Alicat's standard lines of mass flow controller and mass flow meter products are an easy to use and benefit-rich, laminar alternative to more common thermal flow meter and thermal flow controller instruments. The versatility of our gas flow meter and gas flow controller devices is reflected in their numerous standard features. Dynamic graphical displays with mass flow, volumetric flow, pressure and temperature data, RS-232 serial output and your choice of an additional analog or current output are all standard. The display also supports easy selection of one of 30 built-in standard gas calibrations for diversified use in lab and field environments. All Alicat flow controllers and pressure controllers also include field adjustable access to the terms of the PID loop controlling, allowing for easy and precise adjustment of the control response time based on your application. Alicat liquid flow meter and liquid flow controller lines were designed with laboratory and process automation in mind. These devices utilize the same principles of laminar flow that are used in Alicat mass flow meters and mass flow controllers. Alicat liquid flow meters and liquid flow controllers are available in a variety of ranges. We at Alicat firmly believe that our success and growth are a direct result of our commitment to our customers. We endeavor to offer our customers a high tech mass flow product that is easy to use while delivering reliable, repeatable, accurate and complete process measurement data. If a customer has specific application requirements or custom product needs, we listen and respond. Simply put, the paramount goal of Alicat Scientific is to deliver what the customer requires in a timely and affordable manner. Alicat has spent the last 20 years setting the standard for mass flow devices and continues to raise the bar. We at Alicat are committed to our customers and we measure our success based on yours.

In a recent study, researchers Karl Haase and Nicholas Gianoutsos studied a practical way to measure greenhouse gas leaks from orphan oil and gas wells by placing a sealed chamber over the leak and directly measuring the gas flowing out.

They showed that, with the right chamber sealing and setup, this approach can reliably measure very small leaks and track how emissions change over time, even under real outdoor conditions.

During testing, an Alicat mass flow controller was used to introduce known air flows into the chamber, helping the researchers validate and compare the chamber’s measurements.

Check out the full paper here:

Abstract. This study evaluates the performance of a rigid gas flux chamber equipped with a mass flow meter (MFM) for measuring gas emissions from leaking orphan wells and similar pressure-driven gas point sources. We conducted a series of laboratory and field experiments to evaluate the sensitivity,...

Our Applications Engineers deserve a break. We asked Kris Kringle if he could cover the phone lines so our team could get some rest the day after Christmas, but he said, “I don’t know the first thing about fluid dynamics and that’s literally my only day off.”

We appreciate his honesty and will be closing our U.S. office on December 25th and 26th. Our highly qualified flow experts will be happy to assist you on December 27th when they return.
