VOLU-trol/F Measurement and Control Station

The VOLU-trol/F Measurement and Control Station utilizes the VOLU-probe Pitot sensing technology to continuously measure and control ducted airflow. The combination of the integrated honeycomb cell air straightener/equalizer, precision sensor locations, pneumatic averaging of a large number of sensed airflow pressures and the patented symmetrical averaging assure an accuracy of ±2% or better. The flexible design has no size or capacity limits and makes the VOLU-trol/F well suited to VAV applications where noise control and installed system cost are important. Patent No. 3,685,355.
