Duct & Pipeline Airflow Sensor – Air Velocity and Air Volume with RS485 & Analog
A high-precision duct-mounted airflow sensor designed to measure air velocity and calculate air volume in ventilation and exhaust systems. Supports RS485 Modbus and standard analog outputs for easy integration with HVAC, BMS, and industrial control systems.
This duct and pipeline airflow sensor is engineered for accurate measurement of air velocity in ventilation ducts, exhaust systems, and industrial pipelines. Using a high-sensitivity airflow measurement unit, the sensor provides fast response and reliable performance, even at low air speeds and in harsh environments such as fume and exhaust ducts.
The device can calculate real-time air volume based on a user-configured duct cross-sectional area, allowing both air speed and airflow rate data to be transmitted to control and monitoring systems. Multiple output options—including RS485 Modbus RTU, 4–20 mA, 0–5 V, and 0–10 V—ensure compatibility with PLCs, HVAC controllers, BMS, SCADA, and data acquisition systems.
With strong EMC protection, tool-free wiring terminals, and a sealed duct-mount design, this sensor is well suited for industrial sites with variable-speed drives and high electromagnetic interference.
