The FMA-4100/4300 Series flow
rate can be displayed in 23 different
volumetric flow or mass flow
engineering units including a user
specific selection. Flowmeters can
be programmed remotely via
RS232 or RS485 (optional).
FMA-4100/4300 flowmeters support
various functions including,
programmable flow totalizer, high
and low flow alarm, automatic zero
adjustment, 2 relay outputs, jumper
selectable 0 to 5 Vdc or 4 to 20 mA
analog outputs, status LED
diagnostic, storage of up to 10
different gas calibrations, internal
or user-specific K-factors. Display
models have local 2 lines x 16
characters LCD display with
adjustable back light provides flow,
total and diagnostic reading
simultaneously. The digital RS232
or RS485 (optional) interface
provides access to applicable
internal data including, flow, CPU
temperature, auto zero, totalizer
and alarms settings, gas table,
conversion factors and engineering
units selection, dynamic response
compensation and linearization
table adjustment. The analog
interface provides 0 to 5 Vdc or 4 to
20 mA (jumper selectable) outputs
for flow reading.
The FMA-4100/4300 supports
automatic sensor zero offset
adjustment which can be activated
locally via the maintenance push
button or remotely via digital
interface. The auto zero feature
necessitates a condition of absolutely
no flow through the meter during the
adjustment process. Provisions are
made to either start, read, or save
the current auto zero value via digital
commands. Digital totalizer
commands include: set to zero, start
at a preset flow, assign action to a
preset value, start/stop totalizing and
read. High and Low gas flow alarm
limits can also be preprogrammed
via digital interface. Alarm action can
be assigned with preset delay
interval (0 to 3600 seconds) to
activate the contact closer (separate
for high and low alarm). Latch mode
control feature allows each relay to
be latched on or follow the
corresponding alarm status.
FMA-4100/4300 Transducers should not be used for monitoring Oxygen gas unless specifically clean and prepared for such application. See below for ordering instructions.
