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 […]

According to an ISA presentation given by Process Automation Hall of Fame member, Greg McMillan, the most common measurement device is the differential pressure (DP) transmitter. It is most commonly used in level and flow measurement. Measuring the differential pressure across an orifice plate is the common way to measure flow. Wikipedia provides a quick […]
