FL-244 OC | Electronet

Product Description

FL-244 OC Flow Indicator Totaliser is a microcontroller-based flow measurement instrument designed for accurate indication and totalisation of flow in industrial applications. It supports voltage (1–5 V), current (4–20 mA), and frequency (0–10 kHz) inputs, with selectable linear or square-root characteristics. The unit features a clear LCD display for flow rate and totalised flow, along with programmable low-flow cut-off and input averaging for turbulent flow conditions. It offers normal and batch operation modes with configurable relay alarm outputs for high, low, or batch control. Optional 4–20 mA retransmission output, RS-485 MODBUS RTU communication, and 24 V DC transmitter power supply enhance system integration. Available in DIN standard, IP-65 weatherproof, and CMRI-certified flameproof enclosures, the FL-244 OC ensures reliable performance in demanding industrial environments
