Product Description P/N: FD-Q20C
Description
The Keyence FD-Q20C is a clamp-on digital flow sensor designed to measure liquid flow rates through metal or resin pipes without the need for pipe modification. Part of the advanced FD-Q Series, this model combines non-intrusive sensing, rugged construction, and simple installation with accurate flow monitoring for various fluids — including water, oils, and chemicals. Featuring a 4-digit dual-row LED display, the FD-Q20C provides real-time visualization of flow and status indicators, while maintaining a high degree of protection with an IP65/IP67-rated enclosure.

Information About FD-Q20C
The FD-Q20C is a 15A/20A type sensor main unit ideal for industrial flow monitoring in environments where liquid contact must be avoided. Using ultrasonic detection technology, it accurately measures flow from the outside of the pipe—making it ideal for sanitary and corrosive fluid applications. The sensor supports both metal and resin pipes, handling temperatures up to 85°C (185°F), and can manage flow rates up to 100 L/min (26.4 G/min) depending on pipe size.
It features both digital and analog outputs (NPN/PNP switchable, 4–20 mA/0–20 mA) and IO-Link communication, making it suitable for integration into smart factory systems. EEPROM memory backup ensures long-term data retention and stable performance even after power loss.
Key Features:
- Clamp-On Design: Non-intrusive installation — no need to cut or alter the pipe.
- Dual Output Function: Digital (NPN/PNP) and analog (4–20 mA/0–20 mA) outputs.
- High Visibility Display: Dual-row 4-digit LED with flow, output, and stability indicators.
- Wide Compatibility: Works with both metal and resin pipes (15A–20A sizes).
- Supports Various Liquids: Handles water, oil, and chemical solutions.
- Fast Response Time: Selectable from 0.5 ms to 60 s for precision or stability.
- Rugged Construction: Stainless steel and PPS housing ensures long life in harsh conditions.
- High Protection Rating: IP65/IP67 for resistance to dust and water.
- Memory Backup: 10+ year EEPROM data retention (1 million+ read/write cycles).
- Environmental Durability: Withstands vibration, temperature, and humidity fluctuations.
- Simple Setup: Tool-free mounting with one-touch clamp bracket.
