As both mass and volumetric flow readings are provided by Alicats, it gives you the freedom to choose the parameter that you wish to measure or control depending on what is required in your application.
Batch function tutorial If you have a controller with the totalizer feature, you have the ability to set a batch fill. This allows you to set a specific total volume and a setpoint at the same time. Whether controlling flow or pressure, the device will hit the setpoint and automatically stop flow once the given […]
Python and command prompt communication instructions These Python drivers are compatible with Alicat mainline instruments only (M/MC, P/PC and L/LC). Setup Alicat Python and Python-driven command prompt (Windows Powershell) drivers have been developed principally by Pat Fuller at NuMat Technologies. Download the drivers from github.com: https://github.com/numat/alicat. In order to run the command prompt/Powershell driver, Python […]
Serial communication tutorial For BASIS and CODA devices, please refer to their manuals. Most Alicat instruments equipped with RS-232 or RS-485 serial communications can be communicated with via ASCII commands. The tabs below cover the basics of Alicat’s serial data frame and serial commands. For more details, download the complete Serial Communications Primer. Note: You […]
STP/NTP Tutorial: Alicat Laminar DP Mass Flow Instruments Standardized flow references define the temperature and pressure conditions used to calculate flow readings. This allows flows measured under different conditions to be expressed according to a common standard, keeping readings accurate and comparable. Unless otherwise requested, your mass flow instrument will ship with a default STP […]
Correcting flow data after choosing the wrong gas in Gas Select™ Selecting the correct pre-loaded gas calibration is an important step in obtaining accurate mass flow data when using Alicat’s laminar DP mass flow meters and controllers. If you do notice you have been collecting data with the wrong gas selected, there is no need […]
Learn how to configure PuTTY to communicate serially with your Alicat flow or pressure instrument.
PID tuning is a type of valve tuning that adjusts how the valve(s) on your Alicat flow or pressure controller responds to the setpoints that you command.
Gas flow controllers and meters are designed to flow only gases, but accidental liquid ingress into a gas flow device can happen in most environments. Depending on the specific flow devices at hand, liquid ingress may be a minor inconvenience, or may result in requiring a whole new set of devices. Here, we explain what […]
Cleaning the outside of your device To clean the outside of your device, use a gentle electronics cleaner and a microfiber cloth. For tougher stains or residues, apply isopropyl alcohol to the cloth. The video below demonstrates how to clean the outside of your device. Cleaning the inside of your device Sometimes the inside of […]
