OMEGA FMA 5400 5400, FMA 5500 5500 Mass Flow Controllers User's Guide

FMA 5400/FMA 5500 Mass Flow Controllers are designed to work with clean gases only. Never try to meter or control flow rates of liquids. The FMA 5400/5500 Mass Flow Controllers are capable of a full open condition for the valve, regardless of setpoint conditions. The FMA 5400/5500 transducers require a +12VDC (+24VDC optional) power supply with a minimum current rating of 800 mA to operate.
