Custom Part Number Decoder

Posted by:

Because Alicat instruments are so highly customized, our part numbers get quite long and confusing. Customers often want to reorder a similar instrument or to find out what options are included in a particular one so they can repurpose it. The part number, printed on the silver manufacturer’s label on flow body of your Alicat instrument can tell you a remarkably large amount about what the factory settings were when we shipped it.

Senior Applications Engineer Mike Owen has put together ...

Remote Control of Alicat Instruments with Flow Vision SC

Posted by:

Flow Vision™ SC

Flow Vision SC is Alicat’s Windows® desktop application for controlling and logging data of our flow and pressure control devices. It is versatile and intuitive, with many capabilities—which you might also say about our instruments. It is separate from the COMPOSER™ and Gas Select™ firmware built into our main product lines, Flow Vision apps expand and complement the built-in firmware.

The graphical user interface (GUI) of Flow Vision SC allows for actions as simple as polling or ...

How ambient air monitoring technicians helped craft the FP-25

Breathe in the crisp, frigid air. Feel the snow blowing against your face. Such weather would push most flow standards well beyond their limits of accuracy. Not so for the FP-25. It was tailor-made for these very conditions, thanks to technicians just like you.

This is the story of how ambient air monitoring technicians helped craft the FP-25, Alicat’s new weatherproof flow standard for outdoor air samplers. This instrument is the product ...

Mass Flow Controller Measurement Technology: A Review

Posted by:

All mass flow controllers are made to achieve the same goal, but there are numerous techniques for measuring. Taming the flow rate of a gas stream requires two systems to work in tandem—a control valve, and a flow measurement element. Here are four main types of flow element technology used in today’s mass flow controllers:

Thermal Bypass

Thermal dispersion bypass flow meterThermal dispersion is the Generation X of flow measurement technology; the 1960s and ...

Improved Process Gas Control Optimizes Reactive Sputtering

Posted by:

Customized valve response algorithms in flow controllers produce better films, with more control of the target’s transition state.

Reactive Sputtering

800px-piiid_knee_agtarget_iot-labeled

Reactive Sputtering is a type of Physical Vapor Deposition process used to create thin film vacuum coatings. The process deposits a compound material coating on a substrate by introducing a reactive gas, such as O2 or N2, into a plasma typically generated using an inert gas, such as Argon. The reactive gas is ...
