ATTITUDE SENSITIVITY: 1% shift for a 90 degree rotation from horizontal to vertical;
standard calibration is in horizontal position.
OUTPUT SIGNALS: Linear 0-5 VDC (2000 Ω minimum load impedance); 4-20 mA
optional (50-500 Ω loop resistance); 20 mV peak to peak max noise.
COMMAND SIGNAL: 0-5 VDC (200K Ω input impedance).
TRANSDUCER INPUT POWER: FMA 1400 ranges up to 10 L/min:
(15 sLit/min max) +15 +
5% VDC, 80 mA max, 1.2
watts max; -15 +5% VDC, 200 mA max; 3 watts max;
FMA 1400 ranges above 10 L/min:
(100 sLit/min max) +15 +
5% VDC, 80 mA max,
1.2 watts max; -15 +5% VDC, 600 mA max,
9 watts max.
Power inputs are each protected by a 750mA M (medium time-lag) resettable fuse, and a
rectifier diode for polarity protection.
WETTED MATERIALS: 316 stainless steel, 416 stainless steel, VITON7 O-rings;
BUNA-N7, NEOPRENE7 or KALREZ7 O-rings are optional.
Omega7 makes no expressed or implied guarantees of corrosion resistance of mass flow
meters as pertains to different flow media reacting with components of meters. It is the
customers' sole responsibility to select the model suitable for a particular gas based on
the fluid contacting (wetted) materials offered in the different models.
INLET AND OUTLET CONNECTIONS: 1/4" (FMA 1400 ranges up to and above10 L/min)
or 3/8" (FMA 1400 for ranges above 10 L/min) compression fittings standard; 1/8" or 3/8"
compression fittings and 1/4" VCR7 fittings are optional.
TRANSDUCER INTERFACE CABLE: Flat cable with female 15-pin "D" connector ends is
standard. Optional shielded cable is available with male/female 15-pin “D” connector
ends. [Cable length may not exceed 9.5 feet (3 meters)]
