The Alicat Scientific LC Series Liquid Flow Controller utilizes a proportional valve coupled to a flow meter body creating a unique closed-loop flow controller system. The integral PID controller positions the valve according to the flow set points. These devices accept a selectable analog or digital control signal from either external devices or locally. RS-232, 0-5Vdc, 0-10Vdc or optional 4-20mA input and output are available standard. Other communications protocols are available. LC Series Liquid Flow Controllers can be configured for single or dual output voltages and/or process signals such as flow and temperature or pressure. The LC Series has a dynamic digital display that simultaneously shows all the measured parameters within the meter plus a push button operator interface allows the user to select a specific parameter for the main display, make set point and control adjustments or tare the meter.
All Alicat LC series liquid flow controller calibrations are NIST traceable.
