Flow metering and control for high pressure flow systems

There are times when a high operating pressure is needed, and now you can use an Alicat for that high pressure system. It means you can take advantage of all the Alicat benefits you love so much: changing gas types on the fly, multivariate displays, and the controls and speed you depend on for a stable, repeatable process.

You can take a look at the new MQ meters and MCQ controllers for high pressure flow systems on the respective Alicat meter and controller pages. They handle pressures up to 320 PSIA (22 bar), a new upper limit on Alicat flow instrument performance. Minimum operating pressures are 15 PSIA for the meters and 30 PSIA for the controllers.

Like our standard instruments, the MQs and MCQs come equipped with our COMPOSER software, which lets you save up to 20 custom gas mixes (in 0.1% increments), composed from up to five of the 98 standard on-board gas calibrations. And the devices can be ordered in the same full scale ranges as the standard products, so it doesn’t matter if you are flowing less than 0.5 sccm or as high as 5000 SLPM. You can get a meter or controller for your application.

To ensure the highest possible measurement resolution and fastest possible control response times, MCQ high pressure controllers feature valves and sensors ranged to your application. Our standard control response time is less than 100 ms, and with custom tuning you can see performance under 50 ms (ask your application engineer for help with this). With Alicat’s industry-leading control response time, you can be assured that your process will be rock steady, regardless of the disturbances.
