Fluid Components International (FCI) presents the industry’s broadest
selection of Modbus compatible thermal mass flow meters with the addition of
the Modbus communication protocol to their new ST80
Series, the recently enhanced ST51A/ST75A Series, and ST100
Series and multipoint MT100
For Modbus-based measurement and control systems, with air or gas flow
rate components, FCI can now provide an optimal, highest value flow meter
solution matched to the application. FCI thermal mass flow meters with Modbus
I/O are available for line sizes from 6mm to the largest of stacks and ducts,
and every size in-between. They are designed to measure the flow of air and
more than 200 different gases, including inert and hydrocarbon-based, in both
pure and mixed compositions.
Thermal mass air/gas flow meters are direct mass flow measurement
devices, have no moving parts to foul or clog, and require no routine
maintenance, helping achieve lowest installed cost and superior service life.
Available from AMS Instrumentation and Calibration, FCI’s family of
Modbus compatible thermal flow meters ranges from small, compact models to high
feature, high performance and high accuracy products. Models are available that
carry global agency approvals for Ex installations – both Div.1/Zone 1 and
Div.2/Zone 2 types. Four of the product ranges carry independently evaluated
SIL compliance (IEC 61508) ratings for use in safety instrumented system
All FCI thermal flow meters are available in a vast choice of process
connections to ensure compatibility with virtually any piping and installation
criteria. Inherently dual function, the instruments can provide flow and
temperature measurement, as well as totalised flow and outputs over the Modbus
The Modbus option for all five FCI model series flow meters meets the
EIA/TIA-485 standard. Transmission is via RTU or ASCII with standard MS (16 bit),
standard LS (16 bit) or Daniel extensions (32 bit). In addition to Modbus,
FCI’s thermal air/gas flow meters also provide 4-20 mA, analogue outputs, pulse
outputs, and/or other digital bus communications of HART, Foundation Fieldbus,
Profibus-PA and Profibus-DP.
