FQB2 Mass Flow Controller
Brand: Proportion-Air, IncThe FQB2 Mass Flow Controller is another complete flow control package from Proportion-Air.
The FQB2 electronically modulates the pilot of any of a variety of mechanical flow amplifiers (Generally, the PSR-Series).
Proportion-Air selects the appropriate mechanical flow amplifier based on your specific application’s flow control parameters.
An F-series air flow transducer is used to feed an electronic signal representing the mass flow rate of air back to the FQB2 control valve circuit.
This makes a complete flow control package which electronically controls the flow of air independent of supply pressure or varying system restrictions.
The FQB2 mass flow controller has a standard turndown ratio of 10:1 – Ask about our 20:1 turndown ratio option.
