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 […]

Emerson’s Joel Lemke, Bob Sabin, and Scott Pettigrew presented Instrumentation and End Devices Needed for Improved Boiler Operation at the 2012 Emerson Exchange. Their abstract: While boilers are critical to plant/mill operation and business results, their performance is often not ideal. Poor combustion results in higher fuel costs and increased emissions. Lack of reliability and […]
