for flow measurement. With averaging pitot tube (APT) technology, the impact pressure is sensed on the front of the device as the flow initially approaches the obstruction or bluff body which creates the pressure difference. For the most accurate measurement possible, it is […]

One of the most proven ways to measure flow rate is through differential pressure measurement. By creating an obstruction in the flow of fluid, a difference in pressure is created upstream and downstream of the obstruction. In this 3:12 educational YouTube video, How Differential Pressure Flow Works, Emerson’s Rosemount Measurement team illustrates how differential pressure […]

The ways to measure gas and liquid flow are numerous. In prior posts, we’ve highlighted Annubar technology, which is similar to pitot tube technology. From Wikipedia: The biggest difference between an annubar and a pitot tube is that an annubar takes multiple samples across a section of a pipe or duct. In this way, the […]
