The FMI-100 Series is for
flowmeters and controllers with
analog 0 to 5, 5 to 10, 0 to 10 Vdc
or 4 to 20 mA input output interface,
where flow indications/control,
totalizers or alarm functions are
required. Also when re-transmission
of the flow rate and/or totalizer
functions via optically-isolated pulse
output or serial communication is
desired. Local or programmable set
point control for flow controllers (no
host PC presence required).
The graphical LCD has large
13 mm (0.51") digits for flow rate
and 5.5 mm (0.21") for total and can
be set by user to simultaneously
show different combination of the
flow parameters: flow rate,
totalizers, flow alarms, and
diagnostic events. All configuration
parameter settings are easily
accessed via a simple user-interface
menu driven by a 6 button key-pad
which can be password-protected.
For flowmeters and/or flow
controllers, FMI-100 provides
jumpers selectable for 0 to 5 Vdc or
4 to 20 mA analog set point control
signals. The flow rate set point can
be adjusted locally via key-pad,
remotely via host PC using digital
communication interface, or
programmed in advance using
built-in 16 steps batch table with
ramping up/down support.
The programmable flow pulse
output operates independently
from the totalizers and based on
configuration settings can provide
pulse frequency proportional to
instantaneous fluid flow rate. The
FMI-100 provides two independent
programmable flow totalizers.
Both totalizers are updated every
100 ms and can be set to activate
different events. Main totalizer
accumulated total is backed-up
in EEPROM memory every
second. And it provides the user
with a flexible alarm/warning
system that monitors the fluid
flow for conditions that fall outside
configurable limits as well as visual
feedback for the user via the LCD
or via an optically-isolated output.
All process data and settings can
be read and modified manually via
local LCD key-pad or through the
digital RS232 or RS485
communication interface. Proprietary
ASCII software interface command
set and free Communication Utility
software are provided.
