0 - 500L/min
The FMA1844 Series electronic gas mass flowmeters provide for monitoring the flow of a wide variety
of gases from 0 up to 500 L/min. Utilizing heat transfer through a heated tube to measure molecular gas flow rate, the
FMA provides measurement of direct gas mass flow rate, without the need to compensate for variations in gas temperature or pressure.
The FMA1800 series has both an integral digit display and analog output. The display is tiltable over 90 degrees for viewing convenience.
The FMA1700/1800 Series require 12 Vdc power @ 200 mA maximum, provides a mating 9-pin “D” connector
with 3 feet of ribbon cable for accessing the 0 to 5 Vdc output signal and power input connections (use FMA178C-MA for 4 to 20 mA output signal connection)
