Pneumatic Solutions for Digital Mass Flow Controls
In the early years of process controls, engineers were forced to rely on flow meter tubes and needle valves to control gas flows. Many applications require critical, precise variations of gas control, prompting an ever-growing need for more accurate and repeatable ways of controlling flow and/or pressure of a gas. The first attempts at electronically controlling gases were electronic units controlled with an analog signal to a board controlling various valves. These units featured greater control when compared to the needle valves, but still had problems with accuracy. Process engineers now have more accurate, reliable solutions with advancements in flow and pressure sensors coupled with new valve technologies.

Digital Mass Flow Controllers feature microprocessor capabilities that allow for either analog or digital input, and provide analog or digital output with memory capability. Accuracy has been dramatically improved over the years—Digital and Analog Mass Flow Controllers now provide process engineers with the immediate benefit of an accuracy and repeatability to meet the demanding applications of today.
