HVAC Flow Detection Solution – Honeywell TK-FFSU01 | TK Series
The Honeywell TK-FFSU01 is a surface mount flow sensor engineered for reliable fluid flow detection in commercial HVAC systems, building automation, and hydronic control applications. Designed for straightforward pipe-surface installation without pipe cutting or inline insertion, it delivers dependable on/off flow status to DDC controllers and BAS panels.
Where This Product Is Used
- Commercial HVAC Systems – Chilled water and hot water loop flow verification in AHUs, FCUs, and central plant equipment.
- Building Automation Systems (BAS/BMS) – Provides flow presence feedback to DDC controllers (Honeywell Spyder, Excel, Niagara-based systems) for pump status confirmation and energy optimization.
- Hydronic Heating & Cooling – Monitors flow in boiler circuits, chiller loops, and heat exchanger piping.
- Pump Proof-of-Flow – Confirms pump operation for safety interlocks and alarm annunciation in mechanical rooms.
- Industrial Process Monitoring – Light-duty process lines requiring non-invasive flow status detection.

Why Engineers Specify This Model
- Non-Invasive Installation – Surface mount design eliminates pipe cutting, welding, or system shutdown during installation, reducing labor cost and downtime.
- Honeywell Ecosystem Compatibility – Integrates directly with Honeywell DDC controllers, Spyder units, and third-party BAS via standard digital input wiring.
- Proven Field Reliability – TK Series sensors are specified by mechanical engineers and BAS integrators globally for their consistent performance in commercial building environments.
- Simplified Commissioning – Minimal calibration required; flow/no-flow threshold is factory set for typical HVAC applications.
- Reduced System Risk – No wetted parts means zero risk of leaks at the sensor installation point.

Application-Specific FAQ
- Q: Can the TK-FFSU01 be used on plastic (PVC/CPVC) pipes?
- A: Surface mount flow sensors rely on acoustic or thermal coupling to the pipe wall. Performance on plastic pipe may vary — consult the Honeywell TK-FFSU01 installation guide or contact our technical team for application confirmation.
- Q: What is the minimum flow velocity required for reliable detection?
- A: Refer to the Honeywell TK-FFSU01 datasheet for minimum flow velocity thresholds. Typical HVAC chilled/hot water systems operating within design flow ranges are well within specification.
- Q: Is this sensor compatible with glycol solutions?
- A: Yes. As a non-invasive surface mount sensor, the TK-FFSU01 is compatible with glycol-water mixtures commonly used in freeze protection applications, as the sensing element does not contact the fluid.
- Q: What output signal does the TK-FFSU01 provide?
- A: The TK-FFSU01 provides a digital (dry contact / switched) output indicating flow / no-flow status, suitable for direct wiring to DDC digital input points.
- Q: Can I get a datasheet or submittal document?
- A: Yes — contact support@konmask.com and reference model TK-FFSU01. We can provide Honeywell product documentation to support your project submittal package.
