  • Creating a flow standard for harsh environmental conditions

    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...

  • Mass Flow Controller Measurement Technology: A Review

    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 is the Generation X of flow measurement ...

  • No flashlight required

    “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/O...

  • Improved Process Gas Control Optimizes Reactive Sputtering

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

  • I Accidentally Had the Wrong Gas Selected. What Can I Do?

    In brief:  Both the mass flow rate and volumetric flow rate depend on the viscosity of the gas. If a different gas is selected than that which is flowing through the device, the flow rates will be off by approximately the ratio of the viscosities.  Simply multiply your reading by the ratio of the selected gas’s viscosity to the desired gas’s viscosity. Discussion and example: Both the mass flow...

  • Alicat Adds EtherNet/IP and DeviceNet to Controllers and Meters

    Industrial automation protocols integrate mass flow and pressure instruments into process scheme Tucson, Arizona (December 14, 2016) – Alicat Scientific has expanded its communications protocol offerings, adding EtherNet/IP and DeviceNet as options on its line of mass flow, pressure, and liquid instrumentation. The new industrial automation protocols enable integration of Alicat instruments with ...

  • Integrate a fast flow controller into your networked system

    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 ...

  • Customized Electronic Pressure Controllers for OEM Use from Alicat Scientific

    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...

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

    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 i...

  • Challenges in Gas Mixing and Dilution Applications

    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...

  • How Accurate Are Multi-Gas Calibrations?

    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 a...

  • Accurate Mass Flow Control Improves Vacuum Coatings Results

    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.

  • Considering Hysteresis in Mass Flow Meter Selection

    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...

  • 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 press...

  • Mass flow measurement techniques across the spectrum

    A few flow measurement principles dominate the flow technology landscape, but there’s a rich variety of ways to measure flow that might not make themselves apparent without a bit of research. Anyone who works with flow is likely to be familiar with thermal flow meters, differential pressure-based flow instruments, and rotameters, so here is a look at a few flow technologies you may hear less about...
