Liquid-level control, however, has characteristics distinctly different from those of the previous loops. Some of the differences are these: Liquid level is usually a non-self-regulating (integrating) ...

The vessel treating the oily water had frequent high- and low-level alarms, and the overall reliability of the system was poor. The control strategy used a cascade control loop with the level ...

The signal level control didn’t seem to do much ... It uses coax for the loop and configures it like a Mobius strip so that it is kind of, an infinite loop. At the bottom is a balun with ...

Many applications will work with on-off, closed-loop control using an analog sensor measuring temperature, pressure, level, or flow as an input to control a discrete output. The same analog sensors ...

A load upset response like that depicted in Figure 6.1d is somewhat unusual for most processes, but is typical of the load upset response of level control loops. One well-known criterion for ...
