Gas mass flow controllers must be fast and accurate to establish stable flow. Our mass flow controllers reach their setpoints faster than any others, which enables them to suppress fluctuations in line pressure before they affect your process downstream. Customized valve options and factory PID tuning ensure that your MFC will perform well in your specific application.
Pressure based mass flow
instrumentation for top performance.
- 0.6% of reading accuracy on most flow instruments
- 4 ms response time
- No warm up
- Four process variables
- Built in display
- Industrial protocols
- Pressure compensation
- Temperature compensation
- Wide dynamic flow ranges
Performance
- Available ranges: max 0-5000 slpm, min 0-0.5 sccm/0-500 sµlm
- Steady state control range: 0.01% – 100% of full scale.
- Standard accuracy calibration, NIST-traceable: +/- (0.6% of the reading on most products)
- Optional high-accuracy calibration, NIST-traceable: +/- (0.5% of the reading on most products)
- Repeatability: +/- 0.1% of reading + 0.02% of full scale
- Typical control response time constant: 50-100 ms (as low as 25 ms with PID tuning)
- No warm-up time required
