With the old mechanical displacers, level fluctuations ran 4-in to 5-in with a lot of hysteresis and frequent failures, causing operators to control at much higher levels than were optimal. New magnetic technology is changing all that. Here's how.
With the growth of wind farms, users are turning to condition monitoring and automatic lubrication systems for increased reliability.

Wireless technology is enabling INEOS Köln GmbH (Cologne, Germany) to detect blocked filters in polyethylene pellet transportation tubes that can lead to production downtime at its plant in Cologne.
Gulf Chemical & Metallurgical Corporation (Freeport, Texas), a subsidiary of the Eramet Group, is a recycler of spent petroleum catalysts and a leading producer of ferroalloys. The company applies hydrometallurgical and pyrometallurgical operations to recover molybdenum, vanadium, nickel and cobalt for reuse by major catalyst producers and steel manufacturers. Embarking on the road to improved equipment reliability represents a key aspect of a concerted strategic initiative for Gulf Chemical. The introduction of wireless technology and additional support has yielded successful outcomes for its facility.
If pump cavitation is not detected and quickly eliminated, significant damage can occur to the impeller and other internal components. Since cavitation (the formation and collapse of vapor bubbles in the pumped fluid as it passes through the pump impeller) is often temporary or even induced by the process, timely knowledge of the condition is extremely important so operators can act to alleviate the problem and prevent damage.
In my opinion, the system curve is the single most important component of the pump selection process. After all, the system curve determines the operating point on a pump’s performance curve.
