1.0 Description

FMA 2700, 2800, 3700, & 3800

Omegaʼs FMA Series mass flow meters and controllers utilize a
capillary type thermal technology to directly measure mass flow.
No temperature, pressure, or square root corrections are
required.

The FMA Series is available with an LCD display and linear 0-5
or 4-20 ma output. Display and outputs read in direct engineering
units. Engineering units may be mass units such as Gr/s,
LB/H...or in volumetric units referenced to a standard pressure
and temperature I.E. SCCM, SLPM, SCFH. Omega uses 70° F
and 29.92” Hg or 21° C and 760 Torr as standard reference
conditions. (Others available on request).

The FMA Series wetted materials include 316 Stainless Steel,
17-4 Stainless Steel, and FKM elastomers (standard, others
available on request). The user is responsible to check wetted
materials against gas compatibility.

Omega mass flow meters are calibrated to NIST standards for a
specific gas and range selected by the customer,
however K Factors can be used to measure other gases.

FMA Series controllers use an integral inline electromagnetic
proportional valve to control the mass flow rate. Command signal
is supplied by the onboard set point pot or an
external 0-5 VDC supplied to the D connector.

Omega cost saving design supplies a complete flow
measurement and control system in one compact package
making it ideal for OEM, laboratories, and process control
applications.
