PROGRAMMABLE INTERFACE DISPLAY FOR RATE, TOTAL AND CONTROL COMMANDS

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.
