The FMA-A2000 Series electronic mass flow meters/controllers provide high performance, versatility, and state-of-the-art design in one compact package. The FMA-A2000 uses capillary-type thermal technology to directly measure mass flow of gases. No temperature, pressure, or square root corrections are required.
