GFC series gas mass flow
controller
product manual:
Flow measurement range up to 1000L / min, pressure resistance to 500psi, and NIST traceability certificate available
The GFC series gas mass flow
controller combines a throttling device and a straight tube
sensor to measure flow accurately and reliably. It is not affected by changes in temperature and pressure. GFC mass flow
controller with PID adjustment and control valve can keep the flow constant. The flow set point can be set on the spot or remotely by potentio
meter with 0-5VDC or 4-20mA signal. Adopt 3 and a half digital display gas flow, LCD display can be rotated 90 degrees. Use with GFT Sydney Flow Totalizer to accumulate flow. GFC comes with a NIST traceability certificate.
