FMA-5000 Series electronic
mass flowmeters combine high
performance and versatility into a
state-of-the-art, compact package.
These flowmeters measure the
mass flow rate of gases in 13 ranges
from 0 to 10 SCCM (standard cubic
centimeters per minute), to
0 to 50 SLM (standard liters per
minute). For the complete listing of
ranges, see the “Flow Range Table”
on the next page. Accuracy is
1.5% FS over a wide temperature
and pressure range. Time response
is 2 seconds to within 2% of final
flow. These unique flowmeters are
available with (FMA-5600) or
without (FMA-5700) digital display.
The display is a 31⁄2 digit LCD, tiltable
to 180°. An optional power supply
(12 to 24 Vdc) can be purchased
separately (see “Accessory”).
With their analog output,
integral/remote digital display,
insensitivity to temperature and
pressure variations, and low cost,
the FMA-5600 meters are ideal
substitutes for rotameters; they can

also be used to calibrate rotameters.
Other applications include chemical
and food processing, research and
development, gas chromatography,
and leak and filter testing.
A 0 to 5 Vdc (standard) or 4 to 20 mA
(optional) output signal is linearly
proportional to gas mass flow rate—
for recording, data logging, or
control. A 9-pin “D” subconnector for
the output signal, input power, and
remote display drive is supplied
with its mating connector for all
FMA-5000 Series units.
All wetted surfaces are constructed
of corrosion-resistant glass-filled
nylon 66 plastic, 316 SS, and FKM
O-rings. Ordering option “-ST”
replaces the FNPT-ported nylon
flow body with a 316 SS flow body
with 1⁄4" compression fittings for
tubing. (The “-ST” option is available
on the FMA-5600 display unit only.)
The plastic flow body is suitable for
use with non-toxic, non-flammable
gases; the 316 SS flow body is
suitable for higher pressures and
hazardous gases.

The FMA-5000 Series flowmeters
measure molecular flow—the
measurement of concern in most
applications, including chemical
processing, combustion, and
heating or cooling. No temperature
or pressure corrections are
required, unlike with most other
volumetric flow monitoring devices.
The flowmeter is operated by 2 RTD
coils around the sensor tube, which
direct a constant amount of heat
into the gas stream. The gas mass
flow carries heat from the upstream
coil to the downstream coil. The
resulting temperature difference
(T2 - T1) is detected by the RTD
coils, producing the output signal.
