The VOLU-probe/VS Station utilizes one or more VOLU-probes, factory mounted in a rigid, welded, galvanized casing to sense and average separate total and static pressure traverses of an air stream. The station has a certified accuracy of ± 2% when tested in accordance with AMCA Standard 610. Each probe contains multiple sets of Pitot sensing ports positioned equidistant along the length of the probe. They traverse the duct cross-section and average the sensed pressures in separate internal manifolds. The VOLU-probe/VS Station is designed for applications with limited straight duct runs and/or moderately disturbed airflow. AMCA Certified in accordance with Standard 610. Patent No. 4,559,835.
