Poor control performance makes itself evident primarily when a controlled variable (process variable) ... such as mill or feedwater heater level control, drives a valve or damper directly, ...

Multiple input control attempts to manipulate a single process variable to maintain several controlled variables within appropriate ranges. For example, the boiler steam outlet valve may be computed ...

As such, it is normally the variable of first choice as an MV for any higher-level control strategy, especially for an APC controller. There are some exceptions. Although flow is a true extensive ...

In SIGMATEK's web-based visualization tool, the LASAL VISUDesigner, two new controls are available to make life easier for the user: the Data Logger for process analysis and the Interpreter for ...

The flow meters feature coreless air coils which generate a stable, temperature independent magnetic field. This, combined with a continuous, free-flowing measurement tube without constrictions or ...
