Knowledge on demand - Part 1

Tapping into better, faster, more useful process information—for wiser decisions—can be easier than you think.

Knowledge on demand

We all know reach can exceed grasp, but at least in accessing and using process control information, many longtime hurdles are shrinking. Finally, knowledge-on-demand is closer at hand—physically, if not always mentally.The old chasms were often huge between plant-floor operations and other applications, such as utilities where production data is generated and central locations where users make decisions to improve their processes. Historically, this is because reaching many remote signals and parameters on legacy equipment was difficult, and establishing the networking and programming needed to get information back to users could be even harder.Fortunately, many…

Vortex flowmeter calibration and rangeability

How can we determine the best size to balance accuracy against pressure drop?

Q: I have a question regarding vortex flowmeters and hope that you can clear it up. The line size is 3 in.; the flow is minimum 6 m³/hr, normal 20 m³/hr, maximum 22 m³/hr. The vendor suggested using a 3-in. Endress+Hauser (E+H) Prowirl vortex flowmeter with minimum flow 4.03 m³/hr, maximum…
