Designed to support both metal and resin pipes, it offers high repeatability and stability with selectable analog or pulse outputs. The unit operates on 20–30 VDC and features a bright dual-row LED display with real-time flow indication and diagnostic icons. It includes an EEPROM memory for long-term data retention, flexible response times ranging from 0.5 s to 60 s, and built-in protection against reverse polarity, surge, and short circuits. Its durable stainless-steel and engineering-plastic housing ensures reliable performance in harsh industrial environments such as chemical processing, cooling systems, and fluid delivery applications. Key Features: Non-Invasive Measurement: Clamp-on design eliminates the need for pipe modification or flow interruption. Wide Flow Range: Supports flow rates up to 200 L/min (1″) or 300 L/min (1¼″). Multi-Fluid Compatibility: Measures various liquids including water, oil, and chemicals with no contact contamination. Dual Digital Display: 4-digit, dual-line LED with flow rate, stability level, and status indicators for easy monitoring. High Repeatability: Accuracy up to ±0.15 % F.S. depending on response time setting. Selectable Output Modes: Configurable NPN/PNP control, pulse, error, or analog (4–20 mA/0–20 mA) outputs. EEPROM Data Backup: Integrated memory stores totalized flow and setup data for over 10 years. Durable Industrial Design: IP65/IP67 enclosure rated for demanding environments. Flexible Mounting: Stainless-steel bracket and clamp system suitable for a variety of pipe types. Stable Power Operation: 20–30 VDC Class 2 supply with low current consumption (≤130 mA). The FD-Q32C combines versatility, durability, and ease of installation, providing precise flow monitoring for critical liquid-handling applications.
