“A moment of sudden realization, enlightenment, or inspiration.”
– Oxford English Dictionary

At Alicat, we’re always looking to improve our products for our customers. One early distinction in our instruments were those full-information, menu-driven, multi-parameter LCD displays on our meters and controllers. A new development is an illuminated backlight on our monochrome displays. With a new ON/OFF button centered under the Alicat logo, the choice will be at your finger-tips—turn the light on and off as desired. The backlight enhances screen legibility ...

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 ...

Integrate a fast flow controller into your networked system

Posted by:

Ethernet/IP and DeviceNet now available on mass flow controllers, meters and pressure controllers

What’s cooler than having the world’s fastest lab-quality flow or pressure control device?

Did you think, “Networking that baby into an industrial process!”? Well, you read our minds, because so did we! … That’s so spooky!

Connecting flow and pressure controllers or meters to an industrial i/o system is easier than ever with the addition of Ethernet/IP or DeviceNet protocols. This brings the available list of protocols on Alicats to ...

EPC family delivers responsive liquid or gas pressure control, tailored to application needs
Tucson, Arizona (December 7, 2016) – Alicat Scientific has added two new families of electronic pressure controllers specifically for high volume original equipment manufacture. The EPC family with single proportional valves, and EPCD family with dual valves, provide customized pressure control in embedded systems. The small footprint instruments respond quickly to upstream fluctuations to provide fast, accurate control of pressure in an economical, easy-to-integrate package. Alicat ...

Why is my variable area flow meter not matching up with the Alicat?

Posted by:

A Rotameter is a variable area flowmeter (VAF). It provides a flow measurement by using the pressure of a flow stream to float a ball within a conically shaped tube and provides the mass flow measurement of a gas or liquid, when operating in its standard fluid, temperature and pressure environment.

When ordering a Rotameter, one must choose a specific gas, standard temperature, and pressure that it will be specifically calibrated for. If one parameter deviates from these specifications in actual ...

Challenges in Gas Mixing and Dilution Applications

Posted by:

Gas mixing is a science that can present new challenges, even if you think you’ve seen everything. Having the right equipment alleviates many problems, since the end product can suffer if the mixing setup is subpar. It helps to understand the role of each component in a mixing system and how it can improve your process. Starting at the beginning of the process, here are some of the challenges that may arise, and suggestions to help make your gas mixing ...

How Accurate Are Multi-Gas Calibrations?

Posted by:

When you switch from flowing one gas to flowing a different gas in the same flow meter, are the new measurements with the new gas just as accurate as the original calibration gas? As the originator of multi-gas flow meter calibrations some 20 years ago, Alicat is asked this question often. In this post, we’re going to look at Alicat’s approach to gas selection and why you experience no change in accuracy when you change gases on an Alicat mass flow ...

Alicat’s MCE-Series and MCV-Series direct replacements for common industry mass flow controllers
Tucson, Arizona (October 28, 2016) – Alicat Scientific’s mass flow controllers ensure the optimal coating environment in vacuum chambers, maintaining product integrity in coating and sputtering processes. The MCE-Series and MCV-Series may be used to replace legacy and discontinued MKS instruments. Made to fit the same space as common industry mass flow controllers, both series are easy to integrate into existing systems. In use, they offer fast, accurate ...

Even faster leak checking using pressure control loop on MFC

Posted by:

A pressure decay test can take a while, and waiting time is wasted time.

In this video, we demonstrate Alicat’s mass flow controller simultaneously controlling the pressure in the device under test, and monitoring leak rates as low as 2.5 sμlm. The result is an instant quantification of a leak rate, as soon as your system is settled at the target pressure. Nor do you need to do a lot of math to find an average leak rate—you’ll know the leak ...

Considering Hysteresis in Mass Flow Meter Selection

Posted by:

Alicat’s mass flow meters and mass flow controllers are renowned for their speed and accuracy, but how important is our speed to your accuracy? In this article, we look at hysteresis and its effects on common types of mass flow instruments.

Hysteresis reduces your measurement accuracy by causing your meter to respond differently to repeated identical inputs. What is hysteresis? In simplified terms, hysteresis is the tendency of a system to react differently to the same input based on its history ...
