Alicat mass flow and pressure instruments are designed with a variety of features to improve process monitoring and control. Most of these features come standard with the specified flow and/or pressure devices, however optional features are indicated as such. Easy to use, multivariate meters and controllers All flow and pressure devices are available with monochrome backlit […]
What type of fluid can be flowed through an Alicat flow instrument? Alicat devices can be customized to flow a wide range of fluids, however each device has its own unique capabilities. Taking a look at gas flow vs. liquid flow devices can help you get the most out of your instruments while minimizing risk […]
Many processes require corrosive gases like ammonia or sulfur dioxide that cause damage to the instrument. These Alicats are built to withstand tough process conditions; configured to thrive in harsh ambient conditions.
Calibration and accuracy specifications for Alicat devices Each device that goes through an Alicat calibration comes with a NIST-traceable Certificate of Calibration. This guarantees that the device’s calibration can be traced back to primary SI standards such as mass and pressure. As a result, an Alicat device will output mass flow rates that fall within […]
Mass flow controllers have a closed loop pressure feature, able to control pressure or mass flow rate. Simultaneously control pressure and measure flow rate.
High-accuracy multi-gas calibrations using Gas Select™ feature Alicat mass flow meters and controllers can measure or control over 98 gases with NIST-traceable accuracy. In this article, we discuss how an Alicat maintains high accuracy measurements across this wide range of gases. Alicat devices are pre-loaded with 3-dimensional gas properties data Alicat mass flow instruments report […]
Alicat mass flow controllers have control response times as fast as 30 ms. What exactly does that mean? In this article, we discuss Alicat mass flow controller response specifications. Watch this one-minute video to see Alicat’s control response between setpoint extremes: Physical time constant (τ) The physical time constant (τ) is one of the few […]
