Across many industries, level measurements are critical ones for safe and reliable operations. This is true for the water and wastewater industries. The choice of technologies for these measurements is broad, especially since they fall into two categories point-based (on/off switching) and continuous. In a Water Online article, Point Versus Continuous Level Measuring Technologies, Emerson’s […]

Safety instrumented systems (SIS) include the sensor(s), final control element(s) and logic solver(s) for each of the safety instrumented functions (SIFs) in the SIS. To verify the SIFs are performing the amount of risk reduction intended for their application, they must be periodically proof tested. PCN Europe magazine interviewed Emerson’s Teddy Tzegazeab on how proof […]

For electrical power producers, the phrase “heat rate” refers to the efficiency of the power plant. It is defined as the thermal energy in divided by the electrical energy out. Emerson’s Lydia Miller let me know about a new whitepaper, Using Automation to Improve Plant Heat Rate that highlights ways to improve the efficiency of […]
