FMA-A2108 is a FMA-A2000 series gas mass flow meter without a display that provides high performance, versatility, and state-of-the-art design in one compact package. The FMA-A2000 series uses capillary-type thermal technology to directly measure mass flow of gases. No temperature, pressure, or square root corrections are required. This model has a linear 0 to 5Vdc and 4 to 20mA output. The FMA-A2000 series is compatible with most non-corrosive gases. The user is advised to check the wetted materials against gas compatibility. OMEGA’s mass flow controller uses an internal electromagnetic proportional valve to control the mass flow rate. A command signal can be supplied either by the internal setpoint pot or by a 0 to 5Vdc external source.
