Utilize Anywhere: Versatile Application
The FD-H Series offers unparalleled versatility in where and how it can be used.
Any Pipe
Monitor flow on more pipes than ever before, including braided hoses. Clamp-on flow monitoring has never been more versatile.
- Iron/Copper/Stainless Steel: [" to 1"]
- Rigid Plastic/PVC: [" to 1"]
- Hose/Tube: [13 to 63, 0.51" to 2.48"] (Standard Type, High-Temp Type)
- High-Pressure Hose: [13 to 63, 0.51" to 2.48"]
Any Liquid
Improvements in the sensing technology in the FD-H Series make it possible to detect the majority of liquids. From DI water to high viscosity liquids, the FD-H Series can provide consistently stable detection from outside of the pipe or hose.
- Water
- DI Water
- Chemicals
- Coolants
- Oils
- High Viscosity Liquids
Any Condition
Bubbles in the liquid flow have long been a problem for clamp-on flow sensors, but not anymore. The new hybrid detection method, utilized by the FD-H Series, makes it possible to continue detecting in the presence of bubbles or particulates to provide unmatched stability.
Nearly Any Temperature
Even under extreme circumstances where the pipe temperature is exceedingly hot, the FD-H Series can still provide a solution. The High Temperature models offer excellent heat resistance and can be exposed to pipe temperatures of up to 180°C (357°F).
Unmatched Features
The FD-H Series is packed with features designed for user convenience and robust performance.
- Detachable Display: View all the pertinent data and make adjustments with ease by separating the display from the sensing head. Accessibility is no longer limited by sensor placement.
- Rotatable Display: Allows for flexible viewing angles.
- Highly Visible Indicators: Clear visual cues for status.
- All-In-One Display: No manuals necessary with clear menus and even clearer displays. From easy to read graphs to historical data, the FD-H provides display options for any user. One year of data is stored and can be output via USB.
Complete Process Monitoring
Extend Beyond Flow Sensing to Understand the Full System
The FD-H Series does not stop at simply monitoring flow; it can also integrate with up to two other devices (e.g., temperature, concentration, level sensors) to provide a complete picture of your machine's performance. This helps optimize equipment usage and prevent costly downtime.
Examples of Complete Process Monitoring:
- Heat transfer control for molds [Flow Rate + Temperature]
- Monitoring of mold release agent [Flow Rate + Level]
- Quality control during quenching [Flow Rate + Concentration]
- Coolant reservoir monitoring/filling [Flow Rate + Concentration + Level]
FD-H Series Detection Principles
The FD-H Series employs advanced ultrasonic technology for accurate flow measurement.
Delta TOF [Time of Flight Method]
This method determines flow rate by monitoring two ultrasonic signals (one moving with the flow, one against) and measuring the time difference. This provides consistent and stable readings regardless of external factors like temperature changes.
Pulse Doppler
This method works effectively in the presence of bubbles or particulates by transmitting and receiving a pulse. The difference in frequency of the returned pulse correlates to the liquid's speed and thus the flow rate.
Hybrid Detection Principle
The sensor automatically switches between Delta TOF and Pulse Doppler detection methods based on the amount of bubbles present, ensuring seamless transition and no delays in detection.
Measurement Accuracy
The FD-H Series is equipped with a proprietary algorithm that achieves a measuring accuracy of ±3.0% of RD (reading value). It is also resistant to environmental changes and provides stable detection.
Various Detection Modes to Suit Any Application
The FD-H Series offers flexible detection modes and I/O configurations.
- Instantaneous Flow Mode: Detects if instantaneous flow has decreased below a set threshold.
- Area Mode: Detects if instantaneous flow is outside an acceptable upper or lower range.
- Bubble Detection Mode: Detects bubbles within the pipe and provides a one-shot output.
- Analog Output: Provides a 4-20 mA or 0-20 mA signal representing the flow rate.
Mix and Match IO to Fit Your Needs: The four I/O channels (Ch1-Ch4) can be configured for control outputs, analog outputs, or external inputs, allowing customization for various applications.
Three Unique Types
The FD-H Series is available in three distinct types to suit different environmental and application needs:
- Standard Type: Suitable for general applications, compatible with fluids up to 85°C (185°F). Features built-in temperature sensor and hybrid detection.
- High-Temperature Type: Designed for high-temperature fluids up to 180°C (356°F), requiring an ultra-high-temperature couplant for temperatures above 140°C (284°F).
- Hose Type: Specifically designed for monitoring flow in hoses, featuring a bracket that maintains uniform pressure for stable detection, even with easily deformed hoses. Compatible with high-viscosity liquids.
Lineup and Accessories
The FD-H Series offers a comprehensive lineup with various models and optional accessories.
- Models: Available in Standard, High-Temperature, and Hose types, with different rated flows and supported pipe sizes.
- Accessories: Includes heavy duty protection covers, stabilization brackets, display unit protection covers, and connection cables for separating the display unit. Power supply cables and IO-Link conversion cables are also available.
Sensors That Can Connect to the Multi-Port
The FD-H Series allows integration with other KEYENCE sensors for comprehensive process monitoring.
- Temperature Sensors (FI-T Series): Connect via M8 4-pin to M12 4-pin cables for simultaneous flow and temperature measurement.
- Concentration Sensors (FI-C Series): Digital Refractometers (Probe type and In-Line type) can be connected for concentration monitoring.
- Level Sensors (FL Series): Sensing Guide Pulse Level Sensors can be integrated for liquid level detection.
A Y-shaped connector is required for connecting multiple sensors. The display unit can also be used standalone (FI-1000).
