7v Firmware Update Makes Interface More Intuitive for Alicat Flow and Pressure Instruments

Posted by:

We’ve just made it easier to use your Alicat mass flow meters and pressure controllers from their front panels. This post has all the details on our 7v firmware update, which features a more intuitive user interface.

If you’ve been with Alicat for very long, you’ve seen us add new menu selections to our flow and pressure instruments from time to time. We incorporated these features into a set of “Miscellaneous” menus (MISC1 and MISC2) in order to preserve the existing ...

Customer Experience: Ethernet/IP

Posted by:

Most customers don’t call us for our razor-sharp wit, or our slightly eccentric social skills. Instead, we know with certainty that whenever a customer comes to us, they have a problem that needs to be solved. While Ethernet/IP™ is not required for every process, some customers insisted on it. We recently added Ethernet/IP to the list of available communication protocols that can be configured on any mass flow, liquid, or pressure device. We wondered what the most significant benefit was ...

The RS-232 Communication Protocol and your Alicat instrument

Posted by:

The 55-year-old RS-232 protocol is the default method of talking to Alicat devices. Aside from RS-232, you could configure your instrument with RS-485, Profibus DPV1, ModBus RTU, DeviceNet, and Ethernet IP protocols. For the bulk of our customers however, the tried and true RS-232C communication standard will remain the go-to method for commanding and reading Alicat devices.

The Not-So-Standard RS-232 Standard

One of the main reasons that RS-232 has survived for over five decades is that it is a useful, but low ...

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 ...

3 reasons why Alicat is the fastest flow controller company in the world

Posted by:

Building the fastest mass flow meters/controllers and pressure equipment in the world is both a point of pride for us and a unique factor for which our customers select Alicat instruments. The question is, ‘fastest’ in regards to what? Having started working at Alicat Scientific recently, I’ve found these three things which help make Alicat the fastest flow controller company in the world.

Reason #1. Fast Sensor Response Times

Alicat devices have the fastest response time compared to any other flow ...

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 ...
