The FAN-e Station is a multi-point, self-averaging Pitot traverse station with an integral air straightening honeycomb cell. It’s capable of continuously measuring fan discharges or ducted airflow with a certified accuracy of ±2% when tested according to AMCA Standard 610. The high degree of accuracy is a result of the sensor locations and sensing ports, the honeycomb airflow processing and the instantaneous pneumatic averaging of multiple pressure values. The FAN-e Station is designed for applications with very limited straight duct runs and/or highly disturbed airflow. Patent No. 3,748,901.
