The FLOWSIC200 is the industry-leading ultrasonic solution for non-contact flow velocity and direction measurement. Unlike traditional point-measurement sensors (like pitot tubes or vanes) that only capture local data, the FLOWSIC200 measures across the entire tunnel width. This provides a representative average value that is absolutely critical for precise ventilation control and emergency smoke extraction.

Representative Accuracy: Point-sensors are often "fooled" by local turbulence near tunnel walls. FLOWSIC200 uses cross-duct ultrasonic technology to give a true average of air movement.
Extreme Maintenance Reduction: With no moving parts and a 5-year maintenance cycle, you significantly reduce the need for hazardous tunnel closures and risk to service personnel.
Energy Cost Optimization: Precise data allows for dynamic fan control. Even a 5% increase in measurement accuracy can lead to 30%+ savings in fan electricity consumption.
Immediate Emergency Response: In the event of a fire, the FLOWSIC200 accurately detects air direction and velocity to ensure smoke is pushed away from evacuation routes.
Hanyu Supply Reliability: We provide compliant technical selection and specialized logistics for infrastructure projects, ensuring your tunnel safety systems meet global standards.
The Challenge: A 5km highway tunnel operator faced exorbitant energy bills and frequent sensor failures caused by heavy soot buildup on traditional vane anemometers.
The Hanyu Solution: The tunnel was retrofitted with the FLOWSIC200 system from
The Result: The system provided stable readings despite the high-soot environment.
The Impact: The operator implemented dynamic fan speed control, resulting in a 30% reduction in annual energy usage. Furthermore, the move to a 5-year maintenance schedule saved thousands in manual labor and road closure costs.
Q1: How does the FLOWSIC200 handle the corrosive environment of a tunnel? A: The sensor heads are available in Grade 2 Titanium or Stainless Steel, which are highly resistant to the salt, moisture, and chemical pollutants (NOx/SOx) typically found in high-traffic tunnels.
Q2: Is the FLOWSIC200 compliant with international tunnel standards? A: Yes. It fully complies with the latest RABT (Germany), ASTRA (Switzerland), and RVS (Austria) regulations, ensuring it meets the highest safety benchmarks for road and rail infrastructure.
Q3: Can this be integrated with a central control system? A: Absolutely. For comprehensive monitoring and reporting, it is ideally paired with the [SICK Flow-X Series] flow computer or integrated into the tunnel's SCADA system via standard industrial outputs.
Q4: How is my business data protected during the inquiry process? A: At Hanyu Zhilian, we prioritize your privacy. All information submitted via
