Mass Flow Meter Displays 23 Engineering Units

The FMA-4100/4300 series meter can display flow rate in 23 different volumetric-flow or mass-flow engineering units, including a user specific selection. The flow meters offer various functions including programmable flow totalizer, high and low flow alarm, automatic zero adjustment, and two-relay outputs. In addition, jumper-selectable 0- to 5-Vdc or 4- to 20-mA analog outputs, status LED diagnostics, storage of up to 10 different gas calibrations, and internal or user-specific K-factors are also offered. The digital RS232 or RS485 (optional) interface provides access to applicable internal data including, flow, CPU temperature, auto zero, totalizer and alarms settings, gas table, conversion factors and engineering units selection, dynamic response compensation, and linearization table adjustment. Automatic sensor zero-offset adjustment occurs via a digital interface or local push button. Pricing for the FMA-4100/4300 series flow meter starts at $730. OMEGA ENGINEERING INC., Stamford, CT.
