"If we can catch it in time we can shut the downstream equipment down in a controlled way, resolve the blockage and start back up quickly. That saves time and product.
But if we don't know that a blockage is developing, then the first sign of a problem is often after it's serious. It's not unusual to spend four hours trying to clear an impacted blockage, get systems cleaned out, discard questionable product and start things back up."
That's the way a process control engineer for a F100 food company describes their challenge - and it's the power of Auburn's flow control technology which uses particle speed measurement techniques.
Triboelectric instruments can be used to measure particle velocity in pneumatic conveying, but sometimes all that's needed is a simple indicator - everything's moving, it's slowing down, and/or it's stopped.
Auburn offers simple flow/no flow monitoring (it's moving or it's stopped) as well as slowing down. Using particle speed measurement we can provide engineers, production and maintenance teams advanced warning of a blockage - and give them the precious time to either intervene and prevent a problem, or to resolve it faster.
Another common requirement has to do with bulk unloading. As delivery trailers, rail cars or other means empty, the resulting high volume of air and low volume of particles can damage equipment. Monitoring the rate of flow provides advance warning to operators to prevent equipment damage.
