SHARE

The Flow Controller FC500-FC is an airflow test measurement and flowrate control solution which: Combines the flow measurement, flow control, and logging functionality of the FC500 with a multiple sonic nozzle array, can measure flowrates and control flowrates through the included sonic nozzle arrays, operates as a stand-alone devices or connects to a PC for remote logging and monitoring.

High mass flow accuracy (ranges from ±0.54% to ±0.17%)

  • 2 analog and 2 configurable digital outputs
  • Self-contained package including instrumentation

The embedded software in the FC500 takes the measurements received from its on-board instrumentation and performs the necessary calculations to compute a flow rate. In mass flow controller mode it is also capable of controlling flow rate to a setpoint sent via analog signal or digital control. The software also contains all of the calibration and configuration information needed to perform its required test. The controller software on a customer-provided PC is used to setup a given test and input the calibration coefficients for a given set of hardware. This data can then be transferred to the FC500 hardware. The software can also be used as a data monitor to view current conditions and flow rate.

In addition, this configuration requires that the customer provide both compressed air and 24vdc power to actuate the solenoid valves, which are supplied by Flow Systems.

This unique functionality allows the FC500-FC to act as a stand-alone Flow Controller. Users configure the setpoint (flow) range and the response characteristics and then the FC500-FC will adjust the flow to match the setpoint value. Optionally, Automated Pressure Regulation is available to increase resolution and minimize the effect of upstream pressure fluctuations.

The following is a list of options available for the FC500-FC:

  • 11Mb internal data storage
  • System check standard
  • Humidity sensor (atmospheric air)
  • Dewpoint sensor (compressed air)
