Alicat LC-Series Liquid Flow Controllers

Alicat LC-Series Liquid Flow Controllers rapidly reach setpoints and maintain stable control of liquid volumetric flow rate or pressure, and simultaneously measure live flow, pressure, and temperature readings.

Features of Alicat LC-Series Liquid Flow Controllers

• Fast control, multivariate data. Millisecond-response times immediately upon powering up, to control either mass flow, volumetric flow, or pressure and display instantaneous flow, pressure, and temperature readings, in your choice of engineering units.
• Easy integration. Custom process ports and electrical connectors, and your choice of EtherNet/IP, EtherCAT, DeviceNet, PROFIBUS, PROFINET, Modbus (RTU and TCP/IP), or serial communications for easy integration into your industrial process.
• Multi-variable process measurements: Simultaneously measure volumetric flow, liquid pressure, and liquid temperature.
  User changeable units of measurement: Change the unit of measurement for pressure, flow, or temperature from our extensive list of engineering units.
• Monochrome backlit LCD with integrated touchpad: Easily read measurements using the backlit display and control configurations with the user-friendly integrated touchpad.
• User-adjustable setpoint ramping & limits: Configurable ramp rates allow the process variable to be controlled as fast or as slow as desired, and configurable setpoint limits protect processes from inadvertent setpoint changes.
• Valve close override and valve open override: Utilize alarms to quickly vent your system or stop all flow as needed.
