Each MFS-2 is calibrated against highly accurate mass flow standards. It can be used in push or pull mode. 

The MFS-2 mass flow generator's operation relies on modulating a diaphragm pump in order to create the set mass flow rate. Ultra-efficient PID (proportional Integral Derivative) control is used for quick response to setpoint changes and minimal variation from the setpoint. As a result, the pump works only as hard as it has to, greatly reducing pump wear, power consumption, and noise. 

The same friendly, intuitive menu-driven system, backed up by non-volatile memory, as used in other Sable Systems products, operates the MFS-5 mass flow generator. It features both analog and serial outputs for easy connection to a data acquisition system. It is fully computer-controllable via its serial port. It also features a user-configurable alarm to alert users locally and (optionally) remotely if a fault develops. It is powered from 12 VDC (universal adapter supplied) and can be operated from an optional battery pack for field use.

Accurate flow control is vital in applications such as respirometry, and the MFS-2 mass flow generator, which requires no temperature or barometric pressure correction because it generates a mass or molar flow rate already corrected to STP, is an excellent choice for research-grade low to medium flow rate applications.
