Keyence FD-H32

The Keyence FD-H32 is a high-performance clamp-on non-contact flow sensor designed for continuous flow measurement of liquid fluids in pipelines. Floating Light Automation is an authorized distributor and can offer fast delivery.

It does not require cutting pipelines or stopping production during installation, completely avoiding the problems of pressure loss, leakage and maintenance caused by traditional intrusive flow sensors.

It is suitable for pipe diameters from 25A (32mm) to 100A (114mm), and can accurately measure flow in a wide range from 0.5L/min to 200L/min, which is ideal for water, coolant, pure water and other low-viscosity fluid flow monitoring scenarios.

Relying on Keyence's unique ultrasonic detection technology, the FD-H32 can achieve measurement accuracy of ±3% of the full scale even in pipelines with small pipe diameters and unstable flow rates, and can output real-time flow data through analog and digital interfaces, which is convenient for direct access to PLC, SCADA and other industrial control systems.

It also supports 2-level switch output for flow upper and lower limit alarm, helping users achieve automated process control and abnormal condition warning.

FD-H32 vs. Other Keyence FD Series Models: Comparison Guide

Keyence's FD clamp-on flow sensor series includes multiple models to adapt to different application scenarios. Below we compare the FD-H32 with other mainstream models to help you choose the most suitable product:

Key selection suggestions:

· If your project is to measure the flow of small-caliber pipelines below 25mm, we recommend choosing theFD-Q20C, which has higher cost performance for micro flow measurement.

· If you need to measure flow in large-caliber pipelines over 114mm, we recommend matching theFD-V70Ato adapt to large flow range and maintain high accuracy.

· The Keyence FD-H32 is the most versatile choice for most industrial production lines and equipment supporting pipelines, and can cover the demand for flow monitoring of most common pipe diameters.

Recommended Matching Combinations

To meet the different needs of different automation systems, we provide the following common matching solutions based on engineering practice:

1. Standalone Display + Alarm Matching

For users who only need local display and flow alarm, it is recommended to match the Keyence FD-A100 display amplifier unit.

This combination does not require connecting to an upper control system, can directly display real-time flow on the site, and set the upper and lower limit flow alarms to output switch signals, which is suitable for independent equipment, small cooling systems, water treatment equipment and other scenarios.

2. Industrial Control System Access Matching

For projects that need to integrate flow data into PLC or DCS systems, the FD-H32 itself supports 4-20mA analog output and NPN switch output, which can be directly connected to most mainstream PLCs on the market.

For users who need Modbus communication, we recommend matching the Keyence NX series modular controller to achieve digital data transmission, which is convenient for remote monitoring and data statistics.

3. Multi-point Flow Monitoring System Matching

If you need to monitor flow at multiple measurement points on the same production line, you can configure multiple FD-H32 sensor heads connected to a centralized FD-M series amplifier unit, which saves installation space and reduces system cost compared with configuring independent amplifiers for each point, which is suitable for automated production lines with multiple processes and multiple measurement points.

Common Application Scenarios

· CNC machine tool coolant flow monitoring: Real-time monitoring of cutting fluid supply to avoid processing quality problems caused by insufficient coolant flow.

· Industrial chiller water circulation monitoring: Real-time grasp of circulating water flow to ensure heat exchange efficiency of chiller.

· Small reverse osmosis pure water equipment flow monitoring: Non-contact measurement will not pollute pure water, and meet the hygiene requirements of the food and pharmaceutical industry.

· Production process water supply flow control: Real-time flow feedback to achieve automatic adjustment of water supply volume, save water resources.

· Cleaning equipment water flow monitoring: Ensure that the cleaning water flow meets the process requirements to ensure the cleaning effect of workpieces.

FAQ

Q: What is the detection principle of the Keyence FD-H32?

A: The FD-H32 employs a dual-mode detection principle combining "Delta TOF" (Time of Flight difference) and "Pulse Doppler":

Delta TOF: Calculates flow velocity by measuring the difference in propagation time of ultrasonic waves traveling with and against the flow.

Pulse Doppler: Enhances measurement capability for complex conditions, such as fluids containing air bubbles or high-viscosity liquids.

This dual-mode combination enables the FD-H32 to maintain stable measurements even with complex fluids—such as those containing air bubbles, or those that are high-temperature or high-viscosity.

Q: Which pipe materials is the FD-H32 compatible with?

A: The FD-H32 is compatible with metal pipes and rigid resin pipes.

Q: Which liquids is the FD-H32 suitable for?

A: It is suitable for all liquids, including water, purified water, oil, chemical solutions, and coolants.

It maintains stable measurements even under complex conditions, such as the presence of air bubbles, high temperatures, or high viscosity.
