FD-61 digital controller
FD-61
The FD-61 flow sensor in FD61 series module delivers precise fluid measurement through its FD-61 digital controller, optimized for industrial process monitoring and control systems.

Product Description

The FD-61 flow sensor is a high-precision industrial device designed for real-time monitoring and control of fluid flow rates. Part of the FD61 series module family, it features 2 analog inputs, 3 digital outputs, and direct connectivity with up to 4 external modules, including the FD-61 digital controller for seamless system integration. It supports RS-485 and Modbus communication protocols, operates within a 12-24V DC voltage range, and functions reliably in temperatures from -20°C to 70°C. Ideal for water treatment, HVAC, and manufacturing industries, this sensor offers ±0.5% accuracy, a compact 3.5-inch OLED display, and a detection range of 0.1-500 L/min. Its robust design ensures durability in harsh environments, though periodic calibration is recommended for optimal performance. The module lacks built-in battery support, requiring external power for operation.
