FL-244 | Electronet

Product Description

FL-244 Flow Indicator Totaliser is a microcontroller-based flow measurement instrument designed for accurate flow rate indication and totalisation in industrial applications. It accepts voltage (1–5 V), current (4–20 mA), and frequency (0–10 kHz) inputs, with selectable linear or square-rooted input characteristics. The unit features a bright LED display for flow rate and totalised flow, ensuring clear visibility on the panel. Advanced functions such as programmable low-flow cut-off, input averaging for turbulent flow, and software calibration enhance measurement reliability. It supports normal and batch operating modes with configurable relay alarm outputs for high, low, or batch control. Optional 4–20 mA retransmission and RS-485 MODBUS RTU communication enable seamless integration into automation systems.
