FIT (Pulse) – Flow Indicator Totaliser

Short description: A microcontroller-based single-channel flow indicator and totaliser that accepts pulse input signals, displays flow rate and 8-digit totaliser, with relay outputs, optional retransmission, and RS485 Modbus RTU communication. Ideal for flow monitoring, batching, and dosing applications.

Key Features

• Rugged microcontroller-based system.
• Accepts pulse input proportional to flow rate (0.1 Hz to 10 kHz).
• Dual functionality: instantaneous flow rate display and 8-digit flow totalising.
• User configurable flow rate and totalising ranges (scalable by keypad).
• One relay output (can be configured for flow rate alarm or totaliser).
• Manual or optional remote reset for totaliser.
• Optional 4–20 mA retransmission output for PLCs, recorders, or external indicators.
• Optional RS485 communication with MODBUS RTU protocol.
• Built-in 24VDC, 100 mA excitation supply for powering external flow transmitters.
• Battery-backed RAM stores totaliser value and setpoints.
• Compact panel-mount enclosure (96 × 96 mm).
