Read verified buyer reviews ↓OverviewThe Keyence FD-Q20C revolutionizes liquid flow measurement through its sophisticated non-contact clamp-on design. This sensor is specifically engineered to precisely track fluid movement within metal pipes ranging from 20 mm to 25 mm in outer diameter. Installation is exceptionally fast and does not require any pipe alterations, fluid drainage, or manufacturing halts, ensuring your operations remain continuous. It is perfectly suited for diverse industrial environments, including essential cooling systems, detailed chemical processes, and general factory automation. The FD-Q20C features a robust IP65-rated enclosure, guaranteeing dependable performance even in demanding conditions by protecting against dust and water ingress. By employing advanced ultrasonic technology, this device delivers accurate flow data without ever touching the fluid, which prevents contamination and minimizes maintenance requirements. Achieve unparalleled simplicity of use and consistent results with a sensor built for contemporary industrial needs.Key Features Non-Invasive Clamp-On Design: Install easily without cutting pipes, draining liquids, or risking fluid contamination, maintaining uninterrupted processes. Wide Metal Pipe Compatibility: Functions perfectly on common industrial pipe materials like stainless steel, copper, and iron. Optimized for 20-25 mm Pipes: Custom-designed for accurate flow measurements on pipes with external diameters between Ø20 mm and Ø25 mm. Extensive Fluid Versatility: Reliably monitors diverse liquids, including water, coolants, various chemicals, and oils. Real-time Digital Diagnostics: When connected to a compatible FD-Q Series controller, gain instant flow readings and critical operational insights. Tool-Free Quick Setup: Complete installation in under a minute using an intuitive, tool-free mounting mechanism. Industrial-Grade Durability: Features a rugged, IP65-rated housing, offering superior defense against harsh industrial elements. Seamless Controller Integration: Fully compatible with Keyence FD-Q Series controllers for extended capabilities and system coordination. Technical Specifications Model: FD-Q20C Compatible Pipe Outer Diameter: Ø20 to Ø25 mm Detection Method: Ultrasonic, clamp-on Supported Pipe Material: Metal (stainless steel, iron, copper) Supported Fluids: Water, coolant, chemicals, oil (please consult the detailed fluid compatibility list for specific applications) Flow Range: Varies depending on fluid type and pipe characteristics; typically 0 to 100 L/min Accuracy: ±3% of reading (typical performance under controlled conditions) Operating Temperature: 0 to +60°C Protection Rating: IP65 (dust tight and protected against low-pressure water jets from any direction) Mounting: Clamp-on with integrated, secure locking mechanism Cable Length: Typically 2 m Power Supply: Provided directly via a compatible Keyence controller Applications Automated Line Cooling Systems: Precisely monitor the flow of cooling water to avert overheating and ensure peak performance of critical machinery. Chemical Batching and Dispensing: Accurately track chemical flow rates without direct contact, enhancing safety and preventing contamination of sensitive substances. Pump and System Verification: Real-time monitoring of pump output and flow consistency, ensuring stable and reliable operation in industrial processes. Facility Utility Management: Comprehensive oversight of water, oil, and various process lines, optimizing resource use and operational efficiency across the entire facility. HVAC and Building Management: Monitor water flow in heating, ventilation, and air conditioning systems for energy efficiency and proactive maintenance. Food & Beverage Processing: Ideal for non-invasive measurement of ingredient or cleaning fluid flows where cleanliness is paramount.
