  • Troubleshooting an Alicat device

    Troubleshooting an Alicat device When your Alicat instrument isn’t working as expected, we want to help identify and resolve the issues as quickly as possible. Fortunately, most problems can be fixed without having to return the device to the factory. This article covers common issues with Alicat devices and outlines solutions. Resolving error codes When […]

  • Connecting a CODA to FlowVision 2.0™ tutorial

    Connecting a CODA to FlowVision 2.0™ tutorial In this article, we explain how to connect a CODA meter or controller to Alicat’s graphical user interface program FlowVision 2.0™. This program enables users to easily collect and analyze data from Alicat’s mass flow and pressure devices. Connecting a CODA meter to FlowVision 2.0™ Each package comes […]

    Alarm function (ALE command) tutorial

    Alarm function (ALE command) tutorial Alicat flow and pressure devices have an optional alarm functionality that helps simplify control systems such as PLCs or manned stations. An alarm is transmitted as an analog signal though the communications connector on the device. In systems where an Alicat is not connected to a central system, the alarm […]

    IP address configuration tutorial

    IP address configuration tutorial An Alicat device with Ethernet-based protocols has an IP address to distinguish it from other devices on the network. This can be set either as a static address, or an address determined by a DHCP (Dynamic Host Configuration Protocol) server. The front panel accessibility for this feature makes it possible to […]

    Control deadband tutorial

    Control deadband tutorial The dual valve PCD-Series maintains fast, precise closed system pressure control with minimal gas waste. This stable control is primarily due to a well-balanced PD2I algorithm. However, changing ambient conditions can still cause oscillation loops. Controller deadband creates a ± band of change around the chosen setpoint, minimizing oscillation loops in dual valve […]

  • Configuring an Alicat Display

    Configuring Your Alicat Display The large display on front of your Alicat can be configured to meet specific application needs. Options are available for contrast, backlight on power up, and rotation for upside-down installation. Find your firmware version in the “About” menu on the display or on the calibration sheet. 10v Firmware LCD contrast Select: […]

    Control loop variable tutorial: Changing between mass flow, volumetric flow, or pressure control

    Control loop variable tutorial: Changing between mass flow, volumetric flow, or pressure control An Alicat mass flow controller is usually set up to control mass flow rate, but it can instead be set to control pressure or volumetric flow rate. See below for instructions on how to change the control variable. Video tutorial Step-by-step instructions […]

    Setpoints/setpoint limits tutorial

    Setpoints/Setpoint Limits Tutorial Alicat controllers can accept a setpoint from an integrated display, a serial command, or an analog signal. See below for instructions on how to select a setpoint source, establish a setpoint, and choose setpoint limits to avoid accidental tampering with a process – all via the front display, available with most Alicat […]

    Totalizer Tutorial

    Alicat Totalizer Tutorial: Laminar DP Instruments To operate totalizers on Alicat Coriolis and MEMS thermal flow instruments, see the CODA manual and BASIS manual . While a meter measures the rate of flow at any given moment, a mass flow totalizer measures the total accumulated mass of a particular gas (or gas mixture) that has been […]
