ST100A Series Flow Meter GENERAL
Fluid Components International LLC 5
Flow Transmitter/Electronics
■ Operating Temperature:
Single Point System: -40 °F to 140 °F [-40 °C to 65 °C]
Two Point System: -40 °F to 100 °F [-40 °C to 60 °C]
■ Input Power
AC: 100 VAC to 265 VAC, 50 Hz to 60 Hz
DC: 24 VDC (19.2 – 28.8 volts)
■ Power Consumption
■ Battery Backup (for RTC)
Industrial-spec 3V Lithium coin cell type CR2450N
■ Outputs
Analog
Standard: Three (3) 4-20 mA outputs*, 0-1kHz, or 0-10 kHz
pulse/frequency (pulse width = 500 µsec; available multipliers:
0.001, 0.01, 0.1, 1.0, 10.0, and 100.0).
4-20 mA outputs are user assignable to flow rate, temperature or
if so equipped, pressure; outputs are user programmable to full
flow range or subsets of full flow range; pulse/frequency output is
user selectable as pulse for external counter/flow totalizer, or as
0-1 kHz or 0-10 kHz frequency representing flow rate.
* Outputs are isolated and have fault indication per NAMUR
NE43 guidelines, user selectable for high (>21.0 mA) or low
(<3.6 mA)
HART (comes standard with analog outputs), V7 compliant.
Digital
Standard: USB, Ethernet (service and configuration ports only),
and Modbus RS-485
Optional: F
OUNDATION Fieldbus H1 or PROFIBUS PA
FF Physical Parameters
Maximum Network Input Voltage - Ui (in V) = 32
Maximum Network Input Current - li (in mA) = 13
■ Auxiliary Inputs
One 4-20 mA input channel for FCI-administered special configura-
tions to allow ST100A Series to accept inputs from external devices
such as gas analyzers, gas composition, or pressure sensors.
■ Enclosures
Main Transmitter/Electronics:

■ Data Logger
User programmable for readings per time increment to a maxi-
mum of 1 reading/second; removable, circuit board-mounted
8 GB microSD (secure digital) memory card supplied,
■ Readout/Display (Option 1):
• Large backlit 2" x 2" [50 mm x 50 mm] LCD for display of digital
flow rate, analog bar graph of flow rate, total flow, and
temperature; user selectable engineering units, and alarm/fault
status indication.
• User programmable 17 alphanumeric character field
associated with each calibration group.
• Set-Up & Service mode displays text and service codes.
• Display is electronically rotatable in 90° increments to optimize
viewing angle.
Note: For units without the display option, the service port (USB
or Ethernet) lets a PC configure/manage the instrument via the
ST100A Series configurator utility.
■ Readout/Display and Optical Touch Buttons (Option 2)
Includes the Readout/Display Option 1 items, plus adds four
keypad/buttons for the user interface.
• Four (4) optical touch buttons for user programming of
instrument set-up and service interrogation.
• User programming and setup via the front panel.
• O
ptical touch button activation through front window – no need
to open enclosure to access or activate.
• Set and adjust the meter or interrogate diagnostics in-situ,
even in HazEx installation.
