One of the most important things for users when it comes to controllers, is the possibility to select and change their preferred control method for a particular experiment or application. Not only can the instrument control on flow (mass or volumetric) whilst measuring and outputting the pressure but, by means of the front panel interface, the instrument can be instantly changed to control on pressure whilst measuring and reporting the flow.
To achieve the same, other solutions on the market require a combination of several more instruments, with the complication of convoluted wiring leading back to a control panel, PC or lap-top. Not only is such a solution relatively expensive and time consuming to configure, but it is also fixed in its control mode and more limited in its capability. Traditional methods might include manual pressure regulators and mechanical flow measurement devices, but these are affected by changing ambient conditions, require constant vigilance, and provide no data-logging capability.
Alicat’s products innovative technological features can be seen within the following application example. Reaction vessels require the addition of gases under a controlled pressure regime within such industries as chemical, pharmaceutical and biotechnology, to name but three. Multiple gas species are common-place, across a wide flow regime, with accuracy and precision often being important – especially for characterization within research and development. Rapid control response and accuracy across a broad range of gases is often critical to a successful process. Standard features of Alicat product line are of great assistance to this application.
All told, single-instrument measurement and control of flow and pressure are available within open flow and dead-ended systems for applications across a whole host of process industries, research, and development. These standard instruments employ time-proven, unique technology advantages to reduce cost, improve yield and save time within gas dosing and/or batching processes.
