Flow measurement is critical in fiscal measurement applications from custody transfer to allocations between parties. The choice of technologies is broad and dependent on the fluid being measured and properties of the application. In an Applied Automation article, Selecting flowmeters for natural gas, Emerson’s Dan Hackett describes the need for different flow measurement technologies across […]

Urea is a key component in nitrogen-rich fertilizers. Typically, the urea production process begins with hydrogen from natural gas and nitrogen in the air to produce ammonia. Urea is produced from the combination of ammonia and carbon dioxide. Urea producers must balance throughput with efficiency and the quality of the urea produced. In a new […]

For those here in North America, there is a good chance you’re braving extremely cold weather today. The Weather Channel captures the situation well in a post, Arctic Cold Blast Continues; Wind Chill Alerts For Over Half U.S. Population. And Canada makes this appear balmy. Back at the Emerson Exchange conference in Orlando this past […]

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 […]
