Series GFC Gas Mass Flow Controller
Brand: Dwyer Instruments, LLC
The Series GFC Gas Mass Flow Controllers combines a straight tube sensor with a restrictor flow element.
It is available for flow ranges up to 1,000 L/min and offered in aluminum or 316 SS in 1/4", 3/8", 1/2" and 3/4" sizes.
Features- Provides High Accuracy and Repeatability
- Flow rates are virtually unaffected by temperature and pressure variations
- Utilizes an electromagnetic valve and PID electronics to maintain continuous control by comparing measured sensor signal set to flow rates
- Set points can be adjusted with local potentiometers or remotely via 0 to 5 Vdc or 4 to 20 mA Analog signal
- Actual gas flow is displayed in engineering units on a 3-1/2 digit, 90° tiltable LCD readout
- Can be used with Series GFT2 Flow Totalizer for applications requiring totalization
- NIST Traceable Certificate Included
