FL-600 PTC | Electronet

Product Description

FL-600 PTC Flow Indicator Totaliser is a microcontroller-based flow measurement instrument designed for accurate pressure- and temperature-compensated flow indication and totalisation. It supports three independent inputs for flow, temperature, and pressure, ensuring precise measurement in dynamic process conditions. The unit features a clear LCD display for flow rate and totalised flow, with selectable linear or square-root input characteristics. Advanced functions such as programmable low-flow cut-off, input averaging for turbulent flow, and software calibration enhance reliability. It offers normal operation mode, configurable relay alarm outputs, and optional 4–20 mA retransmission. With RS-485 MODBUS RTU communication and availability in DIN standard, IP-65 field mount, and CMRI-certified flameproof enclosures, the FL-600 PTC is suited for demanding industrial applications.
