LC–Series: Liquid Flow Controllers
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.
- 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.

Device Features
Included with each device
- 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.
