Storage tanks holding volatile fluids must have reliable level measurements to avoid unsafe overfill conditions. A Control Engineering Asia article, Wireless vibrating fork technology enables Hengyang Petrochemical to implement cost-effective overfill prevention solution, describes how this petrochemical producer sought to reduce the risk of overfill conditions. The plant had existing non-contacting radar level measurement devices […]

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 […]

Backing up your computer or server is a waste of time if restoring the backup fails when you need it. Good practice is to test these backups on separate test systems periodically to make sure they restore properly. Similarly, safety instrumented systems (SISs) need to assure that each safety instrumented function (SIF)/safety loop does what […]
