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

D-1

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.
