Alicat has the opportunity to work with all kinds of engineers and scientists pushing the boundaries of science and technology in aerospace applications. Projects include improving pilot safety, putting satellites into space, launching rockets, and much more. Our goal is to understand each customer’s distinct application requirements and find the perfect mass flow or pressure […]
Placing pressure control devices upstream of the chamber in vacuum coating applications saves time, cost, and increases accuracy in vacuum deposition tools.
One of our customers needed a way to control the pressure in a reaction chamber between -200 to +200 cmH2O. While the customer’s building had an ample supply of compressed air, they had no vacuum source. Without suction, they were unable to reach negative gauge pressures. They reached out to Alicat in search of a […]
A common application of Alicat’s mass flow and pressure devices is the characterization of a static device with pressure drop, such as a filter or static orifice. Filters and static orifices have pre-defined curves for the relationship between pressure and flow rate. A customer will most likely want to develop this curve or test a […]
One of our customers developed a go/no-go test where he would check the diameter of a female fitting to ensure proper engagement of the male counterpart. At the time, he was using a pin gauge to measure the diameter of the test part. This setup was both slow and unreliable, so he contacted Alicat to […]
Looking for a fast, accurate way to leak test your system? Whisper low pressure drop controllers provide a convenient, single instrument solution. A standard controller may also work, however stable leakages are best detected when the meter generates minimal pressure drop (line pressure due to frictional resistance). This makes the low pressure drop (as low […]
Gas chromatography (GC) is an important analytical technique used to separate and analyze chemical components in a mixture. Here, we provide a brief introduction to GC and discuss some of the common application challenges and mass flow/pressure solutions. How does gas chromatography work? The sample is first injected into the inlet of the GC, where […]
Let’s take a look at how optical fibers are manufactured, and where Alicat mass flow controllers and meters fit into the picture.
Variable area flow meters, commonly known as rotameters, use the pressure of a flow stream to determine a volumetric flow measurement. The pressure causes a ball within a conical tube to float, and the height is directly correlated with the flow rate of the gas or liquid. When operating in standard fluid, temperature, and pressure […]
