FIT 9648 – Flow Indicator Totaliser

Short description: A compact microcontroller-based single-channel flow indicator and totaliser with 4–20 mA input, 8-digit totaliser, batch counter, relay output, optional retransmission, and RS485 Modbus RTU. Designed for applications like flow monitoring, batching, dosing, and process control.

Key Features

• Rugged, state-of-the-art microcontroller-based compact design.
• Dual functionality: flow rate indication / 8-digit flow totalising and batch counter mode.
• Accepts 4–20 mA DC input (linear or square root, factory set).
• User-configurable flow rate and totaliser ranges, scalable via keypad.
• Displays instantaneous flow rate (5-digit) or 8-digit totaliser (toggle by key).
• One relay output, selectable for flow rate or totaliser setpoint (230 VAC, 1A).
• Manual or optional remote reset for totaliser.
• Built-in 24VDC, 100 mA excitation supply for powering transmitters.
• True 4–20 mA retransmission output for external indicators, recorders, or PLCs.
• Optional RS485 communication with MODBUS RTU protocol.
• Battery-backed RAM for storing totaliser values and setpoints.
• Compact 48 × 96 mm panel mounting enclosure.
