Mass Flow Controllers & Meters

Mass Flow Controllers

Gas mass flow controllers must be fast and accurate to establish stable flow. Alicat 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 mass flow controller will perform well in any application.

Laminar, differential pressure-based mass flow controllers for top performance include:

  • 0.6% of reading accuracy on most flow instruments
  • 10 ms response time
  • No warm up
  • Four process variables
  • Built in display
  • Industrial protocols
  • Pressure compensation
  • Temperature compensation
  • Wide dynamic flow ranges
