Learning the basics can ease loop tuning frustration and ensure stability. During plant operations, it seems that tuning control loops is an ongoing task, which can be a continual frustration to ...

Equipment designers find that proportional control technology is ideal where precise performance is required in variable pressure or flow applications. Often perceived as more complicated than other ...

The flow of all fluids, whether liquid or gas, will have one of three states: laminar, turbulent, and transitional. This article discusses flow principles and pressure-based flow measurement. Laminar ...

Choked flow in control valves is a subject of serious concern for industrial users. The term is usually associated with destructive process conditions that can damage valve internals or expose ...

When refrigeration systems are exposed to low outside air temperatures, the condensing pressure will fall, and if the head pressure gets too low, the metering device will not have enough pressure drop ...

When refrigeration systems are exposed to low ambient conditions, the condensing pressure (head pressure) will fall. If the head pressure gets too low, the metering device will not have enough ...

It'll fly instead using Active Flow Control (AFC), using a series of nozzle arrays along the wings connected to a pressurized air system, capable of blowing controlled bursts of air that can directly ...
